This may be the first time you have been in total command of your new
boat. Proceed slowly. Have fun but remember that the objective of the
cruise is to learn more about how your boat operates and handles. Operate
the engines at different RPMs. Try different trim angles. Monitor the
gauges. Practice backing down and turning slow speed tight corners that
simulate docking maneuvers.
6.5.2 Operating at Planing Speed
Your boat has a “planing” hull. A planing hull skims “over” the water rather
than “through” it. To do this, however, your boat first has to reach a certain
speed, called “planing speed.”
When you first accelerate from a dead stop, the trim angle of the boat
increases, causing the bow to rise and the stern to drop. If you continue to
accelerate, the boat eventually achieves plane, which means the bow slowly
drops to a more level attitude.
It is important to get on plane as soon as possible and avoid speeds that
cause the boat to plow through the water with the boat in a bow-high
attitude. A bow-high attitude obstructs your vision and limits the boat’s
handling and performance capabilities.
Once the boat is on plane, you can back the throttles off to a point where the
hull is still planing but the engines are operating at a fuel-efficient speed.
6.5.3 Trim Tabs
Your boat is equipped with a set of electro-hydraulic trim tabs. Trim tabs
help the boat get on plane by allowing you to adjust the attitude of the boat
for variables such as load, passengers, seas or wind. Under normal condi-
tions your boat does not need adjustments to the trim tabs to achieve plane.
Use the tabs at planing speeds to make minor adjustments in the fore-to-aft
and beam-to-beam angle of the boat.
To use the trim tabs:
1. Turn the “house” battery master disconnect switch to the “ON” posi-
tion.
2. On the Safety Breaker Panel, switch the Main - One circuit breaker
“ON.”
3. On the DC Control Center, switch the Systems DC Main circuit breaker
“ON,” then switch the Trim Tab Pump circuit breaker “ON.”
