Oz,

Are you sure about bolting to a stub?
I almost didn't buy my present boat because it had no visable keel
bolts. I assumed they were buryed. Being use the doing all the
maintenance on the leaking keel bolts I wasn't sure of how to take care
of the problem. My Broker laughed at me. He said my keel will never have
bolt leaks because the whole keel is part of the hull. The light finally
went on.

Keels shouldn't be bolted to fibre Glass. It is a method that was
carried over from wooded construction. When a keel bolt works on
fibreglass there is no recovery and it will only get worse until you do
maintenance. Schooner Trash can confirm this. I know it. It is a
fault racers put up with to have the option of changing keels.
