ABSTRACT:
The present disclosure relates to techniques for reducing roll motion experienced by a floating vessel. The disclosure reveals several different techniques for damping roll motion, which may be used alone or in conjunction to stabilize a floating vessel. A typical disclosed embodiment of a roll motion damping device would employ a sponson on each side of the vessel. Each sponson would typically encompass one or more baffles. And a wing keel could be located on the outside of each sponson. When all of these features are used in conjunction, they work synergistically to maximize the resistance to roll experienced by the floating vessel.
