The Andersen 12ST is a single-speed, self-tailing manual winch in full stainless. Its drum has vertical ribs on a smooth surface, and the self-tailing arms can be set through 360 degrees. The power ratio is 9.5:1 and the gear ratio is 1.3:1. It takes line from 1/8 to 11/16 in and weighs 5.7 lb. The maker says it only needs servicing every 2 years.
Our take
The 12ST has one speed at a 9.5:1 power ratio, so there is no extra gear to shift into when a sheet loads up. Its drum grips through the shape of its ribs on a smooth surface, not a rough texture.
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.
