[0128] Although certain embodiments, configurations, and/or examples are described below, this disclosure extends beyond the specifically disclosed embodiments, configurations, examples and/or uses and obvious modifications and equivalents thereof. Thus, it is intended that the scope of this disclosure should not be limited by any particular embodiments, configurations, and/or examples described herein.

[0129] Individuals traveling across the surface of a body of water via a water transportation device, such as a windsurf board, surfboard, paddleboard, canoe, kayak, kitesurf board, hydrofoil, sailboat, boat, or the like, often desire to view underwater. The desire to view underwater can be for a variety of leisure and recreational or scientific purposes such as observing and/or quantifying marine life, observing and/or mapping the sea floor, observing coral reefs and mangroves, identifying shipwrecks and/or archeological sites, detecting or monitoring coastal erosion, or observing and/or monitoring the movement of sand, etc.

[0130] The fin devices described herein can include a housing that receives a camera therein to film underwater. The fin devices can be incorporated with at least any of the water transportation devices described herein to enable a user to capture an underwater view while traversing the surface of a body of water. In some variants, the fin devices can be incorporated with water transportation devices that facilitate underwater transportation. A fin can be an existing feature of the foregoing water transportation devices. Accordingly, the fin devices described herein can replace or be used in conjunction with one or more fins extending from the bottom surface of a water transportation device. The fin devices described herein can be incorporated into a water transportation device without significantly impacting the performance thereof, e.g., limited or no impact on handling, balance, speed, etc. Furthermore, the fin devices described herein can be aesthetically pleasing by having an insignificant impact on the profile or look of the water transportation device. For example, the fin devices can have a housing that is sized and shaped to store a camera for filming underwater that is incorporated into the body of a fin, resulting in a nominal impact on the aesthetic look of the water transportation device. The housing of the fin device can have a cap that is easily coupled and decoupled from the housing to enable a user to quickly insert and remove a camera without time-consuming or complex assembly or disassembly while still securely retaining the camera during use. The camera can be a separate feature from the fin devices (e.g., not be an integrated feature of the fin devices). For example, the camera can be disposed in the housing during use but, when not in use, removed by the user via decoupling the cap from the housing. In some variants, the fin device can have a housing for a camera in a mount portion of the fin device. The camera can at least be positioned forward or aft of the body of the fin. The fin device can include a motor that can move (e.g., rotate) the camera or a portion thereof to capture varying fields of view, such as directly under the camera, forward of the camera, aft of the camera, starboard of the camera, port of the camera, etc.

[0131] Multiple fin devices are described herein. The features of one fin device can be combined with the features of one or more other fin devices described herein. The fin devices described herein can have more or less features than those explicitly described.

[0132] FIG. 1 illustrates a user 102 traveling on a water surface 104 of a body of water (e.g., ocean, sea, lake, river, etc.) on a water transportation device 100 (e.g., a windsurf board). The user 102 is passing a sea turtle 106 that is below the water surface 104. In some instances, the user 102 may see the sea turtle 106 but be unable to discern the finer details thereof, which can be due to the reflection of light from the water surface 104, speed of the water transportation device 100, and/or due to other causes. In some instances, the user 102 may not see the sea turtle 106, which can be due to the foregoing reasons or because the user

102 is focusing on controlling the water transportation device 100. Accordingly, it can be desirable for the user to be able to view underwater in real time or record a view underwater, which can be in the form of at least video or photos.

[0133] FIG. 2A illustrates a windsurf board 101, which is an example water transportation device 100, with a fin device 200. The windsurf board 101 can have a central longitudinal axis LA. The fin device 200 can extend from a bottom surface (lower surface)

103 of the windsurf board 101. The fin device 200 can include a fin 202. In some variants, the fin 202 can be attached to the bottom of the board. In some variants, a board can have multiple fins. FIG. 2B illustrates a windsurf board 101 with three fins 203A, 203B, 203C. The fin device 200 can replace a fin of a plurality of fins, such as the middle fin 203B. For example, the middle fin 203B can be removed from the board, and the fin device 200 can attach to the bottom of the board as a replacement to the middle fin 203B . Attaching the fin device 200 to the middle fin 203B can be advantageous as to reduce the impact on performance (e.g., the directionality of the board through water). In some variants, the fin device 200 can be added to a windsurf board 101 without a fin extending from the bottom surface 103 thereof. The fin 202 can be used by a user to better control the windsurf board 101 (e.g., help facilitate controlled turning, reduce the likelihood that the windsurf board 101 will slide out from under the user 102, etc.).

[0134] The fin device 200 can include a housing 220. The housing 220 can include a cap 232 that can be coupled or decoupled from the housing 220 for insertion or removal of a camera. The camera can be a separate feature that is retained within the housing 220 during use but, when not in use, can be removed from within the housing 220. For example, after use, the user may extract the camera from the housing 220 and remove digital data (e.g., photos, videos) therefrom for viewing, charge the camera, etc. The camera can function independently of the fin device 200. The cap 232 can include a window or opening to enable the camera to capture a view underwater as the windsurf board 101 travels on the water surface 104. In some variants, the window or opening allows fluid to flow into the housing 220 with the camera therein. In some variants, the window or opening is covered by a transparent material to prevent the flow of fluid into the housing 220. In some variants, the camera is waterproof. The housing 220 and cap 232 can be configured at different positions and/or orientations on the fin device 200 to captured differing views as the windsurf board 101 travels on the water surface 104. For example, the camera may capture a view forward, behind, and/or under the windsurf board 101. As described elsewhere herein, the camera can record a captured underwater view, which can be in the form of photos or videos, that can later be viewed by the user. In some variants, the camera can wirelessly relay a captured underwater view to a display device (e.g., smartphone, smart watch, etc.) of the user, which can enable the user to view underwater while traveling on the water surface 104

