Re: Boat cover needed
A couple of warnings about putting a cover on a pontoon boat.
1) make sure you have a "vent" space above your seat backs. My cover came down snug and rested across the tops of the seat backs on the boats (even with the center poles supporting the cover, it still rested on the tops of the seat backs on the boat). When the sun beat down on the cover and with a little wind to move the cocover slightly, the inner lining of the cover left a residue on the seat that I could never get off. This was a "sharkskin" type cover. The mark was a black residue (slightly sticky). I started to drape a couple of cheep life vests (the orange type) over the seat backs to keep the cover off the seats. This leads into the next warning...
2) Pontoons are wet, they never dry out completely (unless you don't use it for a long time). If you cover after usage without waiting a week or two you will have a mildew mess UNLESS you provide for lots of ventiliation. The life vest trick I used about let air in and out of the covered boat very well. My top was a snap on and didn't let much air move in or out without providing a path for air movement.
