You are going ahead on twin engines when you want to make a quick turn to port. Which actions will turn your boat the fastest?

Correct Answer: Option D — Reverse port engine; apply left rudder

Reversing the port engine creates a turning moment to port, while applying left rudder directs the propeller wash against the rudder to further assist the turn. This combination maximizes the vessel's rotational velocity, providing the fastest possible turn to port for a twin-screw vessel under headway.