[0135] FIG. 3A illustrates a kayak 105, which is an example water transportation device 100, with the fin device 200. The kayak 105 can have a central longitudinal axis CLA. The fin device 200 can replace or be used in conjunction with one or more fins already extending from a bottom surface (lower surface) 107 of the kayak 105. The fin device 200 can be added to a kayak 105 or other water transportation device 100 without a fin. For example, the fin device 200 can be added to other water transportation devices 100 with a different mount. The mount can vary based on the type of water transportation device 100. For example, a mount for a windsurf board can be different from a mount for a stand-up paddle board. FIG. 3B illustrate various types of mounts (e.g., power box, US box, slot box, tuttle box, deep tuttle box, FCS box, future box 3/4, future box * , etc.) that can be used to attach the fin device 200 to a windsurf board. In some embodiments, the mounts are integrated with the fin device 200. In other embodiments, the mount is a separate component and can be attached to the fin device 200.

[0136] FIGS. 4A-4D illustrate various views of the fin device 200 and components thereof. As described elsewhere herein, the fin device 200 can be used in conjunction with other fins of the water transportation device 100. In some variants, more than one fin device 200 can extend from the bottom surface of the water transportation device 100. In some variants, the fin device 200 is formed as an integrated feature of the water transportation device 100.

[0137] The fin device 200 can include a mount 204 that can be used to couple the fin device 200 to a water transportation device 100. The mount 204 can include an aperture 210 and/or aperture 212 that can be used to secure the mount 204 to the water transportation device 100. In some variants, the aperture 210 and aperture 212 are connected via an internal conduit. The mount 204 can include front angled surfaces 206, as shown in FIG. 4A, and/or rear angled surfaces 208, as shown in FIG. 4B. A curved surface 240 can transition between a lower surface 242 of the mount 204, as shown in FIG. 4C, and the fin 202.

[0138] The fin device 200 can include a fin 202. The fin 202 can be a variety of shapes and sizes depending on the desired performance of the water transportation device 100. The fin 202 can include a leading edge 214 and trailing edge 216 disposed on opposing edges (e.g., sides) of the fin 202. The leading edge 214 can be the edge of the fin 202 that is in the forward direction of travel of the water transportation device 100. The trailing edge 216 (e.g., the aft edge) can be the edge of the fin 202 that is opposite the leading edge 214. The leading edge 214 and/or trailing edge 216 can have varying profiles. In some variants, the leading edge 214 and/or trailing edge 216 can each define a continuous and/or smooth curve that extends to an end 218 of the fin 202. In some variants, the leading edge 214 and/or trailing edge 216 can have one or more contours of varying curvatures. In some variants, the leading edge 214 can be longer or shorter than the trailing edge 216. In some variants, the leading edge 214 can be the same length as the trailing edge 216. The leading edge 214 and trailing edge 216 can come together at the end 218 of the fin 202, which can be a tip of the fin 202. The fin 202 can be varying lengths, widths, and/or thicknesses. Changing the length, width, and/or thickness of the fin 202 can alter hydrodynamic characteristics of fluid flowing around the fin 202, housing 220, and/or proximate the bottom surface of the water transportation device 100. For example, the turbulence of fluid flowing around the fin 202, housing 220, and/or proximate the bottom surface can be manipulated, which can include reducing the turbulence. Similarly, the curvature of the edges and/or surfaces of the fin 202 can alter hydrodynamic characteristics of fluid flowing around the fin 202, housing 220, and/or proximate the bottom surface of the water transportation device 100.

[0139] The fin device 200 can have a housing 220. The housing 220 can house a camera device for filing underwater. The housing 220 can be conveniently opened or closed to insert and/or remove the camera device. The housing 220 can be varying shapes to accommodate cameras of different sizes and configurations. The housing 220 can be shaped and/or sized to reduce drag such that the impact on the performance of the water transportation device 100 is limited. In some variants, the housing 220 can be in the shape of a torpedo or bullet. In some variants, the housing 220 can be in the shape of a capsule or cylinder with conical ends. In some variants, the housing 220 can be shaped and/or sized to receive a torpedo or bullet shaped camera.

