Abstract
A maneuverable towcraft consisting of a partial hull structure to which is removably attached at least three downward-projecting fins. A first ventral fin of sufficient size and draft is located along the craft's centerline, toward the front of the craft. A second and third fin, smaller in size and draft relative to the ventral fin, are laterally spaced-apart at a station aft of the ventral fin. The towline attachment to the towcraft is at a point above the craft's operative waterline and situated such that the towline line-of-force intersects, or very nearly intersects, the ventral fin's effective vertical zero-moment line for normal towline attitudes. Maneuvering of the towcraft by its one or more riders is accomplished by differential drag means.
