I have been on other prindles that have flexy decks so i intend to add some bracing of some sort to support the deck more than it is now. The decks are held on by the edge only and seem to flex when stepped on. I would rather the decks feel solid and firm with little to no flex.
Check out the photo section on the Tornadocat Yahoo forum...there's a nutty Aussie rebuilding his glass T boat in his living room. He's added lots of reinforcing including deck frames and gunwale stringers.
