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.

Nyllic™ / Cerakote Protection
Critical drivetrain components coated in Nyllic™ or Cerakote for exceptional corrosion resistance and service life.
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.
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 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.
316 Stainless Top Works
Solid stainless construction with no plastic components for superior strength, corrosion resistance, and durability.
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.
