I have seen boats with a large eye-hook mounted on angle iron and bolted to, in my boat, the four keel attachment through-bolts which are accessed through the bilge. I would like to know if such hardware is available commercially, or if anybody has a creative alternative idea. Using our club external bridle hoist is cumbersome, somewhat dangerous, and time-consuming. I'm hoping there is a better way for racers who need to hoist their boats frequently to keep the hull clean.
