A suffix added to boat configuration names which denotes how many hulls a boat has, especially three or more.
E.G. a boat with three hulls is a trimaran, a boat with four hulls is a quadrimaran, and so forth.
The advantage to multiple hulls are largely twofold: first, for roll stability and second, for making sharper hulls that more efficiently cut through the water, decreasing drag.
Does anybody think V-hulls are cool anymore? All I see now are whatever-marans with, like, two or three hulls out there now.
