Problem to be solved: to provide a method of designing a propeller guard, a ship, and a propeller guard for a ship capable of preventing a rupture of a propeller without lowering the propulsion performance of a ship.Propeller guard 3Approximately 1.1d-1.0d vertically downward from the propeller rotation center of propeller 2 whose rotating orbit radius is defined as DA first partition 31 extending horizontally from the propeller rotation center in the range of approximately 0.5 to 0.8 DAt a distance of approximately 1.1-d d from the propeller rotation centerFrom the propeller rotation center vertically to the end of the height of approximately 0.4 d to 1.0 DA second partition 32 extending vertically upward along the outer edge of the propellerThe third partition section 33 extends vertically upward from the propeller rotation center in the horizontal direction of approximately 0.6 to 1.0 D and extending vertically.Diagram
