Page 3: Introduction
Introduction Lectrotab introduces an automatic leveling control system to maintain the boat on a level plane and ensure a comfortable ride. If sea conditions change, adjustments in boat speed occur, or passengers move about the boat, the automatic leveling control system utilizes built in sensors to correct the attitude of the boat to maintain the proper level. -
Page 4: How Do Trim Tabs Work
How Do Trim Tabs Work Boaters will enjoy many performance and efficiency benefits by adding Lectrotab trim tabs. Lectrotab trim tabs improve fuel efficiency, increase boat speed, accelerate shallow water planing, eliminate porpoising, and enhance the overall boating experience with a more comfortable ride. -
Page 5: Operational Overview
Control configured for 20 foot or larger boats: The auto leveling control system may be configured for boats larger than 20 feet to effectively maintain the correct boat level. For vessels over 50’ please contact Lectrotab for correct matching of ALC control to actuators and tabs. -
