If it’s a full width sundeck you’ll probably want two hinges, one on either side. Otherwise, start with one and see how it looks and feels. Sometimes it’ll sorta sit lopsided and floppy if one isn’t enough.
Hi Tom, question, what thickness plywood do you use for the sundeck cover? Also, have you ever used a PVC plastic or king starboard for the cover of the sundeck? Having issues finding aan upholster so wondering if you did anything different then padded vinyl pads? Thanks.
Great question! I use the same 3/4" plywood that I use for the floor (PontoonStuff.com's marine grade treated). I cut it to the correct size and then my local upholsterer does the foam and the matching vinyl. The only other material I've seen was a molded plastic, likely made specifically to those boats by the manufacturer...it didn't look aftermarket!!
Usually 20# or 30#. Sometimes 40# if it’s a shorter strut. We mostly just want it to make opening a little easier and mainly to hold it open safely at the top!!
