Here in my part of the country, it’s the end of another boating season. I pulled my

out yesterday and she is now sitting behind the house in her winter home. For the fifth time now I removed the cockpit cushions and had to lay them across an opened step ladder in the garage to drain them. They drain for days and days. Eventually I will remove the vinyl covers, and the foam will continue to drain for weeks. Less than that if I wring it out a few times. This is in spite of taking them each spring and wrapping the inside foam with thick, industrial strength, black plastic debris bags. I use two bags to fully wrap each large side cushion by sliding one bag over each end. I then fold the edges over to lock the open ends inside themselves, and tape up the seam in the middle with several layers of duct tape.
But still every year they get loaded with water. You don’t notice it much in everyday use. It’s not like they leak or squirt water out when you sit on them, but at the end of the season the inside foam is saturated. The outer covers are vinyl with a fleece like inner side and zippered closures. It only happens to the large seat bottoms. The helm cushion and the seat back cushions are always dry as a bone.
I thought this time I’d ask in the forum to see what others do or have done to solve this. I know I can get closed cell foam. I know I can get new cushions. But except for the water problem, the cushions are in pretty good shape. Do you have this problem? What do you do deal with it.
