One or more of bow-port outlet 300, bow-starboard outlet 302, stern-port outlet 304, and stern-starboard outlet 306 may be used to move pontoon boat 100 forward in direction 172 (see FIG. 3), rearward in direction 174 (see FIG. 3), laterally towards port in direction 173 (see FIG. 3), laterally towards starboard in direction 175 (see FIG. 3), or combinations thereof.
Referring to FIGS. 24-27, an exemplary input device, a joystick 800, of user interface 240 is illustrated. Joystick 800 has a home position (its location illustrated in each of FIGS. 24-27). Joystick 800 is movable in any one of directions 802, 804, 806, and 808 or combinations thereof. The direction of movement provides an input to controller 230 of which outlets 300-306 of thruster system 200 should have water pushed out of and the magnitude of the displacement from the home position provides an input to controller 230 of the volume of water to be pushed out of the respective outlets 300-306.
Referring to FIG. 24, joystick 800 is displaced to the location marked by “X”. In this position, controller 230 pushes water out of stern-starboard outlet 306 at a first level, pushes water out of stern-port outlet 304 and bow-starboard outlet 302 at a second level less than the first level, and pushes no water out of bow-port outlet 300. The result is that pontoon boat 100 moves forward and towards port.
Referring to FIG. 25, joystick 800 is displaced to the location marked by “X”. In this position, controller 230 pushes water out of stern-port outlet 304 at a first level, pushes water out of bow-port outlet 300 and stern-starboard outlet 306 at a second level less than the first level, and pushes no water out of bow-starboard outlet 302. The result is that pontoon boat 100 moves forward and towards starboard.
Referring to FIG. 26, joystick 800 is displaced to the location marked by “X”. In this position, controller 230 pushes water out of bow-starboard outlet 302 at a first level, pushes water out of bow-port outlet 300 and stern-starboard outlet 306 at a second level less than the first level, and pushes no water out of stern-port outlet 304. The result is that pontoon boat 100 moves rearward and towards port.
Referring to FIG. 27, joystick 800 is displaced to the location marked by “X”. In this position, controller 230 pushes water out of bow-port outlet 300 at a first level, pushes water out of stern-port outlet 304 and bow-starboard outlet 302 at a second level less than the first level, and pushes no water out of stern-starboard outlet 306. The result is that pontoon boat 100 moves rearward and towards starboard.
In embodiments, the thruster systems described herein may be used in conjunction with an autonomous system to position or move the boat.
