Engineered for Strength and Reliability

Every Muir Vertical Windlass is designed and manufactured in Tasmania, built from 316 stainless steel and precision-engineered components. Our designs focus on quiet operation, compact footprint, and uncompromising reliability.

Oversized Worm Wheel Gear
The worm gear inside Muir’s gearbox is up to 10% larger³, delivering smoother torque transfer and longer gearbox life. ³ vs equivalent power-rated competitor windlass.
SS431 Drive Shaft — 200% Stronger
~10–20% larger diameter and twice the yield strength of 316 stainless for unmatched durability in heavy-duty and commercial applications.¹² ¹ vs equivalent power-rated competitor windlasses ² vs SS316 shafts.
316 Stainless Top Works
Solid stainless construction with no plastic components for superior strength, corrosion resistance, and durability.
Quick-Fit Adaptor System
Exclusive to Muir’s 600–2200 Series windlasses, allowing faster, cleaner installation and easier servicing access.
Quick-Access Chain Pipe Cover
Quick-release design for fast clearing of tangled or jammed chain.
Muir marine gypsy — gypsy (chain wheel) close-up
Heavy-Duty Gypsy in 316 Stainless or Bronze
Designed for precise rope and chain engagement, Muir’s gypsies deliver exceptional wear resistance, quiet operation, and extended tooth life — even under heavy load.
MCOG™ — Muir Chain-Optimised Geometry
Delivers quiet, consistent chain handling and smooth feed into the chain locker.
Windlass Selection Tool
Oversized Marine-Grade Motors
30% larger-diameter heavy-duty motors with conservative power ratings deliver higher torque, cooler operation, and extended windlass life.¹ ¹ Compared to equivalent power-rated windlasses from leading competitors.
Nyllic™ / Cerakote Protection
Critical drivetrain components coated in Nyllicâ„¢ or Cerakote for exceptional corrosion resistance and service life.
Mirror-Polished 316 Stainless Steel
Precision-machined from marine-grade 316 stainless steel and hand-polished to a mirror finish for superior corrosion resistance and a Superyacht-quality shine.
Deck Isolation Pad Included
Prevents galvanic corrosion and vibration transfer between the deck and windlass base for quieter, longer-lasting performance.
Rope Chain Management System (RCMS)
Seamless transition between rope and chain retrieval for quiet, reliable operation in all anchoring conditions.
  • Flexible power configurations — available in 12V, 24V, and 48V DC, with hydraulic drive options on most models — ensuring compatibility with a wide range of vessel systems.
  • Separation of dissimilar metals prevents galvanic corrosion.
  • Self-Lubricating Bushings – Durable, low-friction bushings ensure smooth operation and reduced maintenance intervals over years of use.
  • Independent Gypsy and Capstan Operation – Enables separate or simultaneous control for flexible anchoring and mooring applications.
  • 360° Adjustable Motor Positioning – Rotatable motor design allows flexible installation and cleaner cable routing in compact spaces.
  • Suits Multiple Global Chain Standards – Compatible with a wide range of international chain sizes and pitches for seamless integration across markets.
