Lewmar CPX1 Vertical Windlass 12v Gypsy Only – 1/4″ G40 Chain 1/2″ Line
Powering ground tackle on 25–35ft cruisers, the Lewmar CPX1 generates 1000 lbs of maximum pull from a 12V 500W motor, driving 1/4″ G40 chain through a compact vertical profile.
- 1000lb maximum pull recovers anchor rodes.
- 500W motor draws 35A average current.
- 90mm low-profile height clears deck space.
- 316 stainless steel resists seawater wash.
- Controlled free-fall clutch allows smooth drops.
TheLewmar CPX1combines a 500W continuous-duty 12V DC motor with a low-profile vertical gypsy-only arrangement. The windlass has a stated maximum pull of 1,000 lbs and a 250 lbs continuous working-load rating. Its precision-cast 316 stainless steel housing and high-tensile shaft support the drive system for 1/4 in G40 chain and 1/2 in rope.
The gypsy accepts 1/2 in three-strand or 8-plait rope with the listed 1/4 in G40 chain. A controlled free-fall cone clutch provides the listed release function, and the manual override provides a separate manual-control option. The provided product data does not confirm an anchor, rode, switch, contactor, or circuit breaker as included.
Which Boats This Windlass Fits
The CPX1 vertical windlass is recommended for boats from 25 to 35 ft. Its gypsy requires 1/4 in G40 chain with 1/2 in three-strand or 8-plait rope. Both the chain and rope must match the confirmed dimensions because the gypsy handles the connected sections of the anchor rode.
the listed maximum pull is 1,000 lbs, while the 250 lbs working-load rating identifies the continuous hauling value. The two ratings do not describe the same operating condition. The continuous figure provides the relevant reference for regular retrieval assessment.
Care and Operating Notes
Rinse the exposed housing, gypsy, chain, and rope with fresh water after saltwater exposure. Remove salt, sand, mud, and debris from the rope-to-chain transition and cone clutch area before operation. Inspect chain links, rope condition, manual override access, visible fasteners, and electrical connections before departure. Follow the manufacturer manual for lubricant selection, service intervals, disassembly, and approved replacement parts.
Warranty and Support
The CPX1 carries a 3-year limited manufacturer warranty. The provided warranty term does not define coverage for labor, corrosion, electrical accessories, shipping, or other components. These terms reflect manufacturer-stated coverage, and buyers should verify active warranty policies directly with the seller or manufacturer prior to purchase.
Before Ordering
Confirm that your anchor rode combines 1/4 in G40 chain with 1/2 in three-strand or 8-plait rope. You should compare your boat with the 25 to 35 ft application guide, measure deck thickness against the 0.8 to 1.6 in range, and reserve space for the 90 mm-high deck unit and below-deck drive assembly. Verify that your 12V electrical system supports the listed 35A average draw and required 50A circuit breaker. Confirm controls, circuit protection hardware, anchor, chain, and rope with the seller because the provided product data does not confirm them as included.