[0140] The housing 220 can be disposed at varying positions on the fin 202. The housing 220 can be integrated into the fin 202. The housing 220 can be formed as part of the fin 202. The housing 220 can extend across a portion of the width of the fin 202 or across the entirety of the width of the fin 202. As illustrated in FIG. 4A, the housing 220 is disposed on the leading edge 214. Stated differently, the housing 220 disrupts the leading edge 214. The housing 220 is disposed from behind a central longitudinal axis A of the fin device 200 to beyond the leading edge 214. The housing 220 is disposed closer to the end 218 of the fin 202 than the mount 204. The housing 220 can be disposed closer to the end 218 of the fin than to the bottom surface of the water transportation device 100, which, in some variants, can reduce the impact on the flow of fluid proximate the bottom surface of the water transportation device 100 during use. In some variants, the housing 220 can be disposed on the trailing edge 216 of the fin 202. In some variants, the housing 220 can be disposed in front of the central longitudinal axis A of the fin device 200 to beyond the trailing edge 216. In some variants, the housing 220 can extend between and/or beyond the leading edge 214 and trailing edge 216. In some variants, the housing 220 can be closer to the mount 204 than to the end 218. In some variants, the housing 220 can house more than one camera such that more than one view can be captured simultaneously (e.g., capture a view in front of and behind the water transportation device 100). In some variants, the location of the housing 220 on the fin 202 can impact hydrodynamic characteristics of fluid flowing around the fin 202, housing 220, and/or proximate the bottom surface of the water transportation device 100. In some variants, the housing 220 can be spaced away from the bottom surface of the water transportation device 100 such that hydrodynamic characteristics of fluid flowing proximate the bottom surface of the water transportation device 100 are not effected or are insignificantly effected by the housing 220. In some variants, the location and/or shape of the housing 220 can impact the quality of view captured by the camera. For example, the location of the housing 220 can alter the generation of bubbles due to turbulent flow proximate the housing 220, which can include reducing turbulent flow and bubbles produced. In some variants, the shape of the housing 220 can promote hydrodynamic characteristics that improve the quality of view captured by the camera, which can include reducing turbulent flow and bubbles produced. In some variants, the housing 220 is disposed at a distance from the bottom surface of the water transportation device 100 so as not to film the bottom surface instead of the seabed or the front view. In some variants, the housing 220 is sized to accommodate for the camera. In some variants, the housing 220 includes a thickness to resist external shocks while sailing or coming into contact with external objects, such as rocks, pebbles, submerged structures, etc. The size of the fin device 200 can vary depending on the size of the board. For example, the length of the fin device 200 can be around 25 centimeters for a small board, whereas the fin device 200 can be around 55 centimeters for a large board.

[0141] The housing 220 can include a receptacle (enclosure, cavity, pocket, compartment, chamber, socket) 222. The receptacle 222 can receive a camera device. The receptacle 222 can be integral with the fin 202. The receptacle 222 can be formed as part of the fin 202. The receptacle 222 can be centered on the fin 202. A central longitudinal axis CA of the receptacle 222, as shown in FIG. 4C, can intersect a central longitudinal axis of the fin 202.

[0142] The receptacle 222 can have an opening 224 providing access into a cavity (void, hollow, lumen) 226 that can receive the camera therein. The receptacle 222 can be a variety of shapes and/or sizes to accommodate varying camera devices. As illustrated, the receptacle 222 is a cylindrical structure but other configurations can be used, which may include prismatic shapes with varying peripheries such as polygonal. The cavity 226 can extend between the opening 224 and an end 230 of the receptacle 222. The end 230 of the receptacle 222 can be closed. The end 230 can be flat or, in some variants, curved or pointed. The opening 224 can be disposed forward of the leading edge 214. The end 230 can be disposed on an opposite side of the central longitudinal axis A of the fin device 200 relative to the opening 224. In some variants, the end 230 can be disposed between the leading edge 214 and the trailing edge 216. In some variants, the end 230 can be disposed behind the trailing edge 214. In some variants, the opening 224 can be disposed behind the trailing edge 216 and the end 230 can be disposed on an opposite side of the central longitudinal axis A of the fin device 200 relative to the opening 224.

[0143] The receptacle 222 can include threading 228 disposed proximate the opening 224. The threading 228 can facilitate a threaded coupling between the receptacle 222 and the cap 232. The threading 228 can be external, while the corresponding threading of the cap 232 can be internal. In some variants, the threading 228 can be internal and the corresponding threading of the cap 232 can be external. In some variants, another coupling technique can be used to couple the cap 232 to the receptacle 222, which may include a snap- fit, press-fit, latch(es), bolt(s), and/or others.

[0144] The receptacle 222 can be at varying orientations such that the camera housed therein can capture different underwater views. As illustrated, a central longitudinal axis CA of the receptacle 222 is substantially parallel to the lower surface 242 of the mount 204, as illustrated in FIG. 4C. The central longitudinal axis CA of the receptacle 222 may, in some variants, be parallel to the central longitudinal axis of the water transportation device 100. In some variants, the central longitudinal axis CA of the receptacle 222 can be angled relative to the lower surface 242 of the mount 204 and/or the central longitudinal axis CA of the water transportation device 100 such that the camera is angled upward toward the water surface 104 or downward toward the ground surface (e.g., seafloor, lake bottom, etc.) of the body of water upon which the water transportation device 100 is travelling. In some variants, the opening 224 can be facing rearward to capture an underwater view behind the water transportation device 100.

[0145] The fin device 200 can include a cap 232. The cap 232 can be coupled to the receptacle 222 to enclose a camera within the cavity 226, which can protect and secure the camera within the housing 220. The cap 232 can be decoupled from the receptacle 222 to access the cavity 226 and/or the camera. The cap 232 can include threading 236 to facilitate coupling and decoupling the cap 232 to the receptacle 222, as illustrated in FIGS. 4C and 4D. In some variants, however, other coupling techniques can be used, as described elsewhere herein.

