5.4 Steering Controls
Catamarans offer unsurpassed steering control. The wide spacing of the engines, advanced steering
components, and handling characteristics of the World Cat hull give operators exceptional maneuverability
in even the tightest spaces.
Because of the superior tracking abilities of the World Cat hull, over-steering 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 resist the urge to make constant corrections.
5.5 Steering Maintenance - Twin Engines
The design of a catamaran hull requires a special steering system which features a “liquid tie-bar”, as
opposed to the mechanical version used in conventional boats. For this reason your World Cat is equipped
with a hydraulic steering system, featuring steering cylinders mounted on each engine and a steering system
valve. This system enables both engines to respond in unison to adjustments at the helm.
In order to maintain the excellent steering characteristics of your boat, occasionally you will need to adjust
the steering system to realign the motors (known as motor toe). To do so, follow these instructions:
• Using the helm, center the starboard motor.
• Find the steering system valve, located under the inspection port on the center of the transom.
• Open the valve by rotating it 90 degrees (the handle will be parallel to the valve body when
open). This will isolate the port engine, so that it can be adjusted manually.
• Center the port motor manually; then close the steering system ball valve and reinstall the
inspection port.
Similar to hydraulic braking systems in an automobile, it may become necessary to bleed the steering system
occasionally to remove air from the lines. We have provided diagrams of the steering system in section 5.6
and 5.7, and the Teleflex™ owner’s manual in your Owner’s Portfolio. Use these resources, and your dealer,
to keep the steering system in excellent working order. Be aware, these are routine maintenance procedures
and are not covered under warranty by World Cat.
!!! CAUTION
Routinely check hydraulic fluid levels and all connections for leaks or any sign of mechanical failure.
Lubricate all mechanical parts at least annually with high quality marine grease. Failure to do so may
result in impaired or unresponsive steering.
