PROBLEM TO BE SOLVED: To provide a ship having a ship bottom air circulation tank which reduces the leakage of air from air tanks caused by the inclination of a hull and reduces the lightweight of the hull of a ship bottom.SOLUTION: A ship 1 has a ship bottom air circulation tank 200: comprising plural air tanks 205 which are provided by forming a hollow part 205 in a flat section 202 of a ship bottom 201 and by installing partition walls 206 inside the hollow part and are divided longitudinally and laterally, and an air supply means for supplying and storing air in the air tanks; and designed such that air in the air tanks is accelerated by water streams at the ship bottom and circulates in the air tanks. At front and rear ends of the air tanks, straightening guides 211 having shapes curved downward are provided to eliminate corners. A ratio (D/l) of the depth D to the length l of the air tanks is not smaller than 0.05 and not larger than a ratio (maximum trim/L) of a maximum trim, which is a difference between a forward draft and an after draft at the maximum trim, to the ship length L at the maximum trim.

    【課題】船体の傾斜による空気槽からの空気の漏れを減少させ、かつ船底の船体の軽荷重量を減少させた船底空気循環槽を有する船舶を提供する。【解決手段】船底201の平担部202に、窪み部205を形成し、前記窪み部の内部に、仕切壁206を設置して設けた縦横に区切られた複数の空気槽205と、前記空気槽に空気を供給し空気を溜める空気供給手段とを有し、前記空気槽内の空気が船底の水流によって加速され、前記空気槽内で循環するように設計された船底空気循環槽200を有する船舶1であって、前記空気槽の前後端部に下方に湾曲した形状の整流ガイド211を角のないように設け、前記空気槽の深さDと長さlの比(D/l)が、0.05以上であり、かつ最大トリム時の船首喫水と船尾喫水の差である最大トリムと最大トリム時の船長Lとの比(最大トリム/L)以下であることを特徴とする船底空気循環槽を有する船舶とした。【選択図】図1