[0146] The cap 232 can be varying shapes, which can include a dome, cone, and/or others. In some variants, the front face of the cap 232 has a curvature that matches the curve of the camera bullet while remaining hydrodynamic. For example, the inner side of the cap 232 and the front side of the camera can both be of a dome-shape. In some variants, the front face of the cap 232 has a non-flat hydrodynamic shape. The shape of the cap 232, such as a dome, can reduce the drag of the housing 220 to lessen the impact on the performance of the water transportation device 100. The cap 232 can include a cylindrical portion surrounding the threading 236 to facilitate a threaded connection between the receptacle 222 and the cap 232. The cap 232 can include a cap opening 234 through which the camera device can capture an underwater view. In some variants, the cap opening 234 can allow water to flow into the opening 224. In some variants, the cap opening 234 can be covered with a transparent material (e.g., sheet, panel, pane, film) to prevent fluid from flowing into the opening 224. In some variants, the cap 232 can include a pane (sheet, panel, pane, film) 238 of material, which can be offset from the cap opening 234, that prevents fluid from flowing into the cavity 226, as illustrated in FIG. 4D. The pane 238 can be disposed proximate a leading portion of the threading 236 of the cap 232. In some variants, the camera lens is disposed adjacent to (or substantially adjacent to) the cap opening 234, which can result in a better photo or video quality. In some variants, the cap opening 234 can remain open and water can flow into the cavity 226, such as when the camera is waterproof. Figure 4E illustrates a waterproof camera. The camera can be disposed between the panel and the end 230.

[0147] FIG. 5 illustrates a camera 300. The camera 300 can be received by the housing 220. The camera 300 can be torpedo or bullet shaped, as illustrated. In some variants, the camera 300 can be cylindrical or other prismatic shapes with varying peripheries such as polygonal. The camera 300 can include a pane (film, panel, sheet) 302 through which the camera 300 can capture a view, which can include videos or photos. The camera 300 can be a separate feature from the fin devices described herein. For example, in some variants, the camera 300 is not an integrated feature of the fin devices but is removably stored within the fin devices during use. The camera 300 can function independently from the fin devices described herein. The camera 300 can include a battery, lens, electronic components (e.g., memory such as a SD card), etc. to enable the camera 300 to function. The camera 300 can be stored within the housing 220 during use but conveniently removed therefrom when not in use. For example, the user may extract the camera 300 from the housing 220, remove an SD card therefrom, and view photos or videos stored on the SD card. In some variants, the camera 300 can be waterproof. In some variants, the camera 300 is not waterproof and the housing 220 protects the camera 300 from water damage.

[0148] FIGS. 6A-6D illustrate various views of a fin device 400 which can be used with a water transportation device 100. Any feature(s) shown or described in reference to the fin device 400 can be combined with any of the features of the other fin devices described herein.

[0149] The fin device 400 includes a mount 204 which can be coupled to a water transportation device 100. The fin device 400 can include a fin 202. The fin 202 can include a leading edge 214 and trailing edge 216 that are positioned on opposite edges of the fin 202. The leading edge 214 can be a continuous curve, disrupted by the housing 220, that extends between the mount 204 and the end 218. The leading edge 214 can extend to a position that is more rearward (e.g., aft) than the junction between the trailing edge 216 and the mount 204. The trailing edge 216 can include multiple contours with different curvatures. For example, the trailing edge 216 can curve rearward and then forward before extending to the end 218. [0150] The fin device 400 can include a housing 220. The housing 220 can include a receptacle 222 that can receive the camera 300. The receptacle 222 can extend from an opening 224 to an end 230. The housing 220 can include a cap 232 which can be coupled to the receptacle 222, as shown in FIG. 6A, to retain a camera. The cap 232 can include an enlarged cylindrical portion 244 that can be placed over a portion of the receptacle 222 to facilitate coupling. For example, the enlarged cylindrical portion 244 can surround internal threads of the cap 232 such that the cap 232 can be threaded onto a threaded portion of the receptacle 222.

[0151] FIG. 6B illustrates the fin device 400 coupled to a water transportation device 100. More specifically, the mount 204 is coupled to the water transportation device 100. The cap 232 is removed from the receptacle 222 of the housing 220 such that the cavity 226 of the receptacle 222 can be accessed via an opening 224. As described elsewhere herein, the cavity 226 can extend from the opening 224 to the end 230 of the receptacle 222 to facilitate receiving the camera 300. With the cap 232 removed, the threading 228 of the receptacle 222 is visible.

[0152] FIG. 6C illustrates the fin device 400 with the camera 300 disposed inside the cavity 226. As shown, a portion of the camera 300 opposite the pane 302 is disposed in the cavity 226 with the remainder extending outside the cavity 226 via the opening 224. As described elsewhere herein, the receptacle 222 can be configured to orient the camera 300 to capture a view in front of the water transportation device 100. In some variants, the camera can capture other views, such as a view behind (e.g., aft) and in front of the water transportation device 100 depending on the orientation of the camera, as illustrated in Figures 7 and 8. FIG. 6D illustrates the cap 232 coupled to the receptacle 222 with the camera 300 disposed within the cavity 226 of the receptacle 222. The cap 232 can cover the portion of the camera 300 that is extending outside the cavity 226 via the opening 224 in FIG. 6C. The camera 300 can capture an underwater view via the cap opening 234 of the cap 232, while being securely enclosed in the housing 220. The pane 302 of the camera 300 can be aligned and/or coaxial with the cap opening 234 of the cap 232. For example, a central axis of the pane 302 can be coaxial with the central axis of the cap opening 234.

[0153] FIG. 7 illustrates a fin device 500 which can be used with a water transportation device 100. Any feature(s) shown or described in reference to the fin device 500 can be combined with any of the features of the other fin devices described elsewhere herein.

