In this embodiment, the storage section 14 substantially matches the height of the surface of the floor 11, but if the height of the cabin 2 is high, the front part of the floor 11 may be recessed to form a storage section if necessary. .

The structure for fixing the cabin 2 to the hull 1 is as shown in FIGS. 9 and 10. In FIG. 9, the right half shows the upright position of the cabin 2, and the left half shows the inverted state. A coaming 14 protruding upward from the general surface is formed on the inboard side of the deck portion 12, and the upper surface of the coaming 14 forms a receiving portion 13. A sealing gasket 15 is attached to the receiving portion 13. Receiving part 1
A fixing member 16 having approximately the same height as the deck part 1
2, and a fixing bolt 17 is provided protruding from the fixing member 16. Fixing member 16
A considerable number of bolts are provided on the deck portion 12, and a mounting hole 26 is bored in the mounting portion 23 of the cabin 2 in alignment with the bolt 17 of the fixing member 16 provided therein. Then, the butterfly nut 1 is screwed onto the bolt 17.
8 is prepared, and when the cabin 2 is in the normal position, as shown on the right side of FIG. Attach the wing nut 1 to the inserted bolt 17.
8 are screwed together and tightened to be fixed to the hull 1 in a watertight manner, and in the inverted state, the inverted mounting surface 25 is placed and abutted on the gasket 15 of the receiving part 13, as seen on the left side of FIG. and is similarly fixed to the hull 1.

In the hull structure of a small boat having the above configuration, the cabin 2 can be appropriately inverted and used by operating the wing nut 18 if necessary. In the upright position, the inside of the cabin 2 is kept watertight, so people can rest and store their belongings inside, and it can also be used in the event of rain. In the inverted state, the back surface of the cabin 2 forms an extension of the floor 11, which can be used as a work space for fishing or other tasks. Even in this case, watertightness is maintained, so water will not leak between the cabin 2 and the hull 1.

11 and 12 show another embodiment of the present invention, in which the right half of FIG. 11 shows the cabin 2 in the upright position and the left half in the inverted state. In this embodiment, the upper surface of the coaming 14 forms a seat 13, and a structure is provided for fixing the cabin 2 there. That is, a receiving hole 13a is drilled in the receiving seat 13, and a flanged sleeve 13b having a bolt insertion hole is inserted from above into the receiving hole 13a, and is solidified and fixed with a consolidating material 14a from the inside of the coaming 14.
