I think it was only under for just a short time. It is getting about time to cut the floor out and rebuild it. I have a lot to read up on before I try to do it my self. Never worked with glass. But she rides like no other 17 ft cc that I have been on. I take it 9 miles off the beach in the summer to fish and fish the bay all the time. I sometimes want a bigger boat but when i go to the pump after a day of fishing and only burn 16 gals it changes my mind.
