PROBLEM TO BE SOLVED: To provide a hull construction capable of increasing propulsive power of a craft without changing a hull shape.SOLUTION: A bulbous bow 2 of a hull 1 is provided with a seawater intake port 3, and a stern is provided with a seawater discharge port 5. The seawater intake port 3 and the seawater discharge port 5 are connected together by a passage 6 that is provided in the hull 1. The seawater taken in from the seawater intake port 3 is discharged toward a propeller 4 from the seawater discharge port 5 via the passage 6 in the hull 1. Thus, propulsive power of a craft is increased in combination with a wave-making resistance reducing effect.
【課題】船体形状を変更することなく、船舶の推進力を増加させることが可能な船体構造を提供する。【解決手段】船体1のバルバスバウ2に海水取り入れ口3が設けられ、船尾に海水吐き出し口5が設けられ、海水取り入れ口3と海水吐き出し口5とは、船体1内に設けられた通路6により連結されている。海水取り入れ口3から取り入れた海水を船体1内の通路6を介して、海水吐き出し口5からプロペラ4に向けて吐き出すことにより、造波抵抗の減少効果と相まって、船舶の推進力を増加させる。【選択図】図1
