I just discovered a new, rather large crack in mine. As expected GW has stepped up and has a fix plan in the works. They truly have THE BEST customer service in the industry. For those who question the price of top tier boats, at least for GW there is great value for the money.
They have made some changes to allow for expansion/contraction in the headliner. This is one of those issues that just isn't known until a few years in the field. While it would be best to never have the problem, I am very happy that GW takes care of their owners well past the warranty period.
I suggest contacting your dealer or

On a side note: my new u/w lights ROCK!!!
