speeds and harder impacts at high speed. Displacement hulls provide superior handling characteristics, even at low
speed, and an improved ride in rough water. Speed and economy suffer however, since more of the hull is submerged.
World Cat has taken the best characteristics of these two designs and incorporated them in the Vectroflo™ hull. Our
proven design provides a superior ride, excellent handling characteristics in a variety of conditions, and speed with
economy of operation. To help you experience “The Ultimate Ride”, study the following sections.
5.10.1 Turning Characteristics
Turning a catamaran is slightly different than cornering on a conventional vessel. Imagine the difference between an
automobile and a motorcycle. Automobiles take turns in a flatter, more stable, manner similar to catamarans hulls,
while motorcycles pitch hard into a turn similar to a monohull. Do not underestimate a catamaran’s cornering ability
however, hard adjustments to the steering wheel can make a World Cat bite quickly and execute high performance
turns. Experiment with the handling ability of your cat so you are prepared for any situation on the water.
5.10.2 Adverse Sea Conditions
Catamarans are designed to handle some of the roughest waters in the world, but that is no substitute for common
sense. As an operator you are responsible for the safety of your passengers and vessel; therefore, your trips should be
limited by your level of experience. Planning and paying constant attention to the weather and sea conditions is
paramount. If you are forced to operate in dangerous seas however, you can be confident that your World Cat, when
operated properly, can handle them safely. Following are some tips on how to handle your boat in adverse sea
conditions:
When traveling into the wind, changing your direction a few degrees to allow one sponson to settle before the other,
can make the ride smoother and allow for increased speed.
In a rough chop with short wave intervals, increasing your speed may allow the boat to skim across the tops of each
wave. This will result in a smoother ride.
Steer to avoid larger swells and breaking waves.
In a following sea, position your vessel on the back of a wave and match its speed to remain ahead of the trough.
Speed is paramount. Work the throttle to avoid going over the wave or being thrown down the face of a following
wave.
5.10.3 Cross-Clutching
•
World Cat’s have their twin engines mounted 60 inches apart on 250, and 270. On the 320 and 330 are
mounted 79-inch apart and the 290 are mounted 67-inch apart.
•
This allows you to cross-clutch (one motor in forward while one in reverse)
•
To dock, reverse the boat into a slip: put the outside motor in reverse and turn to face aft. Keeping the wheel
straight, steer with the inside motor putting it in forward and reverse to guide you into the slip.
•
Keep it simple and slow
5.10.4 Get the boat on plane
•
Trim both engines down or in (the motors act as trim tabs forcing the bow down)
•
Big advantage operating in shallow water (12” to 16” depending on the model)
•
Quickly increase speed to get the boat on plane then slow down to 3500 RPM’s
•
Adjust trim out until the motors cavitate then tap trim in
•
Feel/hear the motors and do not watch the trim gauges
•
A smooth ride is more important than having your engine RPM’s synchronized
5.10.5 Keep the boat level (if the seas change or people move on the boat)
•
Trim the
High-Side-High
. When one side of the bow is high compared to the horizon, simply trim the high
side motor up or out. (If it cavitates then trim the
low-side-low
)
•
Different models have different sensitivity to trim (do not over-correct as this may cause the boat to pitch in
flat calm water at high speeds)
