This simulator supports two types of engines: Twin Inboard and Single I/O; and two types of controls: Integrated shifters/throttles and the separate shifters/throttles. Select the boat type and controls at the start menu. In addition to using the shifters/throttles to steer the boat, there is a rudder available. The rudder has more of an impact in a Single I/O than it does for a Twin Inboard. In this simulator, the rudder moves clockwise and counter clockwise. You can move the rudder by dragging the white circle around the wheel. See the Hot Keys page for better resolution.
The left and right throttles can be increased if you are fighting against the wind or are just in a hurry. These throttles idle at 600 RPM and are limited to 2000 RPM because this is a “no wake zone.”
We just added bow and stern thrusters. Using a single thruster will cause the boat to rotate. Using both thrusters simultaneously in the same direction will cause the boat to move sideways. Select the thruster configuration from the startup menu.
Thanks to Thomas, we have added the follow feature according to his specification:
If you want to move a twin engine boat sideways, go forward on port engine and back on starbord engine. Then apply a left rudder. (Port propeller going forward will create angular momentum clockwise, i.e. forcing the stern to the port and the bow to the starbord, same is the result of going back on the starbord propeller. Now applying left rudder, will force the stern to the starbord.)
The stern is now forced both to the port and to the starbord. But since the propellers enforce a turning momentum to the entire ship, the bow will still go to the starbord. If enough left rudder is applied, it will overcome the port movement of the stern, and it also will go to the starbord, forcing the ship sideways in the opposite direction of the rudder.
Since the two propellers are going with the same revolutions per minute in opposite directions, there should not be any forward or backward movement of the ship (apart from momentum from previous maneuvering).