[0154] Fin device 500 can include a mount 204 to facilitate coupling to a water transportation device 100. For example, the mount 204 can include the US Box illustrated in FIG. 3B. The fin device 500 can include a fin 202 with a leading edge 214 and trailing edge 216 extending to an end 218 of the fin 202. The fin device 500 can include a housing 220 disposed in the fin 202 between the mount 204 and the end 218 of the fin 202 that can house a camera, such as the camera 300. In some variants, the camera 300 can be waterproof or water resistant. The camera 300 can be of a torpedo or cylindrical shape, such as the camera illustrated in FIG. 4E or 5.

[0155] The housing 220 can include a receptacle 222 that has a cavity 226 sized and shaped to receive the camera 300. The receptacle 222 can include an opening 224 providing access into the cavity 226 that extends to an end 230 of the receptacle 222 opposite the opening 224. The end 230 can be an opening similar to opening 224. The receptacle 222 can extend between and beyond the leading edge 214 and trailing edge 216 of the fin 202. The opening 224 can be disposed in front of the leading edge 214 of the fin 202. The end 230 can be disposed behind the trailing edge 216 of the fin 202. The housing 220 can include curved surfaces 248 that extend from each of the lateral sides of the fin 202 to the outer periphery of the receptacle 222.

[0156] The housing 220 can include a cap 232 that couples with the receptacle 222 to close the opening 224 that provides access to the cavity 226. The cap 232 can be made of a transparent material, which can include polymer(s), that can enable the camera 300 to capture an underwater view through the cap 232. The cap 232 can include threads to facilitate a threaded connection with the threading 228 of the receptacle 222. The cap 232 can include a tab (flange) 250 which can be grasped by a user to rotate the cap 232 to facilitate threading the cap 232 onto the threading 228 of the receptacle 222. As described elsewhere herein, the end 230 can include an opening similar to opening 224 that can be closed with a cap similar to cap 232, which can enable the camera 300 to be oriented with the pane 302 thereof directed toward the opening 224 to capture an underwater view in front of the water transportation device 100 or to be oriented with the pane 302 thereof directed toward the end 230 to capture an underwater view behind the water transportation device 100. In some variants, one or more camera devices can be used to capture an underwater view in front of the water transportation device or behind the water transportation device. The housing 220 can include a textured surface (grooved surface, notched surface) 246 around the periphery of the receptacle 222 proximate the opening 224 to facilitate handling. For example, the textured surface 246 can enable the user to grip the receptacle 222 while tightening the cap 232. Similarly, the housing 220 can include textured surface 247 around the periphery of the receptacle 222 proximate the end 230 to facilitate handling as described above. In some variants, the housing 220 does not include a textured surface, such as a grooved surface or notched surface, which can help the flow of water while sailing.

[0157] FIG. 8 illustrates a fin device 600 which can be used with a water transportation device 100. Any feature(s) shown or described in reference to the fin device 600 can be combined with any of the features of the other fin devices described elsewhere herein.

[0158] The fin device 600 can include a mount 204 that can facilitate coupling to a water transportation device 100. The mount 204 can include an aperture 210 and/or an aperture 212 to facilitate coupling the fin device 600 to the water transportation device 100. For example, the mount 204 can include the Power Box illustrated in FIG. 3B.

[0159] The fin device 600 can include a fin 202 which can have a leading edge 214 and a trailing edge 216. The leading edge 214 and trailing edge 216 can extend to an end 218 of the fin 202. The fin device 600 can include a housing 220 that can house the camera 300 for capturing underwater views. The housing 220 can extend between and beyond the leading edge 214 and trailing edge 216. The camera 300 can be of a torpedo or cylindrical shape, such as the camera illustrated in FIG. 4E or 5.

[0160] The housing 220 can include a receptacle 222 that can receive the camera 300. The receptacle 222 can extend the width of the fin 202. The receptacle 222 can extend beyond the width of the fin 202. The receptacle 222 can include an opening 224 on one end that can provide access into the cavity of the receptacle 222. The opening 224 can be disposed in front of the leading edge 214. The opening 224 can be covered by a cap 232. The cap 232 can couple to the receptacle 222 with a threaded connection or other coupling technique, which can include at least those described herein. The cap 232 can be made of a transparent material, which can include polymers. The cap 232 can include an cap opening 234 through which the camera 300 can capture an underwater view. In some variants, the cap opening 234 can be covered by a transparent material, which can include polymer(s). In some variants, the cap opening 234 is not covered with a transparent material, such as if the camera is water proof.

[0161] The receptacle 222 can include an end 230 that can be disposed on a side of the receptacle 222 that is opposite the opening 224. The end 230 can include an opening that is similar to the opening 224 and that provides access into the cavity of the receptacle 222. The end 230 can be disposed behind the trailing edge 216. The end 230 can be covered by a cap 233, that can be similar to or the same as cap 232. The cap 233 can couple to the receptacle 222 with a threaded connection or other coupling technique, which can include at least those described herein. The cap 233 can be made of a transparent material, which can include polymer(s). The cap 233 can include an opening 235 through which the camera 300 can capture an underwater view. In some variants, the opening 235 can be covered by a transparent material, which can include polymers. In some variants, the opening 235 is not covered with a transparent material allowing fluid to flow through the opening 235, which can be the configuration with a waterproof camera.

[0162] The camera 300 can be disposed in the cavity of the receptacle 222 with the pane 302 thereof toward the opening 224 to capture underwater views in front of the water transportation device 100 or with the pane 302 thereof toward the end 230 to capture underwater views behind (e.g., aft) the water transportation device 100. In some variants, one or more camera devices can be disposed in housing 220 to capture views in front of and behind the water transportation device 100.

