Abstract

An efficient double-ended watercraft (100) is disclosed that comprises four low-Froude number hulls (111) : two forward, two aft, two on the port side, and two on the starboard. Each hull (111) comprises an independent engine that drives a propeller shaft (212) and propeller (213) that is located amidships. The propeller shafts (212) on the starboard are collinear, as are the propeller shafts on the port. The propellers on the starboard (213) are near each other and counter rotate, as do the propellers on the port. The propellers are variable-pitch propellers. When the ferry is changes from moving forward to moving in reverse and from reverse to forward, the propellers on the starboard exchange pitch. This enables the ferry to move as efficiently in reverse as it does when forward. The propellers on the port also exchange pitch when changing from moving forward to moving in reverse and from reverse to forward.
