This board had a major deck delam. between the divinycell and the eps.
My theory is that it was caused by a manufacturing defect allowing copious amounts of water to enter the board in fairly large amounts. (may have been just hard sailing, but I like my theory
). Once left in the hot sun with all the water in there it caused major expansion causing the deck to delam.
The manufacturing defect is shown on the first few pictures. The thin wood laminate on the deck was run right over a large unfilled gap just in front of the front foot strap (first pictures).
There were voids in between each footstrap insert as well. The footstrap inserts are held together by a flimsy plastic bracket to make installation fast and easy for them (also pictured). This made a direct conduit, tunnels lets say, for water into the board.
The board weighed in at 22 Lbs when I got it. I tried to dry it out by conventional means but the eps just seemed to want to hold on to the water, even with the deck fully removed. To get over the water problem I mined out the eps until there was no trace of water, just bone dry eps, and replaces it with medium density pour foam.
Finish board came in at 16lbs, which is a couple of lbs over spec, but this is my high wind board so I'm quite happy with the weight as it is.
The divinycell that I used is at least double the thickness of the divinycell jP used under the wood so I didn't bother with the wood.. plus finding a suitable veneer may have been another issue (australian pine).
Board sails well. Material were $200 to $250 plus labour if you were not to do it your self. I would only do it again if the board were free, which this one was, or a near new board that was still worth some money after the repair. ie you can buy a decent 2008 windsurf board for $350 to $450
