Product Information

Power Rib™

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.

Power Ratio

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.

Winch Owner’s Manual

ANDERSEN Owner’s Manuals provide important technical, user and service information regarding your ANDERSEN products. We recommend you carefully read the manual before installation and use of all ANDERSEN products. We also recommend you follow all service guidelines for your gear. With proper use, ANDERSEN products will offer years of trouble free service.

Service Kits

Regular maintenance is important for smooth and trouble-free operation of your winches. ANDERSEN Winch Service Kits use authentic factory replacement parts and include all the crucial spare parts necessary to ensure perfect performance from your winch every time.

In normal recreational use, we recommend cleaning, greasing and inspection of all moving parts every 2 years for extending winch life. Under extensive use, such as racing, charter or blue water sailing, we recommend more regular maintenance procedures; at least once every year.

Service Kits are a must for optimal maintenance of ANDERSEN Winches, as they include cruicial spar parts. Cleaning and greasing event 2 years is also necessary for extending the lifetime of your gear. www.andersenwinches.com/ox/Files/PDF/Service Kit/SERV
