Two good sources of info. Thanks. Both mentioned the tip about threaded rod in the mount holes. I would not have thought of that. I assume Mormandeus, that you rolled your trailer out from under the boat after it was on blocks?
I got a kick out of Captnkev's comment that the C25 keel procedure ought to be about the same. Yes, it is, except for the extra 1000 pounds of keel you 25 guys handle! Y'all gotta be manly!
