The present invention provides manageable buoyancy and adjustable vessel draft which makes navigation possible in both shallow and deep waters without changing the total vessel weight or its given payload. The seakeeping characteristics and dynamic stability of the vessel are also managed by changing the shape of the buoyancy and by controlling corresponding wet vertical depth necessary for safe operations and navigation in both shallow and deep waters for all purposes. The ability to operate and navigate in both shallow and deep waters makes coastal boarding and unloading possible in shallow waters.

[ I claim:] [1.] A vessel designed for operation in deep water which can be navigated and boarded and unloaded in very shallow water comprisinga main passenger and cargo carrying hull having two similar opposite sides,a pair of similar elongated side hulls each having a front end, a center section and a rear end which lie along the opposite sides of the main hull,each of the side hulls being connected to the main hull by a pair of similar horizontally oriented rotatable connectors which permit each side hull to rotate 90.degree. from a horizontal position floating on the surface of the water along side the main hull to a vertical position beneath the water, anda pair of dynamic stabilizers mounted respectively on the right and left side hulls.
