First, I am sorry to see that this forum is not used much. Last post appears to have been in July 2019!
I bought my 2012 GS-249 in excellent cosmetic condition. The cabin seemed like it had never been used. The past two summers I have kept the boat at inside rack storage to prevent mold & mildew, etc.
A couple months ago I took the boat out of storage. The V-Bunk cushions, etc., had deteriorated badly. Inspection revealed that the plastic lining over the foam was an extremely thin material that tears very easily. I could not believe that Glastron used such a cheap material in a boat's cabin. A lambskin condom is thicker than that!
I went out and bought some rolls of tan-colored duct tape and will attempt to re-cover the seat cushions with that. I am so upset - if I had bought the boat new and it was in warranty I would sue Glastron. I hope people will read this post.
