Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small jet propulsion boat that sails at high speed on the sea with one person or two or three persons.

[Conventional technology]

2. Description of the Related Art Recently, small jet propulsion boats, which are small hulls with an engine and are designed to glide on water, have been widely used. In this ship, there is a demand to provide a storage space for storing tools and food items, but the space for providing the storage space is limited due to the small size of the hull,
In addition, there is a restriction that water can easily enter due to the low freeboard, and the water-tight structure must be used. For this reason, the conventional structure has not been provided with a suitable storage.

To solve this problem, Japanese Patent Laid-Open Publication No. Sho 62-125983 proposes a structure in which a compartment is formed below a seat.

[Problems to be solved by the invention]

In the above structure, the seat is a lid for the storage,
It is necessary to open and close the seat when taking in and out of an object, and thus there is a problem that it is not possible to take in and out of the object while the hull is running.

The present invention has been made in order to solve such a conventional drawback, and allows a small hull to take in and out objects while the hull is running without changing the basic shape of the hull. It is an object of the present invention to provide a small propulsion boat having an article storage section which is easy to use.

[Means for solving the problem]

This invention mounts an engine inside the hull and arranges a flow path communicating the water suction port and the nozzle at the stern behind the engine, while a pair of left and right foot decks are located between the foot decks and In a small jet propulsion boat having a seat formed so as to protrude, a seat portion on which an occupant sits is formed on the upper surface of the seat, and the bottom of the rear of the hull is formed in a substantially horizontal horizontal plane in the front-rear direction in side view, Inside the seat located below the seat,
Forming an article storage section partitioned from the hull interior space, forming an opening of the article storage section on the rear wall of the seat, attaching an openable / closable lid to the opening, and providing an upper wall of the article storage section; , And the foot deck is extended to the side of the article storage section, and a swelling section swelling upward is formed on the foot deck located near the article storage section.

In the above configuration, an article storage section is formed inside the seat below the seating section, an opening of the article storage section is formed in a rear wall of the seat, and an openable / closable lid is provided on the opening. Since it is attached, the lid that covers the opening of the article storage section can be opened and closed without moving the seating section, and articles can be easily taken in and out of the article storage section even at sea. Also,
Since the article storage portion is formed in the seat serving as a dead space, even a small hull does not affect the basic structure of the hull.

Further, since the article storage section is partitioned from the hull internal space, it is possible to prevent water accumulated in the hull internal space from splashing on the articles stored in the article storage section.
