Getting and Staying Trimmed
Most boats break over (or get on plane) at a particular speed. This speed is
determined by weight distribution, and water conditions, etc.. Bennett trim tabs
enable your boat to plane at speeds lower than the natural planing speed. When
tabs are deployed, your stern will rise and lower your bow, getting you up on
plane faster.
Optimum Attitude
A good way to find your boat's optimum attitude is to conduct a simple test.
Run the boat lightly loaded, at full speed on flat water. Notice the bow in
relation to the horizon. This should be your boat's best running attitude.
Properly sized trim tabs can be used to recreate this optimum attitude regardless
of weight distribution, speed or water conditions.
Getting Used to the Feel of Your Trim Tabs
When learning to use your tabs manually, begin by pressing the Helm Display
in half-second bursts for gradual trimming. Be careful not to over-trim your
boat. An over-trimmed boat will "plow" or "bow-steer". If you over-trim the
boat, simply press BOW UP and the bow of the boat will rise. For information
about operating ATP auto mode, see page 32.
