Winches > Use Chart

This winch use chart will give good results, but it requires that you know the exact dimensions for your boat. If you do not know your exact dimensions, use the graphs below for average dimensions for your size and type of boat, but be sure to confirm the dimensions before ordering a winch.

Rig dimensions have precise definitions under the racing rules; those shown are general descriptions only.

Whenever there is a question regarding winch selection, please contact Harken.
