Winches > Three-Speed & Three-Speed Self-Tailing Racing
Three-speed winches are the heart of any racing boat's winch package. They are ideal for most primary and secondary winch applications. Three-speed self-tailing winches are used as secondary and halyard winches on large racing boats and as primary winches on shorthanded racing boats. They feature hard-anodized aluminum drums and PEEK® roller bearings for exceptional weight savings.
The high-speed first gear is engaged by depressing the nameplate ring. Use first gear for fast sheet trimming in light air or ignore first gear in heavy air.
