"A couple of things. No board should be stored wet in a bag, especially if the weather is warm. It is a recipe for all sort of problems. And I do not think that there is nothing particularly wrong with the Cobra factory, they make great boards. A couple of years ago I bought a couple of boards from a supposedly good builder (Carbon Art) and frankly the construction quality was worse than my Starboard or RRD"
Never heard of this before in 25yrs of sailing ,always have put boards away wet or dry and i live in a hot climate. Never had a problems with boards opening up. Seen lots of CAs down here all finished really well. Did you contact CA/Starboard/etc and tell them about the problem??? or..........not. Contact the supplier first and often if there,s a problem. Name and shame campaigns tend to look a bit petty.
