Definitions

  • the present disclosure relates to a watercraft, more particularly, a recreational personal watercraft.
  • a personal watercraft is a small recreational watercraft that is designed to be ridden like a motorcycle or scooter on water. It is typically powered by a jet propulsion system that uses a powerful water pump to shoot a high-pressure jet of water out of the back of the watercraft, propelling it forward.
  • a personal watercraft is popular for use in a variety of water-based activities such as water sports, recreational riding, and racing. They are commonly used in lakes, rivers, and coastal areas around the world.
  • PWC personal watercraft
  • PWCs require regular maintenance and upkeep to keep them in good working condition. This can be time-consuming and expensive, and may include tasks such as winterization, engine maintenance, and hull cleaning.
  • PWCs can also have a negative impact on the environment as they can contribute to water pollution through oil and fuel leaks. Further, PWCs are typically stored on trailers when not in use, which can be bulky and difficult to store. They also require a vehicle with a hitch and sufficient towing capacity to transport them to and from the water.
  • the current disclosure provides a method of converting a jet board into a personal watercraft (PWC).
  • the method includes first providing an add-on module that is capable of being detachably attached to the jet board.
  • the add-on module itself is not motorized and it does not have a way to propel itself in water.
  • the detachably attaching step includes placing the add-on module over a front end or at least a front half of the jet board.
  • the detachably attaching step includes sliding the add-on module over a front end or at least a front half of the jet board.
  • the detachably attaching step includes inserting a front end or at least a front half of the jet board into a corresponding structure underneath the add-on module.
  • the method includes providing at least one handlebar coupled to the hull of the add-on module so a rider in a riding position may hold on to the add-on module by holding the handlebar.
  • the coupler can be a tether, a strap, a line, a rope, an elastic band.
  • the method includes providing a hook or a catcher at a distal end of the coupler.
  • the method can include attaching the hook or the catcher to a corresponding protrusion (e.g., a handle) found at rear portion of the jet board in order to keep the jet board from detaching from the add-on module.
  • This attachment can bias the jet board towards the add-on module.
  • the coupler can be a movable clamping ram, and wherein the detachably attaching and securing step can include using the clamping ram to abut the jet board against a portion of the add-on module to keep it from detaching from the add-on module.
  • the method may include using a tool to adjust the movable clamping ram.
  • the clamping ram may apply direct pressure to the lateral sides of the jet board.
  • the clamping ram may apply direct pressure to the underside of the jet board to press the jet board against the bottom of the add-on module.
  • the securing step can include wrapping a strap over the underside of the jet board and tying the jet board to the underside of the add-on module in order to keep it from detaching from the add-on module.
  • the securing step can include securing the coupler over the rear end of the jet board to keep it from detaching from the add-on module.
  • the coupler can include a fastener, such as a screw, a toggle latch, a cam lock, or any other suitable hardware so a user may fasten the fastener to a corresponding part of the jet board to keep it from detaching from the add-on module.
  • a fastener such as a screw, a toggle latch, a cam lock, or any other suitable hardware so a user may fasten the fastener to a corresponding part of the jet board to keep it from detaching from the add-on module.
  • a receiving channel as part of the hull, either under the hull or within the hull, such that a user may fit a portion of the jet board snugly between at least two inner walls of the receiving channel.
  • the receiving channel can have a shape that corresponds with an outer contour of at least a front end of the jet board.
  • the receiving channel can be disposed on an underside of the hull so that the jet board can slidingly receive therein and the bottom side of the front end of the jet board is still visible and not covered by the add-on module.
  • the receiving channel can be disposed in an interior of the hull of the add-on module to slidably receive the jet board therein.
  • the add-on module is detachably attached to the jet board by inserting at least the front end of the jet board into an opening disposed at the rear end of the add-on module.
  • the add-on module is detachably attached only to the front end of the jet board.
  • the add-on module is detachably attached only to the front end and to two rear side handles of the jet board.
  • the add-on module does not have a source of propulsion and the PWC is driven forward by the electric propulsion system of the jet board.
  • the method can further include attaching the handheld controller of the jet board to the handlebar of the add-on module, thereby allowing a user to adjust the output of the PWC while holding on to the handlebar of the add-on module.
  • the add-on module has no electrically-powered parts.

