The boat is controlled by the player lying face down, for example, by switching the left leg of the player into the water, or by moving the player's center of gravity to bank the boat from side to side. ing.

(Problem to be solved by the invention) In order for a player to board such a recreational boat from the water, it is necessary to quickly pull the hull from the water to the surface and board the boat from the top in a timely manner while lying face down. There is.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a recreational boat that allows players to board the boat while lying face down.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention is directed to a recreational boat in which a player boards the hull of the boat equipped with a propulsion device in a prone position from behind the hull from underwater. , an open part is provided at the rear of the hull, and the hull has grip parts bent upward on both sides to be gripped by a player when getting on board;
This grip portion is characterized by extending to the rearward opening of the hull.

(Operation) In this invention, the player grasps the grips formed on both sides of the boat's hull, pulls the boat rearward, and climbs onto the boat from the water, lying face down, from the upper half of the body.

At this time, the user can grasp the grips formed on both sides of the hull, reliably pull the hull backwards, and then slide into the hull while lying face down and switching the left and right hands to the front of the grips.

(Example) Next, an example of the present invention will be described in detail based on the accompanying drawings.

First, FIGS. 1 to 10 will be explained.

A hull 1 of the recreational boat is composed of a hull part 2 and a deck part 3. The hull portion 2 and the deck portion 3 are integrally molded from a foam such as polyurethane, and are covered with a reinforcing material such as glass fiber reinforced plastic (not shown).

A propulsion device 4 is fixed to a mounting portion 5 at the center bottom of the hull portion 2, and the mounting portion 5 is formed by cutting out the bottom portion of the hull portion 2. The propulsion device 4 is, for example, a screw-type propulsion device driven by an internal combustion engine, and a fuel tank 6 is housed in a recess of the mounting portion 5. It is fixed to the hull part 2 with a bracket 7.

Note that an autojet type propulsion device 4 may be used as the propulsion device 4 mentioned above. Furthermore, it is also possible to house the propulsion device 4 in the mounting portion 5 and mount it so that it does not protrude downward from the bottom. In this case, a sealed storage chamber that can be opened and closed via a hinge or the like may be formed in the deck portion 3, and the fuel tank may be stored in this storage chamber.

In the deck part 3, a boarding part 8 on which the player rides is formed by cutting out the deck part 3, and this boarding part 8 has a breastplate part 9 in the center where the player's chest rests, and arms on both sides of this breastplate part 9. It consists of a placing part 10 on which the body is placed, and a lower body placing part 11 located behind the chest plate part 9.

A handle 12 for fixing the body to the hull 1 is provided on the front side of the breastplate part 9, with its lower end fixed to the left and right mounting parts 10, and a throttle lever 13 is attached to the right handle 12.
is provided. Throttle lever 13 is handle 1
A throttle valve is opened and closed by a wire (not shown) that is passed through the internal combustion engine of the propulsion device 4 and is provided to the internal combustion engine of the propulsion device 4.

An inlet 14 for sucking air into the internal combustion engine is provided on the front side of the breastplate part 9, and the breastplate part 9 is inclined at a predetermined angle toward the lower body resting part 11 at the rear of the hull. is equipped with a breastplate member 15 made of an elastic body.

Both sides of the deck part 3 are bent upward to form a grip part 16, and the length L of the grip part 16 becomes shorter toward the rear. This grip portion 16 extends toward an open portion 17 formed at the rear of the hull 1, and extends from an end le of the open portion 17.
A is bent toward the water.

When the player grasps the grip part 16 with his left and right hands from the rear of the hull 1 and pulls the hull 1, his body is guided by the opening part 17 and he can get on the deck part 3 for playing.

Furthermore, by switching the right and left lower portions to the front side of the grip portion 16, the user can slide his/her body into the hull 1 in a prone state.

Next, the operation of this embodiment will be explained.

To board the boat 1, the player grasps the grip part 16 of the left U formed on the deck part 3 from the rear of the boat 1 underwater, easily pulls the player, and places the upper body on the boarding part 8 of the deck part 3. Then, while changing the grip on the left arm f to the IN side of the grip part 16, get into the deck part 3, place your chest against the breastplate part 9, and grip the left and right handles 12, as shown in FIG. Thereby, the body can be fixed to the hull 1 with the legs protruding outside the hull 1, as shown in FIG.

In this way, the player a puts his chest on the breastplate part 9 and h'
With the upper body turned away, the handle 12 is placed nearby.
By grasping the body, the body is strongly drawn to the chest plate 9 and comes into close contact with the chest plate 9, so that the body is reliably supported by the hull 1.

When driving the propulsion device 4 to run the boat and turn left and right, for example, as shown in Figure 10, when the right foot is placed in the water, the resistance causes the boat to turn to the right, and conversely, the left foot is placed in the water. When swapped, it will turn to the left.

In addition, if the maximum speed of the hull 1 due to the propulsion unit 4 mounted on the hull 1 is, for example, about 8 Km/h to 9 m/h, the hull 1 is banked left and right by shifting one body weight. Then, the bent end portion 17a of the open portion 17 allows for easy turning in the direction opposite to the bank direction.

In this way, a sense of unity between the hull 1 and the hull 1 is ensured while the boat is running, and smooth maneuvering is possible, for example, when the boat turns, the body and the hull 1 bank as one to the left and right as one.

TS11 to 14 show another embodiment, in which the hull part 2 and deck part 3 constituting the hull 1 are formed separately and the inside is hollow.

The hull part 2 and the deck part 3 are formed separately from synthetic resin, for example, and the flange parts 2a and 3a of the two are butted together and fixed at an appropriate number of places with rivets 18, and this joint part is molded 19. It is unified.

Further, the hull portion 2 and the deck portion 3 may be directly fixed with adhesive.

Furthermore, in this embodiment, as shown in i12 [; It is also possible to prevent it from appearing.

(Effects of the Invention) As described in item 01, this invention provides an open part at the rear of the hull, and the hull has a grip part bent upward on both sides to be gripped by a player when boarding the ship. Since the part extends to the open area in the rear direction of the hull, the user can grasp the grip part and reliably pull the hull backwards, allowing the user to board from the water with the upper body in a prone position. Furthermore, it is possible to slide the body into the hull while switching the left and right hands to the front side of the grip.
