Trim Tabs - Regal 42 Fly-Grande Coupe Owner's Manual

TRIM TABS

Trim tabs are installed on the lower hull at the transom
area. Water is de ected and redirected as the trim tabs
are raised and lowered from the dash switches.
change in water ow creates upper pressure under the
tabs, and raises the stern. When the stern rises, the bow
is lowered. Lowering the port tab will cause the port
stern to rise, making the starboard bow lower. Lowering
the starboard tab will cause the starboard stern to rise,
making the port bow lower.
Using trim tabs will compensate for uneven weight
distribution, listing, water conditions, wind velocity and
other factors that cause ine cient operation.

Obtaining A Trimmed Position-Manual Operation
Your Regal yacht reaches a planing position at a designated
speed. is speed is determined by bottom design, weight
distribution, water conditions, and on board equipment.
As the throttle is advanced the stern squats and the bow
rises initially. e trim tabs allow your boat to plane at a
slower speed than natural conditions allow.
In short bursts push both trim tab rocker switches
simultaneously in the "bow down" position which causes
the trim tabs to move down. As the boat breaks over the
bow high attitude the boat speed accelerates and visibility
increases. e LED indicators will show you relative
position of both tabs and the LED light intensity can be
adjusted.
If the boat is over trimmed, it will plow the bow and
the boat will lose maneuverability. If this occurs, simply
short burst the "bow up" trim tab rocker switches
simultaneously.
