To provide a boat with improved buoyancy body imparting light weight, high strength, and high abrasion resistance to the buoyancy body.SOLUTION: A boat 100 with an improved buoyancy body is in a substantially tubular and U-shape and includes: a first clad layer 11; a buoyancy body 1 including foam material 12 filled inside the first clad layer 11; a bottom plate 2 placed on the bottom of the buoyancy body 1; and a tail plate 3 placed on a rear end of the buoyancy body 1 and the bottom plate 2. The first clad layer 11 of the buoyancy body 1 is composed of a first inner layer 111 and two first outer layers 112 covering both sides of the first inner layer 111 with the first inner layer 111 in a meshed state and the first outer layers 112 in a sheet state. Due to such a composition, the buoyancy body 1 is imparted characteristics such as light weight, high strength, and high abrasion resistance.SELECTED DRAWING: Figure 2

    【課題】浮力体に軽量、高強度および高耐摩耗性の特性を持たせるように浮力体が改良されたボートを提供する。【解決手段】浮力体の改良されたボート100は、概して管状で且つU字形を呈し、第1クラッド層11と、第1クラッド層11の内部に充填された発泡材12とからなる浮力体1と、浮力体1の底部に配置された底板2と、浮力体1と底板2の後端に配置された尾板3と、を備えている。浮力体1の第1クラッド層11は、第1内層111と、第1内層111の両側を覆う2つの第1外層112からなり、第1内層111はメッシュ状を呈し、第1外層112はシート状を呈す。このような構成により、浮力体1に軽量、高強度、高耐摩耗性などの特性を持たせることができる。【選択図】図2
