5.1 Overview
This chapter will provide information on the performance characteristics of your catamaran. This is not a
substitute for seamanship training or hands-on experience. First time boat owners should use the resources
detailed in Chapter 4 to learn proper methods of boat operation. Experienced boaters who have never
owned a catamaran should study this chapter completely. Do not assume that previous boating experience
will apply to all situations, as there are several subtle differences in the handling characteristics of twin
hulled boats. For experienced catamaran owners, this chapter should be a reference.
5.2 Motor Trim
The smooth riding characteristics of a catamaran are a result of the twin hull design. Their ability to slice
through oncoming waves is far superior to the pounding characteristics seen on conventional vessels. Motor
trim plays an integral part in how your catamaran accomplishes this. In a level or bow down attitude, your
boat will slice through larger chop but you may experience sluggish performance, a wetter ride and increased
bow steering in a following sea. In a bow up attitude the boat will perform better, but may ride less smoothly.
Experiment with the trim settings in various sea conditions to determine what you are most comfortable
with. When using the trim to correct a listing condition, imagine an “X” connecting the starboard engine to
the port bow, and port engine to the starboard bow (see drawing below).
5.2.1 Bow Up Condition
To correct a bow up condition on the port sponson, adjust the
motor trim “down” on the starboard engine. This will help the
starboard sponson to rise and level the vessel. If moving to the
lowest trim setting on the starboard engine does not correct
the list, trim the port engine “up” to assist the change. Reverse
the instructions to accommodate for a bow up condition on the
starboard sponson.
5.2.2 Bow Down Condition
To correct a bow down condition on the port sponson, adjust
the motor trim “up” on the starboard engine. This will help the
starboard sponson to fall and level the vessel. If cavitation occurs
on the starboard engine, lower it to correct the problem, then
trim the port engine “down” to assist the change. Reverse the
instructions to accommodate for a bow down condition on the
starboard sponson.
5.3 Engine Controls
All factory rigged boats will come equipped with a binnacle control specific to your
type of engine. Located at the helm, the binnacle controls the throttle, shift, and trim
mechanisms for your engine. For diagrams and general information about this system,
review pages 80 thru 83 of the Sportfish, Cruisers, Yachts Owner’s Manual. Also read the
owner’s manual provided by your engine manufacturer to determine how to operate
the features on your binnacle. If any components of this system need to be replaced,
be certain to use the same style and length as the original equipment.