[0163] FIG. 9 illustrates a fin device 700 without a cap which can be used with a water transportation device 100. Any feature(s) shown or described in reference to the fin device 700 can be combined with any of the features of the other fin devices described herein.

[0164] The fin device 700 can include a mount 204 that can facilitate coupling to a water transportation device 100. For example, the mount 204 can include the Power Box illustrated in FIG. 3B. The mount 204 can include an aperture 210 and/or an aperture 212 to facilitate coupling the fin device 700 to the water transportation device 100. In some variants, an internal conduit can extend between aperture 210 and aperture 212. [0165] The fin device 700 can include a fin 202 which can have a leading edge 214 and a trailing edge 216. The leading edge 214 and trailing edge 216 can extend to an end 218 of the fin 202. The fin device 700 can include a housing 220 that can house the camera 300 for capturing underwater views. The housing 220 can extend beyond the leading edge 214.

[0166] The housing 220 can include a receptacle 222 that can receive the camera 300. The receptacle 222 can include an opening 224 on one end that can provide access into the cavity 226 of the receptacle 222. The opening 224 can be disposed in front of the leading edge 214. The opening 224 can be covered by a cap. The receptacle 222 can include threading 228 around the receptacle 222 proximate the opening 224 to facilitate a threaded connection between the cap 232 and the receptacle 222.

[0167] The receptacle 222 can include an end 230 that can be disposed on a side of the receptacle 222 that is opposite the opening 224. The cavity 226 can extend from the opening 224 to the end 230 of the receptacle 222. In some variants, the end 230 can be flat. In some variants, the end 230 can be curvy, dome shaped, round, cone-shaped, and/or the like to prevent disruption or turbulence of the water as the water flows behind the end 230.

[0168] The camera 300 can be disposed in the cavity of the receptacle 222 with the pane 302 thereof toward the opening 224 to capture underwater views in front of the water transportation device 100 with the cap securely retaining the camera 300 within the cavity 226.

[0169] FIGS. 10A and 10B illustrate a fin device with a hole for removing the camera. The fin device 200 can include a hole 1002 that can be used to remove the camera 300. Without the hole 1002, the camera can be difficult to remove from the receptacle 222. Accordingly, a hole 1002 at the end of the receptacle 222 can balance the air pressure between the receptacle 22 and the outside, making removal of the a waterproof camera easier.

[0170] FIGS. 11A and 11B illustrate a rail for holding the camera in place within the housing. FIG. 11C illustrates a protrusion 1104 on the camera that aligns with the rail in the housing. In some embodiments, the housing for the fin device can include a depression. For example, the housing can include a rail 1102 (e.g., slot, groove, recess, depression). The rail of the housing can be shaped so as to fit with the protrusion on the camera. Advantageously, the alignment of the protrusion on the camera and the depression on the housing can prevent movement of the camera, such as preventing rotational movement of the camera within the housing. In some variants, the housing can include a protrusion and the camera can include a depression that aligns with the housing protrusion. In other embodiments, the alignment of the protrusion and depression can prevent other types of movement of the camera, such as forward or backward movement.

[0171] FIG. 12A illustrates a fin device 800. Any feature(s) shown or described in reference to the fin device 800 can be combined with any of the features of the other fin devices described herein.

[0172] The fin device 800 can be incorporated with a water transportation device, which can include a water sports board (e.g., surf board, windsurf board, standup paddle board, etc.), boat (e.g., kayak, canoe, sailboat, etc.), and/or others. The fin device 800 can include a fin 202 attached to a mount 204. The fin 202, as described herein, can include a trailing edge 216 and leading edge 214. The trailing edge 216 and leading edge 214 can extend to an end 218. The mount 204 can facilitate coupling the fin device 800 to the water transportation device, such as a water sports board. The fin device 800 can be modified depending on the water transportation device with which the fin device 800 is incorporated. For example, for windsurfing, the size and shape of the fin 202 can change depending on board size, board volume, and/or the windsurfer’s sailing program (e.g., wave, free ride, race, slalom, etc.). In some variants, different mounts 204 can be used to facilitate coupling to the

[0173] The mount 204 can house an image sensor, such as a camera, and other components, as described herein. The image sensor can capture a view, which can include forward, aft, directly under, port, starboard, etc. of the fin device 800. The image sensor can capture photos, videos, and/or other image data. The image sensor can capture a view through an opening 802 of the mount 204. The opening 802 can be covered by a window, screen, panel, etc. that can include a transparent material through which the image sensor can capture image data. The opening 802 and/or covering (e.g., window, panel, screen, etc.) can be a variety of shapes and/or sizes, which can at least include oval, circular, polygonal, irregular, and/or others.

[0174] The opening 802, as shown in FIG. 12B, can be disposed in front of the leading edge 214. In some variants, the opening 802, as shown in FIG. 12C, can be disposed behind or aft of the trailing edge 216, which can be advantageous for filming aft of the fin device 800. In some variants, the opening 802 can be disposed port (e.g., left) or starboard (e.g., right) of the fin 202. In some variants, the mount 204 can include multiple openings 802 through which the image sensor can be maneuvered to capture a view. In some variants, the mount 204 can include a plurality of image sensors therein that can capture a variety of views through one or more openings 802. The opening(s) 802 can be a variety of shapes, which can include oval, circular, polygonal (e.g., triangle, rectangle, square, etc.), irregular, and/or others. The opening(s) 802 can be disposed in a surface 804 of the mount 204, which can include a bottom surface of the mount 204. The surface 804 can be positioned proximate and/or adjacent a surface of the water transportation device in contact with the water when the fin device 800 is mounted. In some variants, the surface 804 can be flush with a surrounding surface of the water transportation device in contact with the water.

