Parts Desk Insights
Best use case: This winch is the right call for sport boats and performance cruiser-racers where keeping topside weight low is a priority — particularly for mast-mounted halyard winches or secondary sheet winches on smaller hulls. The single-speed design suits applications where loads are manageable and simplicity is preferred over the added mechanical advantage of a two-speed unit.
Confirm your existing winch base bolt pattern before ordering — the Size 7 has a 4-1/4" (108 mm) base diameter. If upgrading from a smaller winch, verify deck reinforcement is adequate. For heavier loads or larger sail plans, consider stepping up to a self-tailing model. Fasteners are not included; you'll need 5 × 1/4" (6 mm) countersunk screws for installation.
