Well let's just see Ebb;

When #45 was out of the water for deck repairs, I made no special attempt to support the deck from below , took the upper skin off and crawled, walked & climbed all over her taking no special care for anything.
She didn't move flex or loose any shape or camber to the deck.

Now you guys know why we don't want you hanging around the boatyard while we work on your boat.
