The vessel response is proportional fore and aft, as well as rotationally, to the joystick input. The farther
the joystick is pushed from the center, the more force is going to be produced forward or backward. For
example, pushing forward slightly will put the main engines in gear, continuing to the push the joystick
farther forward will incrementally throttle the engines and make the vessel move faster. Moving the joystick
port or starboard turns on and off the respective thrusters. The total amount of thrust generated is
determined by the amount of time the thrusters are on.
Callout Joystick Input Thrust Source Control Function
a Move forward Engines Proportional
Boat moves forward in speed proportional to the position of the
joystick
b Move to starboard Thrusters On and Off Boat moves sideways to starboard by turning thrusters on and off
c Move backward Engines Proportional
Boat moves backward in speed proportional to the position of the
joystick
d Move to port Thrusters On and Off Boat moves sideways to port by turning thrusters on and off
e
Rotate clockwise
or counter‑clockwise
Engines Proportional
Boat rotates around center proportionally in the direction of the
joystick rotation
Switchpad
The switchpad provides an intuitive driver interface to maneuver the vessel to port, starboard, and rotate.
Maneuvering the vessel with the switchpad is limited to close quarter operations and when docking. The
switchpad turns the appropriate thruster on in the indicated direction. The switchpad translates the push
of buttons into port and starboard thrust. For example, pressing both buttons on one side of the switchpad
causes thrust to be applied to the boat in the sideways direction. The engines are not typically used during
these maneuvers.
