Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a multipurpose catamaran sightseeing boat that allows a large number of tourists to board and view a sea surface show space provided inside the hull from above or underwater. in between.

[Prior Art] Sightseeing boats for viewing sea shows such as water skiing held on the sea surface and for showing whirlpools and the like are well known and widely used.

However, conventional sightseeing boats hold shows such as water skiing on the side of the ship, run along with the water skiers, or stop to watch the sea show, so tourists can sit on either side of the ship's side. It can only be viewed from outside. For this reason, a large number of spectators gather on one side, causing the ship to tilt, creating a very dangerous situation.Also, since it is only possible to view the show from one side, it is difficult for a large number of tourists to fully enjoy the sea show at the same time. I can't.

Furthermore, when viewing a moving show object such as water skiing, it is extremely difficult to run a sightseeing boat together with the water skiing, and the show cannot always be viewed from the most enjoyable position.

In addition, as shown in Figure 11, when a fishing boat is moored on the side and you can watch the fishing boat unloading its nets, or you can watch an offshore diving show where you can watch ama diving from a sightseeing boat, you can watch it while moving or while the boat is stationary. Tourist ships that watch synchronized swimming or other swimming on the sea are dangerous because tourists gather on one side, and many people cannot enjoy the viewing experience.

Practical use of sightseeing boats that can safely accommodate a large number of tourists while providing the most enjoyable conditions for almost all the sightseeing shows that are held on the sea surface or underwater near the sea surface at sea and lake sightseeing spots throughout the country. is desperately needed.

The present invention was developed with the purpose of realizing this, and an important purpose of the present invention is that the hull is surrounded by a twin-hulled hull and a plurality of connecting members connecting the two hulls. By forming a show space and providing a viewing deck around this show space using the hull and connecting members, it is a multipurpose application that allows a large number of tourists to safely and enjoyably watch a stationary or moving maritime show. It offers tourist boats.

Another important object of the present invention is to provide a multipurpose sightseeing boat that can have a pool and play space on the sea at low cost.

[Means for solving conventional problems] Tourist boats have a pair of left and right hulls that are parallel to each other and formed in a vertically elongated shape, and a hull that connects the groin. The hull consists of a plurality of connecting members that form an enclosed show space in the center of the hull. A viewing deck for viewing the show space is provided on the hull and connecting members surrounding the show space, and the show space is viewed from the surrounding viewing deck.

[Operation As shown in FIG. 1, a show space 3 surrounded by a twin-hulled hull 1 and a connecting member 2 that connects the hull 1 is provided inside the hull, and A viewing deck 4 is provided around the show space 3 by a hull 1 and a connecting member 2. Water skiing, dolphin shows, etc. are held within this show space 3, and the shows are viewed from the surrounding observation deck 4.

Show objects that move on the sea, such as water skis and dolphins,
Move around the ship and take a look. The viewing deck 4 surrounding the show space 30 not only allows you to view the sea show from any angle you like, but also forms an enclosed show space 3, allowing you to safely hold a number of sea shows within the enclosed space. .

When a show such as net fishing or synchronized swimming that does not involve moving on the sea is held in Show Space 3, the boat is stopped and tourists can enjoy watching from the surrounding observation deck.

In any state of use, a hull in which two hulls are connected can reduce the inclination of the hull even if spectators are concentrated on both sides of the hull and on the viewing deck above the connecting member.

[Preferred embodiment] Embodiments of the present invention will be described below based on the drawings.

The multipurpose catamaran sightseeing boat shown in FIGS. 1 to 3 includes a pair of left and right hulls 1, and a connecting member 2 that connects the hulls 1 to form a show space 3 surrounded by the surroundings.

In order to be able to travel on the sea with little resistance, the ``Hyakuhanka'' has a vertically elongated overall shape, a tapered bow in plan, and a propulsion means for self-propulsion in the stern. .

The left and right hulls 1 are spaced apart from each other and arranged in parallel so that a show space 3 is provided between them. General 1
The distance between the ship M! ] The total length of the boat and the content of the show at sea are determined, but it is usually 2 to 30 meters, preferably 2 to 30 meters.
Adjusted to a range of 4 to 10 meters.

As shown in the figure, the hull 1 is formed to have a total length of, for example, 10 to 100 meters so as to protrude from the connecting position of the connecting member 2 to both the bow and the stern.

The hull □, in which both the bow and stern protrude from the connecting position of the connecting member 2, can particularly reduce the inclination of the hull and significantly improve the stability of the hull when viewers gather on a part of the viewing deck 4. It has its features. This is because the long hull 1 has a large buoyancy of its own, so even if spectators gather around either the left or right hull 1, one of the hulls 1 will not sink significantly, and the entire ship's left and right sides will be affected. The slope can be reduced.

