BOATING TIPS
Experience is the best way to determine the handling characteristics of your catamaran. Operating the boat in
multiple sea conditions and under various loads will help you predict how the boat will perform in any situation.
World Cat provides the following recommendations regarding the performance of your catamaran:
• Establish an RPM chart which details the speed and fuel consumption at various RPM levels to
achieve the most economical operation.
• Monitor fuel gauges to determine the amount of operating time remaining at a given reading.
• Determine minimum speed for effective steering in close quarters.
• Determine the turning radius required at various speeds.
• Determine the rates of acceleration and deceleration with various load conditions. Include the dis-
tance required to stop the boat at various speeds.
Use the information provided in section 6 of the
Sportfish, Cruisers, Yachts Owner’s Manual
for more informa-
tion on boat handling.
PERFORMANCE FACTORS
Proper setup and maintenance of the systems on your boat is important to ensuring proper performance, but be
aware they are not the only factors which affect it. Several things which contribute to the level of performance of your
catamaran can change between or during trips.
ENGINE EFFICIENCY
Without proper maintenance, your engine(s) will gradually lose power, resulting in a loss of speed. Use the
recommendations in the engine’s owners manual to schedule routine maintenance procedures and as a guide
for the correct RPM range for your engines. Neglecting to do so may result in loss of performance and an
increased risk of failure.
PROPELLER CONDITION
The size and condition of your prop also plays a major role in the performance of your catamaran. A damaged
prop can result in lower speeds, sudden drops in RPM, increased fuel consumption, and severe vibration while
running. Improperly sized props can cause damage to your engine as a result of exceeding the maximum or
minimum RPM levels.
WEATHER CONDITIONS
Barometric pressure and humidity can affect the output of your engines. For example, on an extremely hot and
humid day, your engine can experience as much as a 10 percent loss in horsepower. Although you should mon-
itor your engines’ performance, be aware that the weather could be a major factor in your boats performance.
