VERVIEW
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 1 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 existing catamaran owners, this chapter
should be a reference.

All Models should have weight centered amidships when running at speed. Trimming engines so the boat is running
level is normally best for a soft ride. We’ve also had very good luck with Doelcher “Doel Fins”. Typically, you will
see about 4% fuel economy increase, combined with a very noticable decrease in side to side roll underway and at rest.
The Doel Fins also increase your ability to trim bow up or down. Doel Fins work best with engines over 360lbs for
example Honda 130’s or Yamaha 150 HPDI’s. On smaller lighter engines you may find the Doel Fins add too much
lift. You may find that one Doel Fin installed on the outside edge of each engine works well with the lighter engine
application. If you feel the ride is not feeling great, we recommend trim up, or down, or increase the speed, 80% of the
time makes a solid improvement. If the ride still hasn’t improved you may need to slow down. Trim adjustments also
can dramatically improve your speed and fuel economy. Find that spot where the speed and RPM climb to their max
without a throttle change. Too much weight forward may cause spray to come aboard or in severe conditions, the boat
could plow through the waves. When running alone or lightly loaded at high speeds, do not trim the engines too far
out from the transom or dangerous bow lifting could result. NEVER TAKE ANY BOAT TO THE POINT WHERE
YOU DO NOT FEEL IN CONTROL!

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 equip-
ment.

Catamarans offer unsurpassed steering control. The wide spacing of the engines, advanced steering components, and
handling characteristics of the Glacier Bay hull give operators exceptional maneuverability in even the tightest spaces.
Because of the superior tracking abilities of the Glacier Bay hull, oversteering can present a problem, especially for
owners accustomed to operating conventional boats. Conventional vessels have a tendency to lose tracking abilities in
rough and following sea conditions, making constant course corrections necessary. However, catamarans do not
exhibit those traits and require operators to take a “hands off” approach. To do so, relax your grip and fight the urge to
make constant corrections.
