ABSTRACT:
A rotatable wheel is mounted under a sailboat or other boat and shaped in a manner such that it will be efficient in developing a hydrodynamic lifting force to function as the boat's primary keel to resist leeway and provide directional stability. The wheel or wheels can also be used to ramp launch or haul the boat and to roll the boat about on land. In order to reduce hydrodynamic drag, a tire fitted onto the wheel forms a continuous and fair surface with the wheel wall.
