Manuals

The Harken Radial size 20 is a self-tailing manual winch in bronze with a plain-top configuration. It runs in one speed, with a power ratio of 19.2 and a gear ratio of 2.76. The drum is 73 mm across and the base is 137 mm. It takes line up to 12 mm and weighs 3.9 kg.

Our take

A power ratio of 19.2 in one speed sets what this winch can do: there is no second speed to drop into when the load builds, and 12 mm is the largest line it takes. At 3.9 kg in bronze, it is a solid piece of hardware.

From our buying guide

A winch's size number sits close to its top power ratio, though not exactly, and first-gear ratios vary more between brands. Each maker publishes its own sizing chart, so use the chart from the maker you're buying.

Check before you buy:

  • It fits your existing holes, since same-size winches from different makers need not share a bolt circle.
  • The self-tailing jaws take your rope, since they have a range.
  • You have the right bolts. Harken does not supply them, and the makers disagree about countersunk heads.
