Hydrotab’s New Composite 300SR Trim Tabs

New Composite 300SR Trim Tabs Test

This test was performed by our Greeks friends at e-Ribbing with a SeaFighter powered bij twin 350 Suzukis.

The Rigid Inflatable Boat (RIB) maintained a slower speed while resting on the plane, with its bow noticeably lower, all without a significant increase in fuel consumption.

Reducing the new composite 300SR trim tabs by 50%, they observed a 3-second reduction in planning time with minimal bow elevation during takeoff.

Following this, they concentrated on recordings during low cruise speeds, typical for most of a daily travel. Maintaining the engine trim at a constant 40%, they began to experiment with the placement of the vertical 300SR trim tabs.

It became evident that with the trim tabs fully raised, the bow consistently assumed a significantly high position, making it impossible to achieve a satisfactory cruise within the 15 to 25-knot range.
