Product Description

The patented Quattro is an innovative all-in-one winch used on boats that require extremely fast winches to handle large asymmetrical spinnakers, but also need power to trim the genoa upwind.

Radial Quattro winches are offered in lightweight aluminum alloy and feature composite self-tailing jaws and skirt to save weight. High-strength composite roller bearings reduce friction under load and don't require lubrication. Load-carrying gears and pins are 17-4PH stainless steel for strength and durability.

The Quattro features two drum diameters and four line speeds. The upper drum features Harken's new shaped radial grip for reduced sheet wear and controlled easing. The wide-diameter lower drum has a sand-blasted gripping surface used for fast trimming.
