<p>The invention provides for a versatile boat which is highly stable and maneuverable in a variety of water conditions. The boat is substantially symmetrical about a longitudinal, vertical plane and has a lower hull portion that is generally V-shaped in cross section. Connected to the lower hull portion is a generally inverted V-shaped upper hull portion which is interrupted in both the bow and stern by decks inclined toward the longitudinal plane. Positioned interiorly of the hull sections and extending substantially the length of the boat is an internal barge structure. The barge structure is spaced apart from the hull sections to define ballast compartments in between these structures. When flooded, the ballast compartments enable the boat to operate in a semi-submerged position while floating on the internal barge structure. The boat is further provided with a separate bow ballast tank which, when flooded, shifts the boat's center of gravity to further increase its stability and reduce vertical acceleration through oncoming waves. <IMAGE></p> |
