Current Simulator - The Simulation settings are used to select a simulator from a choice of three boat/vessel models, namely, Triton (cruiser), Poseidon (work-boat) and Osaka (tanker).

Simulated vessels have a built-in controller for route navigation.

Tight/Easy Turn - The tightness of the turns that the controller makes can be set in terms of tight and easy turns using the slider. Tight turns are sharper and follow the Route closer. Easy turns are smoother than tight turns but, depending on the turn involved, the boat maybe further away from the waypoint in the Route. Differential use of propellers is also used by the built-in guidance system to make more efficient turns.

Propeller Control - Can be set to slave mode or differential. In slave mode, both propellers are locked and controlled together. In differential, the propellers can be controlled individually.

The Look Ahead Enabled feature (works only in simulation mode) enables the advanced simulation mode with which the future position of the boat is simulated based on current boat state (position, heading, rate of turn, rudder angle, engine rpms, etc.).

The Show Swath setting is useful especially when reviewing tracks and the swept path (swath) of the boat is of interest. The two screenshots shown below illustrate the use of the Show Swath setting.
