Abstract
PURPOSE:To provide a reaction fin for an economic marine vessel of simple structure and high performance at low cost. CONSTITUTION:A reaction fin device for marine vessel is provided with reaction fins 7a, 7f extended relatively longer than a propeller shaft 5a, intermediate reaction fins 7b, 7e shorter than the upper reaction fins 7a, 7f while extended below the upper reaction fins 7a, 7f, and lower reaction fins 7c, 7d. At the time of forward propulsion, the setting angle of the reaction fin of a gunwale side where a propeller wing is lowered, is defined larger than that of an opposite gunwale, while an interval between the front end of the propeller and the rear end of the reaction fin is defined 15%-25% of a diameter DP of the propeller at a position approximately 35% away from the diameter DP of the propeller from the core of the propeller shaft 5a, and the length of a gunwale wing CF of the reaction fin at the same point is defined 10%-20% of DP.
