ABSTRACT:
A linkage is provided for connecting a first vessel and a second vessel such that the vessels are inhibited from rolling or yawing relative to one another but are permitted to pitch and heave relative to one another, when the first vessel is pushed by the second vessel via the linkage. The linkage also provides a streamlined transition from the rear of the first vessel to the second vessel to reduce drag and thereby reduce power requirements of the pushing vessel. The linkage is also adapted to function as a skeg to decrease the yaw of the first vessel when the first vessel is pulled by a second vessel. When used to link a pushing vessel with a pushed vessel, the linkage of this invention provides a pedestrian walkway and apparatus for transferring fluids between the two vessels.