Also, when spectators gather at either the front or rear connecting portion 12, the hull tilts forward and backward, but the hull 1 protruding forward and backward from the connecting member 2 can significantly reduce the forward and backward inclination.

Furthermore, as shown in FIG. 4, the hull 1 is equipped with an underwater window 5 through which the sea show can be viewed from underwater, a ballast tank 6 and water supply and drainage means (not shown) for adjusting the waterline of the hull 1. ).

In other words, when the waterline rises, the underwater window 5
When the hull 1 is in a submerged state, it is submerged in the water, and when the waterline is lowered and the ship 31 is floating, it is located at a position where it floats above the water surface, and between the hulls 1 They are provided on opposite inner sides of the hull 1 so that the show in the provided show space 3 can be seen. This underwater window 5 has a structure in which the frontage of the hull 1 is watertightly closed with a transparent plate such as glass.

The volume of the ballast tank 6 is determined to be such that the ice window 5 can be submerged underwater below the draft edge when water is supplied to the ballast tank 6. The water supply and drainage means (not shown) is the ballast tank 6.
A water pump connected to the ballast tank 6 supplies seawater to the ballast tank 6 and drains water from the ballast tank 6. In the case where the ballast tank 6 is installed above the waterline of the hull l,
The water can be drained by gravity from the ballast tank 6. Therefore, in this case, water can be drained without using a water pump by simply opening the drainage channel of the ballast tank 6 to the outside of the hull.

The ballast tank 6 is preferably disposed outside the hull 1, as shown in FIG. According to this structure, the ballast tank 6 does not get in the way of viewing the show space 3, and the show can be widely viewed from the entire inside of the hull 1.

Hull 1: Preferably, as shown in FIGS. 1 and 4, a plurality of viewing decks 4 are provided at the top and bottom. The multi-tier viewing deck 4 allows a large number of viewers to clearly see the sea show in the show space 3 and enjoy watching the sea show from above or below at any angle they like.

The lower viewing deck 4 installed above the water surface is designed to be slightly higher than the water surface with the waterline of the hull raised as shown in Figure 4. The height has been determined so that it can be viewed from above.
The observation deck 4 below the water surface allows you to watch the sea show from the underwater window 5.
It is provided in the water at the submerged position of the hull l.

The hull 1 has a height such that the connecting member 2 can be disposed above the water surface in a floating state, and the lower surface thereof floats above the water surface.゛The connecting member 2 connects the hulls 1 arranged in parallel on both sides to form an integral hull, and provides a show space 3 inside the hull. As shown in FIGS. 5 and 6, this connecting member 2 can easily guide the floating object 7 into the show space 3 along the space between the hulls 1 while keeping it afloat. It is placed a certain height above the sea surface to reduce wave resistance when traveling.

As shown in FIG. 5, when both the front and rear connecting members 2 are arranged at the same height from the sea surface, the floating object 7 can be easily guided into the show space 3 from both the front and rear directions of the hull.

As shown in FIG. 6, when guiding the floating object 7 into the show space 3 from one side of the hull, the height H7 of one connecting member is set higher than the height H2 of the other connecting member. That is, it is also possible to arrange in a state where H+>H2.

Further, the connecting member 2 may be located away from the sea surface when the hull 1 is in the floating position, and the bottom portion may be located underwater when the hull is in the sinking position.

As shown in FIG. 1, the connecting member 2 is connected to the viewing deck 4 of the hull 1, and a plurality of viewing decks 4 are provided.

The connection member 2 and the viewing deck 4 of the hull 1 are connected on the same plane and are provided all around the show space 3, which is most convenient because it allows the audience to go around the show space 3. Can be used.

The sightseeing boat shown in FIGS. 2 and 3 is shown water skiing in the show space 3 and being viewed from the surrounding area. In this case, the skier's towing row 18 is tied to the center of the bow side connecting member 2, and the skier carries the towing row 18 while the boat travels at a predetermined speed to play water skiing in the show space. View from observation deck 4. Skiers perform various acts in the show space, which can be viewed from the viewing deck.

Although not shown, it is also possible to provide two show spaces in the hull by arranging three sets of connecting members. This structure is applied when a large ship requires accommodation of several hundred angstroms or more.

The method of lifting nets for tourism within the show space 3 using the sightseeing boat shown in FIGS. 4 and 5 is to move either or both of the aquaculture net 9 and the hull, wI4
9 is relatively moved in the direction of arrow A. The aquaculture net 9 passes under the connecting member 2 and is housed in a show space surrounded by the shellfish 1 and the connecting member 2. Next, when hauling nets, as shown in Figures 4 and 7, water is supplied to the ballast tank 6 in order to lower the height of the viewing deck 4 to bring it closer to the water surface and to secure the aquaculture nets 9. to deepen the draft of the hull.

