Lee,
Del Ray in in FL. Marina Del Rey, CA does indeed have enough temperature difference between water and air to induce a vacuum inside an otherwise water-tight hull. That is why I raised the request for brainstorming assistance.
But brainstorming requires well... brains. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
A "special" thanks to Lee even though he didn't contribute any solution that would actually help with the problem. <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
Everyone missed you at Catfight this weekend!
