To provide a boat with a keel structure mixed with foam material, which prevents water from entering the keel structure.SOLUTION: A boat 100 with a keel structure mixed with foam material comprises a nearly tubular- and U-shaped floating body 1, a bottom plate 2 provided at the bottom of the floating body 1, a tail plate 3 provided at the rear end of the floating body 1 and of the bottom plate 2, and a keel structure body 4 provided at the bottom of the bottom plate 2. The keel structure body 4 has a concave shape recessed downward, protrusion 41 formed at the bottom, and a concavity 42 formed at the top. A foam material 5 is filled in the concavity 42. As a result, it is possible to prevent water from entering the keel structure body 4.SELECTED DRAWING: Figure 5

    【課題】水がキール構造体内に入らないようにした発泡材入りキール構造体のボートを提供する。【解決手段】発泡材入りキール構造のボート100は、略管状及びU字形を呈す浮力体1と、浮力体1の底部に設けられる底板2と、浮力体1と底板2の後端に設けられる尾板3と、底板2の底部に設けられるキール構造体4と、を備えている。キール構造体4は、下向きに窪んだ凹状を呈し、底部に突出部41が形成され、頂部に凹部42が形成されている。凹部42には、発泡材5が充填される。これにより、水がキール構造体4内に侵入することを抑制できる。【選択図】図5