  • jet board refers to a jet-powered board or electric board both of which can be in the form of a surfboard (see 222 of Fig. 16 illustrating surfboards of various sizes), a standup paddle board (see 223 of Fig. 16 ), an electric boogie board (see 225 of Fig. 16 ), and a hydrofoil board (see 221 of Fig. 17 ) which generally has a board size and shape similar to the a boogie board (225).
  • a jet board is a watercraft that allows the rider to surf on the water without the need for waves. It is typically powered by one or two electric motors or a jet engine, which propels the board forward through the water. If the board has a hydrofoil, it is sometimes called an e-foil.
  • the inventors have discovered a quick and easy way to convert a jet board into a personal watercraft (PWC).
  • PWC personal watercraft
  • FIG. 1 generally depicts the basic structure of an add-on module 100 in accordance with the disclosure.
  • the add-on module 100 can have a relatively light overall weight, with relatively simple construction. It can have a hull 110, a bow 102, a stern 104, a left transom extension 190, a right transom extension 192, a handle grip 160, a handlebar 162, and a stem 164.
  • the contemplated hull 110 can be made of suitable materials to withstand the stresses of traveling over the water, including waves, wind, and impacts from floating debris. It can be a material that is able to withstand exposure to moisture, sun, and other elements without deteriorating or corroding over time.
  • the contemplated material can include lightweight material which can improve the PWC's speed and efficiency. This material is contemplated to have a stiffness to help the hull to maintain its shape and resist deformation while underway.
  • Such materials include natural and synthetic polymers, various metals and metal alloys, naturally occurring materials, textile fibers, and all reasonable combinations thereof.
  • the contemplated hull 110 can be made of plastic by injection molding, but the disclosure is not limited thereto. In some embodiments, the contemplated hull 110 can be made of high-density foam, but the disclosure is not limited thereto. In some embodiments, the contemplated hull 110 can be made of wood, but the disclosure is not limited thereto. Other contemplated material may include steel, aluminum, fiber-reinforced plastic (FRP), and polyethylene, but the disclosure is not limited thereto.
  • FRP fiber-reinforced plastic
  • the bow 102 can resemble the bow of a typical PWC by having the appropriate curvature consideration that can affect performance and safety.
  • the shape of the bow can affect how easily the PWC can turn and change direction. A more curved bow can allow for sharper turns, while a flatter bow may be more difficult to maneuver.
  • a PWC with a more curved bow can help to absorb and deflect waves, reducing the impact felt by the rider. This can improve the ride quality and reduce the risk of injury or discomfort.
  • the console 124 may contain instruments to display mechanical or digital gauges or provide information or entertainment. In some embodiments, this console 124 does not have any instruments and gauges and can simply be a hollow structure where the stem 164 is attached.
  • Stem 164 can or cannot be rotatable relative to the console 124.
  • a rider may turn the handlebar left and right, and such turning can be made possible by having rotatable stem 164 that is rotatably fixed to the console 124.
  • the rider may not turn the handlebar left and right.
  • the stem 164 can be fixedly attached to the console 124 and not rotatable relatively to the console 124.
  • the rider hangs on to the handlebar 162 to help keep himself or herself stabilized.
  • the hull 110 During riding over water, the hull 110 has a width such that the waterline is expected to reach both the bottom of the port side wing 170 and the bottom of the starboard side wing 172 as will be discussed in more detail in Fig. 5 .
  • the contemplated add-on module 110 can have a seat 112 behind the console 124. In other embodiments, no seat is provided, and a rider may stand behind the console 134, holding the handlebars 162. In such embodiments, the handlebars 162 would be higher thereby making it easier for a standing rider to hang on to.
  • footwell 180 on the port side and a footwell on the starboard side of the add-on module, allowing the rider to rest his or her feet.
  • the footwell 180 is contemplated to simply be a receiving structure of no mechanical moving parts.
  • the add-on module 110 has no electric-driven moving parts, but the disclosure is not limited thereto. In other embodiments, the add-on module does not have any fuel-power or electric-powered propulsion system, but the disclosure is not limited thereto.
  • Contemplated add-on module 100 can have a left transom extension 190 and a right transom extension 192 at the stern 162 of the add-on module 100.
  • These transom extensions 190, 192 can make added surface contacts with the top side of a jet board (as shown in Figs. 5 , 6 , 7 , 9 ) for stabilization.
  • the bottom sides of these transom extensions 190, 192 make no contact with the water and they are not part of the hull 110.
  • the hull 110, the port side wing 170, the starboard side wing 172, the console 124, the left transom extension 190, the right transom extension can all be a single integral piece manufactured by injection molding.
  • it can be a hollow plastic housing having all these parts.

