ABSTRACT:
A catamaran includes a pair of floats, a deck extending in the air between the pair of floats as fixedly attached thereto and a connecting member extending in the water between the pair of floats as fixedly attached thereto. The connecting member has an airfoil-shaped section so that a lift is provided to the bow of the catamaran while it is cruising. Preferably, the airfoil-shaped section is inclined to define an attack angle in a range between 15 degrees and 25 degrees and most preferably approximately at 20 degrees. When applied to a working catamaran having a rotating impeller for collecting floats, a tail section is provided as extending downstream from a downstream edge of the air-foiled section.
