And I would second Harken
as a supplier. Their customer service
is the best in the business. I pretty much default to Harken
, even if their prices are a bit higher the support you get is just so fantastic.
Using the Harken Winch Size
Chart/Calculator, requires, at most, a little bit of common sense "tuning", when using it. As if your boat/sails don't fit the I & J, or P & E dimensions on it; then you compare the area of the sail in question on your boat, to the listed sail areas on the chart, & then pick your winch size accordingly.
Were as, trying to pick a winch size, based on a sheet loading, is a good bit more complicated. And a large percentage of folks don't have the expertise in order to do it that way, correctly.
The chart I set up the link to, makes things much simpler is all I'm attempting to point out.
Bottom Line: If you're not sure as to what size winch you need, then you pick up the phone
& call Harken (or whom ever). They're happy to help