[0175] FIGS. 12D and 12E illustrate an upper portion 870 of the mount 204. The upper portion 870 can be disposed opposite the surface 804. The mount 204 can include a hole 806 and a hole 807. The holes 806, 807 can be used to couple the mount 204 to a water transportation device, such as a water sports board. Screws can be inserted through the water transportation device and screwed, respectively, into the holes 806, 807 to secure the mount 204 to the water transportation device. Other methods of coupling can be used. Additionally, a variety of mount configurations can be used, which can at least include those shown in FIG. 3B. For example, the mount 204 can be a deep tuttle box.

[0176] The mount 204 can include a power button 810, which can at least include a button, switch, toggle, etc. The power button 810 can be used to activate the image sensor and/or other components in the mount 204. In some variants, the power button 810 can be virtually displayed on a display screen. In some variants, the user can activate the fin device 800 for use by manipulating (e.g., pressing) the power button 810 and coupling the fin device 800 to the water transportation device.

[0177] The mount 204 can include a memory device receptacle 812. The memory device receptacle 812 can receive and operatively connect a memory device to the image sensor (e.g., camera) and/or other components stored within the mount 204. The image sensor can capture image data and store the image data on the memory device. For example, the memory device receptacle 812 can receive a memory card or stick, such as a secure digital (SD) card, which can store image data captured by the image sensor. The memory device receptacle 812 can include a variety of configurations to facilitate receiving different memory devices. For example, the memory device receptacle 812 can be a slot to receive a SD card.

For example the seal 814 can extend around a periphery of the upper portion 870 of the mount 204. With the mount 204 secured within a hole (e.g., mount case or emplacement) of the water transportation device, the seal 814 can impede water from flowing around the periphery of the mount 204 and to upper portion 870 to protect the upper portion 870, memory device receptacle 812, battery, and/or cover 808 from water damage. The seal 814 can contact a periphery defining the hole of the water transportation device in which the mount 204 can be secured to create a watertight seal therebetween. The seal 814 can be made of a polymer, such as rubber, and/or other suitable material (e.g., waterproofing material) that can deform to create the watertight seal.

[0180] FIGS. 13 A and 13B illustrate a rear or aft portion of an example windsurf board 101 showing a mount case or mount emplacement 818 to couple the mount 204. As shown in FIG. 13A, the mount case or mount emplacement 818 can include an opening 820 in the bottom surface 103. The opening 820 can receive the mount 204 therein for coupling. The opening 820 can be a variety of shapes and/or sizes. As described herein, the seal 814 can contact a periphery defining an inside of the opening 820 to provide a watertight seal. As shown in FIG. 13B, the mount case or mount emplacement 818 can include top openings 822, which can at least include two openings, in the upper surface 816 of the windsurf board 101. In use, the mount 204 can be inserted into the opening 820 and screws and/or other coupling mechanisms can be inserted through the top openings 822 and attach to the mount 204 to couple the mount 204 to the windsurf board 101. For example, screws can extend through the top openings 822 and into the holes 806, 807 of the mount 204 to facilitate coupling. [0181] FIG. 14 illustrates features housed inside of the mount 204, which can also be referred to as a housing. The mount 204 can include a receptacle 824 that can receive a battery 826 therein. The cover 808 can cover the receptacle 824. The cover 808 can be snap fit, secured with a fastener (e.g., screw, pin, latch, etc.), press fit, etc. over the receptacle 824. The cover 808 can be coupled to the mount 204 with a hinge, which can allow the cover 808 to be pivoted open or closed. In some variants, the cover 808 can be slid open or closed. In some variants, the battery 826 can be a disposable battery. In some variants, the battery 826 can be a rechargeable battery. In some variants, the battery 826 can be recharged while housed within the receptacle 824.

[0182] The fin device 800 can include a memory 828, which can be housed in the mount 204. The memory 828 can include computer program instructions that a processor 830 (e.g., computer processing unit, microprocessor), which can be housed in the mount 204, can execute to implement one or more embodiments, actions, tasks, etc. described herein. The memory 828 can generally include RAM, ROM, and/or other persistent, auxiliary or nontransitory computer readable media. The memory 828 can store an operating system that can provide computer program instructions for use by the processor 830 in the general administration and operation of the fin device 800, which can include maneuvering an image sensor 838 to capture various views. In some variants, the memory 828, processor 830, image sensor 838, and/or memory device stored in the memory device receptacle 812 can be in communication to communicate image data captured by the image sensor 838.

[0183] The fin device 800 can include an image sensor 838 that can capture image data (e.g., images, video, etc.). The image sensor 838 can capture image data through the opening 802, as described herein. The image sensor 838 can be a camera.

[0184] The image sensor 838 can be manipulated to capture varying views through the opening 802. For example, the fin device 800 can include a motor 832, which can be a linear motor, that can actuate to maneuver (e.g., pivot, tilt, rotate, change orientation, angle, etc.) the image sensor 838. In some variants, the fin device 800 can include one or more linkages that can be manipulated by the motor 832 to maneuver the image sensor 838. For example, the fin device 800 can include a slide 834 (e.g., support, bar, rod, member, link, linkage). The motor 832 can actuate to translate (e.g., slide) the slide 834 with respect to the motor 832, which can at least include extending and retracting the slide 834 relative to the motor 832. In some variants, a coil of the motor 832 can generate a magnetic field, which can extend or retract the slide 834. The slide 834 can be coupled to a link 836, which can also be referred to as a tilt bar, support, bar, rod, member, linkage, etc. The link 836 can be coupled, which can include rigidly coupled, to the image sensor 838. In some variants, an end of the link 836 can be coupled to the image sensor 838.

