New trim tabs

Volvo has developed trim tab technology based on a system adapted from high-speed ferries and hydrofoils unlike any other trim system you have seen.

Designed for vessels up to 50-feet in length and speeds up to 50 knots, the Volvo QL Boat Trim System uses a series of "blades" aligned vertically, not horizontally, like traditional tabs. These blades come down in the water when activated, creating enough force to raise the stern and lower the bow.

The blades are mounted in what Volvo calls "interceptors" mounted on the transom that are actuated electronically, not by hydraulics. Made of composite material and sealed for life, the interceptors are virtually corrosion and maintenance free according to Volvo. To reduce risk of damage and to minimize marine growth, the blades automatically retract into the interceptor when the engine is turned off.

Volvo says the system has all the same performance qualities of conventional trim tabs but with a quicker, "instantaneous" response, less resistance, simpler installation and low maintenance. Mounting an interceptor requires one hole through the hull for electrical connections.

Instead of having two "up" and "down" rocker switches, the QL's push-button pictograph control panel has easy to understand directional arrows and trim indicators.

QL is available at Volvo Penta dealers and select marine retailers. For more information, go to QLmarine.com.
