Lewmar Series VX Windlass

Managing anchoring with a reliable machine fundamentally changes the peace of mind on board during a maneuver. The Lewmar Series VX integrates motors and gearboxes engineered to operate in aggressive saline environments, where moisture and mechanical load constantly stress the electromechanical components. An oversized or poorly installed windlass not only risks burning out the contactor, but can compromise the safety of the entire crew when they need it most.

Installing a windlass requires meticulous attention to wire sizing based on the distance from the battery and the motor's peak current draw. Ignoring voltage drops means dramatically reducing the torque available at the windlass shaft, leading to premature overheating. It is essential to verify that the gypsy is compatible with the diameter and type of chain installed, because an imprecise fit causes jumping during retrieval or irreparable damage to the chain itself.

Our technical approach focuses on preventing configuration errors. Before shipping any unit, we review your requirements to ensure no essential accessories are missing, such as a correctly sized contactor or circuit breaker matched to the nominal current draw. Our order management aims to give you reliable data on component arrival, allowing you to plan installation work without unexpected delays.

Practical Tips for Selection and Installation

• Always verify the declared maximum working load against the combined weight of the anchor and chain you will use.
• Check the wire gauge as a function of the run length from the battery to the windlass to limit voltage drop.
• Make sure the gypsy supports exactly your chain caliber, avoiding tolerances that would compromise link engagement.
• Always install a protective circuit breaker to isolate the circuit in the event of a mechanical jam or excessive strain.
• Periodically inspect the integrity of watertight seals and lubricate moving parts per the manufacturer's guidelines to resist marine corrosion.

How do I choose the right windlass power?

Power must be calculated considering the total weight of anchor and chain, plus the resistance from wind and current. A good rule of thumb is to add the anchor weight to the weight of the submerged chain, making sure the windlass maximum working load exceeds the total calculated weight.

Can I replace just the gypsy if I change chain?

Yes, this is possible, but the Series VX requires components specifically designed for that particular model. Always verify the replacement part's compatibility with the serial number of the installed unit to avoid malfunctions in the retrieval system.

What should I do if the motor turns but the chain does not come up?

The problem typically lies in the clutch, which may be loose or seized by salt. Check the tightening of the gypsy's top nut and verify that the engagement mechanism is free from oxidation or salt deposits.

Why is electrical voltage so critical?

A windlass draws heavy current at startup. If the wiring is undersized or the connections show oxidation, voltage drops and the motor loses torque, overheating rapidly to the point of total seizure or cable insulation failure.
