    Abstract: There is disclosed a dual rudder system and method of improving the maneuvering ability and versatility of marine vehicles in navigable waters. A dual rudder steering assembly may be utilized in conjunction with a propeller of a marine vehicle. Moreover, multiple dual rudder steering assemblies may be utilized in conjunction with multiple propellers. A system for retrofitting existing marine vehicles with the disclosed devices is also disclosed, as well as a method of retrofitting existing marine vehicles with the steering system. Therefore, the disclosed steering system is compatible with pre-existing steering controls.

    Abstract: A flexible steering fin and passive cambering keel for sailboats having fundamental simplicity yet enhanced performance and superior operation in terms of design and components. The steering fin is a relatively short and elongated flexible blade with its leading edge fixed beneath the hull. A rod passing through the hull functions as a simple lever controlling the trailing edge of the blade, which provides both tilt and curvature for unique handling and ease of use. A separate flexible keel provides the function of tilting the keel as it is cambered, for greater lift. A unique fundamental mastless wingsail is also disclosed having minimal components and simplicity of operation. A mastless wingsail is also disclosed which utilizes a tensioned rod to replace known sail supports.
