I have previously rebuilt a 70's T that was in similar condition. I would NEVER do it again!
I subsequently built a new wood T from plans, and that was (and is) far easier (and possibly cheaper in the long term) than trying to get an old, soft, disintegrating boat right. If it was in the UK, that boat would be for scrap only - if you could find a buyer though, it'd be a rip-off at anything over a couple of hundred pounds. <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" />
