There are many ways to control the heading of the boat. Generally people trim their sails
or start the engine and simply use the rudder. An engine can be used to steer when it is in gear
, when it is in neutral and not producing thrust, the skeg is not large enough for steering
. In adverse weather
or with poorly trimmed sails
, the thrust of the engine will not be enough to overcome other forces and the rudder is required. Other ways to steer are by changing sail trim and moving weight around the boat.
It is all about balancing forces. As long as you can balance them using whatever necessary (sails, hull
drag, rudder, engine) you can steer.