  • the entire add-on module 100 shown in Fig. 1 can be manufactured by injection molding, and it contains no more than three pieces of moving parts assembled together.
  • FIG. 2 shows a rear view of the add-on module 100.
  • the port side wing 170 and the starboard side wing 172 are each shown to have a protruding part 120 disposed at the bottom of the port side wing 170 and the starboard side wing 172.
  • the protruding parts 120 form part of the bottom of the hull 110.
  • both protruding part 120 come sloping down toward the center longitudinal line of the add-on module 100 and abruptly ends such that the two protruding parts 120 do not meet in the mid-center line of the add-on module 100.
  • the protruding part 120 abruptly ends and sharply cuts back upwards thereby forming a groove 140.
  • the groove 140 can come in various shapes. In one embodiment, the shape of the groove 140 corresponds closely with the size and model of the jet board the add-on module 100 is designed to fit over.
  • This empty space is a docking area 130 where a jet board 200 can be inserted into and docked.
  • the grooves 140 alone are sufficient to capture the jet board 200 can keep it from falling off from the add-on module 100. That is, when a jet board 200 is docked into the docking area 130, the grooves 140 can keep the front end of the jet board 200 from any vertical movement. Any such vertical movement is undesired because during operation, an impact from a wave can easily dislodge the jet board 200 form the add-on module unless there is some means to restrict such relative vertical movement between the jet board 200 and the add-on module 100.
  • There additional securing means can include, but not limited to, a clamp (not shown), a toggle latch (not shown), a screw (not shown), a strap (not shown), a line (not shown).
  • the docking area 130 has an open bottom. In other words, the bottom of the docking area is exposed to open water. In other embodiments such as the one shown in Fig. 3 , there can be a bottom 135 to the docketing area 130.
  • the bottom 135 effectively creates a pocket to receive a jet board 100 therein.
  • the bottom 135 can prevent the jet board 200 from any vertical movement and therefore more securely keeps the jet board 200 in place.
  • the bottom 135 of the docking area 130 shown in Fig. 3 is flat, the bottom can simply be part of the bottom of the hull 110 that curves down towards a center longitudinal line and forms a center spine similar to the bottom of the hull in a typical PWC.
  • the grooves 140 essentially forms a receiving channel that is either part of the hull 100 structure, or the receiving channel and be a separate structure coupled to the hull 100. Either way, the rider would fit a portion of the jet board 200 snugly between at least two inner walls (e.g., the grooves 140) of the receiving channel.
  • a rider would place the add-on module 100 over the front end of the jet board 200.
  • This method step corresponds with the embodiment of add-on module 100 shown in Fig. 2 .
  • the rider would then slide the front end of the jet board 200 into place by making sure an engaging contact is made between the sides of the jet board and the grooves 140.
  • a rider would insert the front end of the jet board 200 into an opening at the rear end of the add-on module 100 so that at least a front end of the jet board 200 is enveloped within the docketing area 130.
  • This structure resembles a pocket. In this way, a portion of the jet board 200 is sandwiched between the bottom 135 of the docking area 130 and the seat 112.
  • a front end of the jet board 200 is in engaging contact with the add-on module 100.

  • this engaging contact further includes the bottom side of the front of the jet board 200 (not shown).
  • Figs. 5 , 6 , and 7 illustrate the add-on module 100 partially enveloping the front end of the jet board 200.
  • the battery access cover 212 of the jet board 200 appears to be just a little more than halfway covered over by the tail end of the add-on module 100. This is to say that, looking from top down and looking at the center longitudinal line of the jet board 200, this particular jet board 200 in Fig. 6 is about 50 to 60% covered by the add-on module. Notice this percentage coverage does not take into consideration how far back the add-on module's two transom extensions 190, 192 reach back beyond the tail end of the seat 112.

  • the lines of arrows 224 next to each jet board are a representation of contemplated coverages of the add-on module over the jet board.
  • the contemplated add-on module 100 has a tail end length that covers over at least the first 25% of the top side of the jet board. As illustrated in the first two top arrows, in some embodiments, the contemplated add-on module 100 has a tail end length that covers over at least the first 50% of the top side of the jet board. As illustrated in the first three top arrows, in some embodiments, the contemplated add-on module 100 has a tail end length that covers over at least the first 75% of the top side of the jet board.
