Claim:
A watercraft, comprising: a hull configured to move over a body of water, said hull having a front portion, a central portion, a rear portion, a port portion and a starboard portion; a plurality of hydroskis coupled to said hull, each of said plurality of hydroskis having a lateral port side portion, a lateral starboard side portion, a bow portion, a stern portion and a bottom surface portion between said lateral port and starboard side portions; at least one of said plurality of hydroskis being selectively controlled to roll said port and starboard side edge portions back and forth about a local longitudinal axis such that each one of said lateral port and starboard side portions selectively moves deeper into the body of water than the other one of said lateral port and starboard side portions so as to generate a resultant side force against said bottom surface portion and to provide a turning force to effect navigable control of said watercraft; and wherein said bow portion of said at least one hydroski is above the body of water when on plane and only said stern portion is on the body water.
