This same thing happened to my 2010 wood-carbon iSonic. I bought it from new. After the first few times of use, the sanded-finish surface layer of the deck where the anti-ski lies become delaminated from its body. When I examined it in more detail, some longitudinal crack trace is identified which is exactly the same as what is described in the preceeding thread. Frankly I would say that it is a nice board that goes really fast. I hope small defects like this can be better controlled in production to make it really a great board.
