Re: 1990s Coastal Cruisers vs. Mid 70s Bluewater Boats
Valiants are a special case...they have blisters in that area that are NOT osmotic, but due to the resin not kicking with the glass. Im hardpressed to believe that these blisters wont become structural at some point. THat being said, many a "pimple" valiant is out there which is a testament to how well they're built. Most bluewater cruiers even from the 70s ear (now 40+ years ago...wow) are not going to be in the $50k range. $100k perhaps.
I hope $50k isn't your end budget. Even a modern coastal cruiser in the $50k range is going to need a HELLOVA lot of work to get into shape for crossing the pond. Rigging, chainplates, electronics, and general "beefing up".
