HULL STRUCTURE INCLUDING IN-WAVE RESISTANCE INCREASE REDUCING STEP

摘要

PPROBLEM TO BE SOLVED: To provide a hull structure including an in-wave resistance increase reducing step for reducing an in-wave resistance increase without increasing smooth underwater resistance. PSOLUTION: The hull structure includes a bolster 20 for an anchor provided in a bow 11 of a vessel 10 and the in-wave resistance increase reducing step 30 for pushing waves apart. The in-wave resistance increase reducing step 30 is provided at a lower side of the bolster 20 and at an upper side of a static water level rising position A in the bow 11 to reduce an increase of resistance by the bolster 20 in the ocean waves.
