Lewmar DC1 Double Rope Clutch | Dual Halyard & Control Line Clutch
The Lewmar DC1 Double Rope Clutch is a compact, high-performance dual rope clutch designed to securely control two halyards, reefing lines, or sail control lines from a single deck-mounted unit. Ideal for modern cruising yachts, trailer yachts, and performance sailboats, the DC1 Double provides reliable line holding while freeing your winch for additional trimming and sail handling tasks.
Featuring two independently operated clutches, the DC1 Double allows each rope to be locked or released separately, giving sailors precise control without increasing cockpit clutter. Its precision-engineered jaw mechanism grips loaded lines securely while minimising rope wear and allowing smooth, controlled release when adjustments are required.
Manufactured from durable marine-grade materials with a low-profile design, the Lewmar DC1 Double is built to withstand harsh offshore conditions while integrating neatly with modern deck layouts. It is available in three rope size options to suit a wide range of yachts:
- 6–8mm rope
- 8–10mm rope
- 10–12mm rope
Each version has a 500kg Working Load Limit (WLL), making it suitable for halyards, reefing systems and sail control applications on cruising and performance yachts.
