よりなされている。2. Description of the Related Art In a small planing boat, an upper deck is joined to a hull that forms the lower part of the hull, but the hull that has been used so far is generally of the single plate type (design registration No. 4).
49793). Due to structural requirements, such as increasing the strength of the hull and creating a closed buoyancy chamber to secure the buoyancy of the hull during flooding, there are also hulls that have a double structure inside and outside. This one has an outer hull that forms the outer shape of the lower part of the hull and an inner hull that is joined to the inner surface of the outer hull. To form the inner hull, a core material is added to the inner surface of the outer hull. Is covered by a hand lay-up method.

う不都合もある。As described above, the conventional double-structure hull is a system in which a core material is added. Therefore, it takes a lot of time to prepare the core material, and the hand lay-up is required. Because of this, the workability of creating the internal hull is poor, and there is the inconvenience that the unnecessary core material remains after the creation.

Since it has ribs that project inward and extend in the front-rear direction, the strength of the hull is improved. Further, not only the core material as described above need not be prepared, but also the core material need not be added at the time of forming the inner hull, which facilitates the work. Moreover,
There is no possibility that the core material will remain in the hull and increase the weight.
