Another tool for anyone trying to size winches or any other
hardware for their
boat is the
Harken CompuSpec site,
http://www.harkencompuspec.com/
Select your
boat from the list (assuming it's listed), answer a few leading questions about what you want to do, and they will recommend appropriate
hardware (Harken, of course) for your application. You can also view a loading report that will give you all kinds of fascinating information -- for example, just what is the load on the sheet for your 150%
genoa in 20 knots of
wind? Or the 100%
jib in 40 knots!
For my
small boat (with a large foretriangle), they recommended 48's for the primary winches.
