RC12/10 Capstan Windlass - 24V - 3/8" Chain & 3/4" Rope
The RC12 fully automatic windlass series is designed to effortlessly retrieve and deploy 10mm (3/8") short link chain and 16mm (5/8") to 20mm (3/4") three strand or 8-Plait rope (RC12-10) and 12mm/13mm (1/2") short link chain and 20mm (3/4") three strand or 8-Plait rope (RC12-12).
With a maximum pull of 1590 kg (3500 lb), and an anchor retrieval rate of 15m/min (50ft/min), the RC12-12 is one of the fastest and gruntiest windlasses in its class.
A sleek, Low Profile version and a fluted stainless steel capstan drum version, are available.
The RC12 is packed with innovative features combined with Maxwell's traditionally classic aesthetics, but reflecting the modern form follows function of the highly successful RC6, RC8 and RC10 series windlasses.
The elegantly designed deckplate and chainpipe cover are manufactured in polished marine-grade 316 stainless steel, as are the heavy duty pressure arm, stripper, chainwheel and fluted capstan drum.
The huge, through deck hawse pipe throat ensures easy entry of the rope/chain rode into and out of the anchor locker.
Double cone-type brake/clutch mechanism permits Free Fall anchoring. Cone clutches, unlike dog clutches, provide smooth progressive engagement, ensuring safe and precise operator control.
The RC12 features Maxwell's revolutionary and Wave Design™ chainwheel.
Emergency manual retrieval is made simple and easy with Maxwell's unique Active Latch Ratchet System operation that prevents backwind of the windlass during manual hauling of the anchor.
The Maxwell-designed and innovative black, hard anodized gearbox provides numerous advantages: - Fast and easy windlass installation - More corrosion resistant - Easy to maintain and service - Takes up less room in the anchor locker - 75:1 Ratio (RC12-10) or 100:1 Ratio (RC12-12), single stage design with less moving parts, for smoother and quieter operation - Allows for multi-positioning of the gearbox/motor.
Every Maxwell automatic rope/chain windlass comes complete with all the necessary components for fully automatic dual direction control in a competitively priced package.

Installed on Yanmar 4JH57 engines with Zeus Controllers - HOLY WOW power. Losing some power at top end but overall very satisfied. Will do a long term review later. Talk about power - hope to never need my generator again!
We bought these boots in 2022, and are buying new ones 3 years later. We love the design and the fact that they are easy to remove for inspection of the rig.

Complete upgrade of my Irwin 54 Sloop electrical system –
Phase 1 – Remove 9KW generator, install 30KW LifePO4 battery system, inverter chargers, battery chargers, etc. wired for worldwide shore power capability to ABYC standards. Installation made possible with guidance and support from Andre Cormier and The Yacht Rigger.
I was amazed with the product especially, the attention to detail. I was also very pleased with the help and recommendations I received from Chris Wilcher. He made the purchase very easy.
