Claims

[Scope of utility model registration request]

In order to prevent the generation of bilge vortices due to the separation of water flow along the outer skin of the hull in the bilge part of the bow or stern part, the bilge part is equipped with a long thin plate supported through struts. A ship with a bilge vortex prevention device, characterized in that the bilge vortex prevention device is arranged along the longitudinal direction of the bilge portion at a required distance from the surface of the hull outer plate.
