Abstract
A boat includes a longitudinal water channel along the bottom thereof. A motor driven propeller in the channel circulates water from a forward inlet end thereof to a rear outlet end thereof to advance the boat through the water. Passages are provided which communicate with the channel and which are adapted to discharge water through front and rear openings on the port and starboard sides. Gates are provided for opening these passages. A gate actuating mechanism is provided for opening the front port and rear starboard passages to rotate the boat in one direction about its own vertical axis. Another gate actuating mechanism is provided for opening the front starboard and rear port passages to rotate the boat in the opposite direction about its own vertical axis. Upon being opened, each set of gates serves to block travel of water to the outlet of the channel, and thereby divert all water through the passages.
