the hog panel was a bit of pain, because I had to purchase a section which I think was 4x12....but a saws-all solved all......once I determined the size I simply cut it out....the eye bolts I had attached through the boat and with effort pried them open a bit to slip the panel in, then shut the small openning.......I have never taken the wings off, but I can only assume it will be easy and quick. The panel is not alot of additional weight, is 'solid' and holds a rounded shape........rounding the panel was challenging....but force works and I was lucky to have them match up evenly.....note that I have used pipe insulation along the top of the boat and along the edges of the panel.....this cushions impact and also prevents catching your clothes or body parts......one neat feature is that the deployed wings serve as great shelves while setting and retreiving dekes......after a few seasons of using salt-hay bundles I cut, I installed the grass panels last year....no fixes and primping through the season, they are very durable and take highway trailering
NOTE.....this was not my 'original' thought....rather, I got the general concept through this site under "readers rigs" some four or five years ago! I believe the gent's name was Tom French.
