Claims

[Scope of utility model registration request]

A marine reaction system in which multiple reaction fins are twisted from the reaction fin boss that surrounds the rotatable propeller shaft in front of the propeller so that the flow of water can be bent in the opposite direction to the direction of rotation of the propeller. In the fin, a tip fin is provided at the tip of the base fin attached to the reaction fin boss, and on the side where the propeller blade rises, the installation angle of the base fin is configured to be larger than the installation angle of the tip fin, and the propeller blade A reaction fin for a ship, characterized in that, on the side where the fin descends, the mounting angle of the tip fin is larger than the mounting angle of the base fin.
