[Public-List] Surveying older boats? Determining if they are seaworthy...

Randy -
I've have my 1962 Pearson Triton surveyed. It was an interesting experience:
"Hmm, blisters. If I didn't see a few on a boat this old I'd be suspicious"
"Encapsulated ballast - don't have to worry about that as much as those fin keel wonders"
In general, the surveyor was more attentive to thru-hull penetrations, especially the shaft, rigging, deck and deck fittings, and the engine installation. I'd be more concerned if I had soft spots on the deck.
Regards
Hans Thomas
