A steering mechanism for a container carrier ship hull including a bow, a stern, and a container bay therebetween. The bow is provided with a set of depending lateral thruster pods, the set including a first pod disposed along a longitudinal centerline of the hull, a second pod disposed rearward of the first pod and outward from the centerline, and a third pod disposed rearward of the first pod and outward from the centerline opposite from the second pod. The first and second pods define a first longitudinal flow channel to one side of the centerline and the first and third thruster pods define a second longitudinal flow channel to the opposite side of the centerline. A fourth pod, which may omit thruster mechanisms, may be disposed along the centerline reward of the first, second, and third pods, to define with them first and second cross-centerline flow channels.

An unmanned vehicle may include a vehicle body and a propulsion system carried by the vehicle body. The unmanned vehicle may also include a maneuvering system carried by the vehicle body and a vehicle control system carried by the vehicle body. The vehicle control system may control speed, orientation, or direction of travel of the unmanned vehicle. The unmanned vehicle may also include a mount point carried by the vehicle body. An interchangeable payload deck may be removably connected to a portion of the vehicle body via the at least one mount point. The unmanned vehicle may further include a power supply carried by the vehicle body.

The present disclosure provides a hull for a vessel with a bow and stern with a deep V-shaped bow section at the front half of the hull gradually transformed to a concave bottom profile with a lateral horizontal planing surface on each side backward.

A ship includes a ship hull, and a gas supply apparatus that supplies a ship bottom of the ship hull with a gas. The ship bottom is provided with a plurality of recesses supplied with the gas. The recesses are spaced apart from each other in a width direction. Each of the recesses extends in a back and forth direction.

A buoyant pontoon includes a plumb bow having a leading edge, first and second bow surfaces extending from the leading edge and joining corresponding first and second lateral surfaces, a bottom surface joining the bow surfaces and the lateral surfaces, a stern surface extending upwardly from the bottom surface, and a top surface. The bottom surface has a transverse cross-sectional profile shape including a first outer V-shaped feature, a center V-shaped feature, and a second outer V-shaped feature. The center V-shaped feature extends a vertical distance lower than the first and second outer V-shaped features. The first bow surface and the bottom surface define an opening to a first vent located between the first outer V-shaped feature and the center V-shaped feature. The second bow surface and the bottom surface define an opening to a second vent located between the second outer V-shaped feature and the center V-shaped feature.

A hybrid catamaran which includes a rigid mono hull with a plumb bow portion and a pair of catamaran sponsons positioned on opposing sides of the hull, beginning at a selected point along the hull from the bow, extending to the stern of the boat.
