The Harken 20STA is a single-speed, self-tailing radial winch with an aluminum drum. It takes line from 1/4 to 1/2 inch, and diagonal ribs on the drum add grip. The gears and pins are 17-4PH stainless steel, and the roller bearings are composite, which Harken says cuts friction under load. The base skirt snaps on and off so one person can install it. Harken notes that the 17-4PH parts need routine maintenance in saltwater.
Our take
The gears and pins in the 20STA are 17-4PH stainless, chosen for strength, and Harken's own note says that grade needs routine maintenance in saltwater. On a salt-water boat that means putting this winch on a regular service schedule.
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.
