Steer Assist

WARNING

You are responsible for the safe and prudent operation of your vessel. Steer assist is a feature that can provide information on steering your vessel. It does not control the helm for you or relieve you of the responsibility of safely operating your boat. Avoid navigational hazards and never leave the helm unattended.

Steer Assist is a set of sailing features provided to help you steer on the optimal course while sailing. You must select or import a polar table before you can use the Steer Assist feature ( Polar Tables).

NOTE: Steer Assist is enabled automatically when you select or load a polar table. To deactivate Steer Assist, select Settings menu > Preferences > Navigation > Steer Assist.
