20 Self-Tailing Radial All-Chrome Winch

Harken 20 Self-Tailing Radial All-Chrome Winch

The Harken 20 Self-Tailing Radial All-Chrome Winch brings Harken's proven Radial winch technology to sailors who demand reliable, low-maintenance performance. The drum's gripping surface is precisely shaped for this winch size and drum material, featuring diagonal ribs rather than textured abrasive surfaces. This design maximizes gripping power while greatly reducing line wear over time, prolonging the life of both the winch and the sheets or halyards used with it.

The built-in self-tailing mechanism enables a single crew member to quickly and easily trim or raise sails without a second hand tailing the line. This makes the winch especially valuable for short-handed sailing, coastal cruising, and bluewater passages where crew efficiency is paramount. The all-chrome construction offers a classic aesthetic and durability suited to demanding marine environments.

At 3.9 kg (8.6 lb), this compact single-speed winch accepts lines ranging from 6 mm (1/4 in) to 12 mm (1/2 in) in diameter. It mounts with five 6 mm socket-head fasteners arranged on a 110 mm fastener circle, and the 137 mm base diameter ensures a solid, secure deck installation. The 73 mm drum diameter, combined with a gear ratio of 2.76 and a power ratio of 19.20, provides mechanical advantage sufficient for everyday sail handling on cruising and racing yachts.
