The Bennington boat cover has heated the vinyl on the seat tops causing them to become brittle and crack, according to the people who will repair the seat. I need to remove a seat at a time to have it repaired. This Tritoon has the aluminum undercover and I cannot see if the seats are through bolted or screwed. Does anyone have experience with the seats to know? Next question is once I have the seat tops repaired do I need to place something to insulate the boat cover from the seat tops? I was thinking perhaps time is the culprit not the heated black boat cover. Thank you for your input definitely needed.