When the net lifting work is completed, the ballast tank 6 is drained, the hull is floated, and the aquaculture net 9 is pulled out from the show space 3 and separated from the hull.

Tourists can watch the fishing net show from underwater on viewing deck 4, near the sea surface, from a high position overlooking the entire area, and from underwater.

Aquaculture &! drawn into show space 3! lI9 is
A flow pipe 10 is provided around the upper end opening, and the flow pipe 10 is guided into the show space 3 by passing under the connecting member 2 while floating on the sea. As shown in FIG. 4, the net can be lifted by an operator on the work platform 11 on the float of the aquaculture 119, or from the observation deck 4.

When netting is carried out, as shown in FIG. 7, if the fish in the net are sucked up using a transparent suction pipe 12, tourists can particularly enjoy observing the state of fish farming. A transparent suction tube 12 is connected to the suction side of a fish pump (not shown) to suck in fish along with water.

The middle of the suction pipe 12 is suspended by a hanging member, and the fish in the net are sucked upward.

FIG. 6 shows an example of use in which a floating boule 13 floating on the water surface is guided into a show space. The floating boule 13, which is open at the top, is equipped with a float 14 that floats on its own, and is guided into the show space 3 in the same way as the aquaculture net 9 described above. This floating boule 13 stores water and live fish inside, and tourists enter the floating boule 3, grab the live fish, and enjoy watching the condition from the viewing deck.

In the usage example shown in FIG. 8, the wJ 21 is stretched in the show space 3 surrounded by the hull 1 and the connecting member 2, and the wJ 21 is used for swimming, playing in the waves, catching live fish, etc. in the net 21, and from the viewing deck 4. Watch this. The entire periphery of the yi21 is connected to the hull l around the show space 3 and the connecting member 2 so that people playing inside are safe, and the mesh is a mesh that allows water to pass through but not the human body. Furthermore, it must be strong enough so that it will not break even if a human body is placed on it.

In this state of use, by running the boat, you can enjoy and safely play in the water in an atmosphere that cannot be obtained in an above-ground running water pool due to water currents and waves flowing into the net, and this state can be observed from the surroundings. This allows both those in the water and those viewing the water to have fun.

Furthermore, even though you can have fun playing in the beautiful waters of the sea away from land, you are playing in the water within Show Space 3, which is completely enclosed, so there is no risk of it running out outside, and it is safe because it can be fully monitored. By changing the running speed of the boat or changing the running location, the speed of the running water and the size of the waves can be adjusted, making it safe, versatile, and fun to use. . This state of use is a very safe sport and can be thrilling, as long as the net is not torn.

Furthermore, in the sightseeing boat of the present invention, underwater and water shows such as dolphins and killer whales can be observed from the surrounding area in a fun manner.

In the sightseeing boat shown in FIG. 8, the upper opening of the show space 3 is closed by a steering deck 15. The steering deck 15 is equipped with a light shielding means 16 such as a skylight, and by opening the skylight during the day, the show space 3 is illuminated and ventilated. During night navigation, a light shielding means 16 such as a skylight is closed and a light 17 is turned on to prevent light from leaking upward from the show space 3 and obstructing the view behind the wheelhouse 18.

Therefore, the wheelhouse 18 is disposed above the steering deck 15. Furthermore, if a water-impermeable plate material through which rainwater does not pass is used for the steering deck 15, rainwater can be prevented from entering the show space 3 by closing skylights and the like during rainy weather. Therefore,
With this structure, you can enjoy the sea show regardless of whether it is rain or shine, day or night, and you can sail safely at night.

FIG. 9 and FIG. 1O show specific examples of using the show space 3 more effectively. The sightseeing boat shown in these drawings is
An openable and closable intermediate deck 19 is provided above the water surface of a show space 3 surrounded by a hull 1 and a connecting member 2.

The intermediate deck 19 shown in FIG. 9 is divided into two at the center,
Each is attached to the inside of the hull 1 via a pivot pin 20 so that it can be tilted downward from a horizontal position. This intermediate deck 19 is tilted between a horizontal position and a vertical position by a driving means (not shown).

During navigation, the intermediate deck 19 is stretched horizontally as shown by the solid line in Figure 9 and used for storage purposes, etc., and when performing a sea show, it is lowered vertically into the water as shown by the chain line. to open show space 3.

The intermediate deck 9 in FIG. 10 opens and closes the show space 3 by sliding horizontally.

This intermediate deck 19 is divided into two parts at the front and rear of the hull.
Each is housed below the connecting member 2 so as to be freely accessible.

With this intermediate deck 19, the show space 3 can be completely closed off, or a part of it can be closed off and used as a deck for storage or work, and the rest can be used for multiple purposes as a show space.
