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. Whats 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePower Ratio\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePower Ratio is the mechanical advantage of the winch and is calculated as follows:\u003c\/p\u003e\u003cp\u003e\u003cu\u003elength of handle x gear ratio\u003c\/u\u003e\u003cbr\u003e     radius of drum\u003c\/p\u003e\u003cp\u003eThe 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).\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDrum  D: 2-3\/4\"\u003c\/li\u003e\n\u003cli\u003eBase  B: 4-3\/4\"\u003c\/li\u003e\n\u003cli\u003eHeight H: 5-1\/4\"\u003c\/li\u003e\n\u003cli\u003eLine Entry L: 1-15\/16\"\u003c\/li\u003e\n\u003cli\u003eLine Size: 1\/8-11\/16\"\u003c\/li\u003e\n\u003cli\u003eWeight: 7.0lb\u003c\/li\u003e\n\u003cli\u003eGear ratio 1st speed: 2.6 : 1\u003c\/li\u003e\n\u003cli\u003ePower ratio 1st speed: 18.8 :1\u003c\/li\u003e\n\u003c\/ul\u003e \u003c!--- cis2:m2lsl5xp ---\u003e\n\u003cp\u003eThe ANDERSEN 18 ST FS Self-Tailing Manual Single-Speed Winch is a full stainless steel sailing winch designed for sailors who want dependable sheet and halyard control with reduced rope wear. Its polished stainless steel drum and Power Rib surface provide consistent grip while helping make trimming, easing, and tacking more controlled and manageable.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eANDERSEN Power Rib technology uses vertical ribs on the winch drum instead of an abrasive surface. The ribbed design grips lines effectively while minimizing the wear that abrasive or sandpaper-like drums can cause to ropes and to the drum itself. Consistent rope engagement can help reduce the number of turns required, support smoother sail handling, and reduce the risk of overrides and jammed lines during use.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThis manual, single-speed winch is self-tailing, making it suited for sailboat applications where efficient line handling is important. The 18.8:1 first-speed Power Ratio provides mechanical advantage based on the handle length, gear ratio, and drum radius. Actual pulling force depends on applied handle load and mechanical efficiency, so the Power Ratio should be used as a reference when evaluating winch operation and load handling.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Rib drum:\u003c\/strong\u003e Vertical stainless steel ribs provide line grip while helping minimize rope and drum wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull stainless steel construction:\u003c\/strong\u003e Polished stainless steel delivers the specified material and finish for this ANDERSEN winch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-tailing design:\u003c\/strong\u003e Helps manage sheets and halyards during manual winch operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle-speed operation:\u003c\/strong\u003e Provides straightforward manual control for compatible sailing applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e18.8:1 first-speed Power Ratio:\u003c\/strong\u003e Delivers mechanical advantage based on the winch’s operating geometry and handle load.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eProduct Details:\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eBrand: ANDERSEN\u003c\/li\u003e\n\u003cli\u003eModel\/part number: RA2018010000\u003c\/li\u003e\n\u003cli\u003eProduct type: Self-tailing manual single-speed sailing winch\u003c\/li\u003e\n\u003cli\u003eLine size: 1\/8 to 11\/16 inch\u003c\/li\u003e\n\u003cli\u003eFirst-speed gear ratio: 2.6:1\u003c\/li\u003e\n\u003cli\u003eFirst-speed Power Ratio: 18.8:1\u003c\/li\u003e\n\u003cli\u003eWeight: 7.0 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cp\u003eChoose the ANDERSEN 18 ST FS when you need a polished full stainless steel self-tailing winch with Power Rib line control for practical sailing performance.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eSEO Meta Description:\u003c\/strong\u003e ANDERSEN 18 ST FS full stainless self-tailing winch with Power Rib grip, single-speed manual control, and an 18.8:1 first-speed Power Ratio.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003ePower Rib drum: Vertical stainless steel ribs provide line grip while helping minimize rope and drum wear.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFull stainless steel construction: Polished stainless steel delivers the specified material and finish for this ANDERSEN winch.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSelf-tailing design: Helps manage sheets and halyards during manual winch operation.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSingle-speed operation: Provides straightforward manual control for compatible sailing applications.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e18.8:1 first-speed Power Ratio: Delivers mechanical advantage based on the winch’s operating geometry and handle load.\u003c\/li\u003e\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eTruck Freight: No\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eOversized: No\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"ANDERSEN","offers":[{"title":"Default Title","offer_id":44881628332121,"sku":"73332","price":911.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/1818\/2489\/files\/73332XL.jpg?v=1789188913","url":"https:\/\/www.marinepartsonly.com\/products\/andersen-18-st-fs-ra2018010000-full-stainless-self-tailing-manual-single-speed-winch","provider":"Marine Parts Only","version":"1.0","type":"link"}
