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.
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 p
laning 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.
Trim Tabs
Your boat is equipped with a set of 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 conditions 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. On the Safety Breaker Panel:
a. Turn the Accessory Battery master disconnect switch to the
ON position.
b. Switch the Main - One circuit breaker ON.
2. On the DC Control Center:
a. Switch the Main circuit breaker ON.
b. Switch the Trim Tabs circuit breaker ON.
3. A set of trim tabs controls are located at the helm. The controls
consist of two switches. The port switch controls the starboard tab; the
starboard switch controls the port tab. Each switch is labeled BOW UP
and BOW DOWN. Before advancing the throttles, press both switches
on the BOW UP side for 5 seconds. This lifts the trim tabs to the full up
position.
