Andersen #34ST Self-Tailing 2 Speed Stainless Steel Winch

Power Rib™

Major Effect with Minor Effort

Get a Grip

ANDERSEN Winches™ feature the Power Rib™. Unlike other winches with abrasive drum surfaces, Andersen Winch™ drums have vertical ribs running up the surface. This combined with the smooth polished stainless steel gives a maximum grip and minimum wear on ropes, reducing the replacements costs of sheets and halyards. What’s more, the Power Rib principle simply makes sailing more pleasurable. Fewer turns on the winch make tacking easier. Sheets can be gently eased out without harsh snatching and the risks of overrides and jammed sheets are significantly reduced. The grip provided by the ribs will remain the same year after year, unlike many other winches with an abrasive or sandpaper-like surface. Such surfaces have a tendency to wear down both ropes and themselves.

It’s all about protecting your investment. With ANDERSEN Winches™, this protection is guaranteed, as the drum maintains its grip year after year. Keeping wear and tear to a minimum also helps maintain resale value, and our 3-year warranty and instant service in more than 30 countries worldwide amount to a benchmark standard.

Low maintenance is a key — and with ANDERSEN Winches™, you can take it for granted. Our winches require less maintenance, since all pawls and springs are captive, and the design of the winch allows you to strip it down for service and greasing.

Power Ratio is the mechanical advantage of the winch and is calculated as follows:

length of handle x gear ratio /radius of drum

The pull of the winch is based on the Power Ratio and not just on the physical size of the winch or the diameter of the drum. The Power Ratio is used to determine the load the winch may handle as follows: pull of handle (kg x Power Ratio = pull of winch (kg).

This means that by applying a load of 10kg, using a 10" standard handle, on a Power Ratio 40:1 winch, the winch can pull 400kg, assuming that the winch is 100% efficient. This is not possible in practice as the efficiency is reduced by internal mechanical friction losses.
