A monohull marine platform (20) is provided which includes a plurality of bows (29,30,31) each having a flat lower keel (47) . A transverse stern seal (122) is connected to the bows using an inclined lift surface (128) and a pair of outboard seals (119,120)forming an air chamber. Pressurized ail is forced into the air chamber to form a pressurized air cushion (129) under the platfomr. Respective water flow channels (56,59) disposed between each pair of the plurality of bows diminish wave energy during operation. As the platform passes through the water, the platform utilizes a combination of flotation, pneumatic, and hydrodynamic for reduced resistance and drag.