[0185] In use, the translation of the slide 834 can cause the link 836 to pivot to rotate the image sensor 838 to capture varying views through the opening 802. The link 836 and the image sensor 838 can be rigidly coupled together and rotate about a pivot 844. For example, the link 836 can be coupled to the mount 204 (e.g., a panel, wall, vertical panel, vertical wall) at pivot 844, which can be by way of a rod, bolt, etc. The link 836 can be coupled to the slide 834 by way of a hinge 843. The retraction or extension of the slide 834 can move an end of the link 836 coupled to the slide 834 at the hinge 843, causing the link 836 and attached image sensor 838 to rotate about the pivot 844.

[0186] The motor 832 can be coupled to the mount 204 (e.g., a panel or wall), which can include being coupled to the mount 204 at a pivot 842 to allow the motor 832 to rotate about the pivot 842 as the slide 834 is extended and retracted relative to the motor 832. The extension or retraction of the slide 834 can increase or decrease the distance between the location at which the motor 832 is coupled to the mount 204 (e.g., the pivot 842) and the hinge 843 at which the slide 834 and the link 836 are coupled together. The configuration of a triangle defined by the locations of pivot 842, hinge 843, and pivot 844 can be used to define a relationship between the stroke of the slide 834 (e.g., distance between pivot 842 and hinge 843) by the motor 832 and the position (e.g., rotation, angle, tilting angle) of the image sensor 838.

[0187] The motor 832 can extend the slide 834 relative to the motor 832 to increase the distance between the pivot 842 and the hinge 843, causing the image sensor 838 to rotate about the pivot 844 in a first direction. The motor 832 can retract the slide 834 relative to the motor 832 to decrease the distance between the pivot 842 and the hinge 843, causing the image sensor 838 to rotate about the pivot 844 in a second direction, opposite the first direction, to a second position 840 illustrated in dashed lines, as shown in FIGS. 14 and 15, that can capture a view looking more forward of the fin device 800. [0188] In some variants, the motor 832 can activated to retract or extend the slide 834 by way of a controlled signal from the battery 826. In some variants, a positive voltage from the battery 826 to the motor 832 can extend the slide 834 relative to the motor 832 while a negative voltage from the battery 826 to the motor 832 can retract the slide 834 relative to the motor 832.

[0189] As shown in FIG. 16A, the image sensor 838 can be positioned to look directly downward through the opening 802, which can be advantageous for filming a seafloor, lake floor, etc. As shown in FIG. 16B, the motor 832 can retract the slide 834 to rotate the link 836 and image sensor 838 about the pivot 844 in the second direction to a second position which can capture a view through the opening 802 looking more forward of the fin device 800. The motor 832 can extend the slide 834 to rotate the link 836 and image sensor 838 about the pivot 844 in the first direction to a first position which can capture a view through the opening 802 looking more rearward (e.g., aft) of the fin device 800. The motor 832, in some variants, can rotate the image sensor 838 to discrete positions between the first and second positions. The motor 832, in some variants, can rotate the image sensor 838 along a continuum of positions between the first and second positions. In some variants, the motor 832 can maneuver the image sensor 838 to capture a view port or starboard of the fin device 800.

[0190] In some variants, an entirety and/or a majority of the surface 804 is made of a transparent material and/or an entirety and/or a majority of the mount 204 is made of a transparent material. In some variants, the motor 832 can rotate one or more gears to cause the image sensor 838 to rotate to capture varying views.

[0209] Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without other input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular embodiment. The terms “comprising,” “including,” “having,” and the like are synonymous and are used inclusively, in an open-ended fashion, and do not exclude additional elements, features, acts, operations, and so forth. Also, the term “or” is used in its inclusive sense (and not in its exclusive sense) so that when used, for example, to connect a list of elements, the term “or” means one, some, or all of the elements in the list. The term “and/or” has similar meaning in that when used, for example, in a list of elements, the term “and/or” means one, some, or all of the elements in the list, but does not require any individual embodiment to have all elements. [0210] Conjunctive language such as the phrase “at least one of X, Y, and Z,” unless specifically stated otherwise, is otherwise understood with the context as used in general to convey that an item, term, etc. may be either X, Y, or Z. Thus, such conjunctive language is not generally intended to imply that certain embodiments require the presence of at least one of X, at least one of Y, and at least one of Z.

[0211] Language of degree used herein, such as the terms “approximately,” “about,” “generally,” and “substantially” as used herein represent a value, amount, or characteristic close to the stated value, amount, or characteristic that still performs a desired function or achieves a desired result. For example, the terms “approximately”, “about”, “generally,” and “substantially” may refer to an amount that is within less than 10% of, within less than 5% of, within less than 1% of, within less than 0.1% of, and within less than 0.01% of the stated amount. As another example, in certain embodiments, the terms “generally parallel” and “substantially parallel” refer to a value, amount, or characteristic that departs from exactly parallel by less than or equal to 15 degrees, 10 degrees, 5 degrees, 3 degrees, 1 degree, 0.1 degree, or otherwise.

[0212] Any methods disclosed herein need not be performed in the order recited. The methods disclosed herein include certain actions taken by a practitioner; however, they can also include any third-party instruction of those actions, either expressly or by implication.
