Have a look on this clever idea of induction heating to remove the rusty keel bolts or nuts.

Love a new tool. Could be very handy but unlike the automotive application where you are trying to remove a nut or stud that is surrounded by metal the keel bolts are surrounded by fiberglass and wood. You might cause some serious damage. Just my 2 cents.

Interesting tool. (I have an induction range in my kitchen--it's amazing, but you need the right pots and pans.) That'll probably work on the nuts for fin keels up to about 1982-3, with a lot of smoke if somebody has gooped them... Some time asfter that, they switched to stainless steel nuts and bolts, which induction doesn't heat.
