Description

Lewmar windlasses are designed for reliable anchoring and docking, easing the effort for boaters. They feature robust horizontal worm motor-gearbox technology, integral contactors protected by durable maincases, and sealed waterproof units for minimum maintenance. They are engineered for quick, easy, one-piece installation and are often made with aluminum and composite maincases for reduced weight, and stainless steel warping drums with a unique 'Wear and Abrasion Reduction Pattern' finish. Many models come with reed switch and magnet fitted as standard for chain counter applications.
