The single rudder blade on a trimaran is much more easily controlled than the pair on a catamaran. Servo-pendulum systems can be used as long as the boat has tiller or mechanical wheel steering. Auxiliary rudder gears are less suitable because the outboard rudder of most trimarans makes proper positioning of the auxiliary rudder blade difficult. This type of gear also lacks the power required to cope with trimaran speeds. Double rudder systems are totally unsuitable. The two rudders of the gear would have to ride directly behind the outboard main rudder, and the auxiliary rudder would then be too close to the main rudder.

Lets start by identifying what exactly certain boats are. Sometimes the terminology can get lost on beginners, so well look at some of the most common boats and what theyre called. These boats are exactly what the name implies. They are meant to be used for fishing. Most fishing boats are powered by outboard motors, and many also have a trolling motor mounted on the bow. Bass boats can be made of aluminium or fibreglass.
