Engineered for Strength and Reliability

Muir capstans deliver professional-level performance with refined engineering and commercial-grade durability. Ideal for docking, pot hauling, and essential line-handling tasks, each unit provides smooth, reliable torque in the harshest marine environments. The range spans compact models for smaller craft to powerful tall-drum units for heavy-duty operations—each designed to deliver decades of dependable service.

Knurled or Fluted Capstan Drum
Deep-machined knurl or flute delivers secure rope grip and smooth, controlled operation under load.
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.
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.
Nyllic™ / Cerakote Protection
Critical drivetrain components coated in Nyllicâ„¢ or Cerakote for exceptional corrosion resistance and service life.
316 Stainless Top Works
Solid stainless construction with no plastic components for superior strength, corrosion resistance, and durability.
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.
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.
Adjustable Shaft for Variable Deck Thickness
Capstan height can be easily adjusted along the shaft to suit different deck thicknesses — with optional extended shafts available for custom installations.
  • 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.
  • Flexible Mounting Options – Can be installed vertically or horizontally to suit different vessel layouts.
  • Self-Lubricating Bushings – Durable, low-friction bushings ensure smooth operation and reduced maintenance intervals over years of use.
  • Rounded gearbox housing for easier installation in compact lockers.
  • 360° Adjustable Motor Positioning – Rotatable motor design allows flexible installation and cleaner cable routing in compact spaces.
  • Separation of dissimilar metals prevents galvanic corrosion.
  • High-grade aluminium worm-drive gearbox with oil-bath lubrication for smooth, durable performance
