Lewmar DC1 Single Rope Clutch | Marine Rope Clutch for Halyards & Control Lines
The Lewmar DC1 Single Rope Clutch is a compact, high-performance rope clutch engineered to provide secure, reliable holding of individual halyards, reefing lines and sail control lines on modern cruising and performance yachts. Its space-saving design allows sailors to safely lock off loaded lines, freeing the winch for other trimming tasks while maintaining positive line control.
Designed with a precision jaw mechanism, the DC1 grips rope securely under load while minimising rope wear, allowing for smooth, controlled release when adjustments are required. Manufactured from durable marine-grade materials, it is built to withstand harsh offshore conditions while delivering dependable long-term performance.
The DC1 is available in three rope size ranges to suit different applications:
- 6–8mm rope
- 8–10mm rope
- 10–12mm rope
Each model is rated with a 500kg Working Load Limit (WLL), making it suitable for a wide range of sailing yachts and performance cruising boats.
