Plane Span Hull Length • Reduced Fuel consumption • Greatly improved visibility Limited Transom Space – Individual tab size
should be slightly more than 1" per foot of boat
(APPROXIMATE) • Reduced laboring of engines • Reduced wake length. (Ex: 22' boat, 24" tab per side). In situa-

Larger Planes Provide Greater Efficiency of the sides. In doing so, pressure under the tab should always use a 12" chord: All displacement
increases, providing more lift and making any given or semi-displacement hulls; All boats with a cruis-
size tab more effective. Available in 12" chord only. ing speed of less than 15 mph; All boats over
50'; All boats unusually heavy in the stern.
Running uphill (squatting) labors the engines and wastes fuel. Bennett Trim Tabs lift the stern, putting the boat on its designed running lines for
maximum speed and efficiency. They consist of a pair of stainless steel afterplanes, a hydraulic power unit, a pair of hydraulic cylinders (actuators).
