Lectrotab began when Jere Crews, founder of Cruisair Air Conditioning, decided to design, manufacture and market an improved trim tab system in order to eliminate design flaws inherent to existing electromechanical and hydraulic-based trim tab systems. Jere had built Cruisair, the first company to offer dedicated marine air conditioning systems, from its humble beginnings in the late 1950s to a multi-million dollar internationally distributed product line.
