Cockpit cushions are a pain-in-the-aft
I agree with Al from Orange Park, Fl. In addition to his objections, most cockpit cushions are not made with closed cell foam. When it rains and your cushions are in the cockpit, they soak up water like a sponge, literally. You have to remove the covers, expose everything to the sun, recover the foam with the covers and store below where they are forever IN THE WAY. Solution: A New Zeland manufacturer fabricates one inch thick slabs of closed cell foam designed for the purpose. They will not be a perfect fit and will not cover completely each seat (but how many times do you have so many aboard that it is cheek to cheek seating all around). Two, maybe three slabs will do, do not soak up water, and store much more compactly below. AND, while my boat was on-the-hard in the Bahamas for a year, I used one closed cell foam slab to cover one of the 55 Watt Siemans solar panels (perfect fit) so batteries would not over charge. After one year of UV the slab was still in perfect condition.
