The watercraft has a displacement hull and a pontoon attached to the hull. The pontoon has an elongated float and an arm, integral with the float and ... 02/22/07 - 20070039533 - Apparatus for reconfiguration of a variable-draft vessel A vertical translation mechanism for reconfiguring the hull form of a reconfigurable vessel having independently movably side hulls and a center hull is disclosed. The vertical translation mechanism includes a hydraulic-force actuator and a nonmetallic bearing. The hydraulic force actuator comprises a rod that is disposed within a hydraulic cylinder. ... 02/22/07 - 20070039532 - Multi-hull vessel adapted for ice-breaking A multi-hulled vessel for upward ice-breaking is disclosed. The vessel has side hulls that are at least partially submerged while the vessel is underway. The side hulls each have a ridge on their upper surface. To break through ice at sea, the side hulls are positioned under the ice and ... 02/08/07 - 20070028822 - Variable-draft vessel A vessel that varies its draft by adopting any one of three primary hull forms or configurations is disclosed. The primary hull forms include: a catamaran configuration, a barge configuration, and a SWATH configuration. The vessel is capable of reconfiguring between these hull forms while underway. Reconfiguration is accomplished by ... 11/16/06 - 20060254487 - Vessel hull and method for cruising at a high froude number In one aspect of the invention, a vessel has a liquid-plane greater than one meter2/(metric ton)2/3 and includes a hull having a total length and a plurality of hull portions each having a length that is less than the total length. Each hull portion buoys the vessel. Each hull portion ... 11/09/06 - 20060249066 - Ocean-going vessels Ocean-going vessels having a load carrying module supported from a pair of spaced apart hulls by legs. The legs may be articulated in two places to provide control of the spacing of the two hulls and to control the elevation of the module off the water. Dynamic control of the ... 10/26/06 - 20060236909 - Stealthy powered catamaran An articulated boat may include a pair of pontoons and a central cabin connected by pair of struts, each pair forming a parallelogram and one or more motors for changing the elevation between the central cabin and the pair of pontoons and for moving the boat through the water.
