If you look at a photo in my gallery, you will see that a sundeck was added to the entire bow area.
I will try to shoot some photos this weekend to show you how the supports and marine ply structure were made for the cusions. The whole thing lifts out in three sections, so you can go from sunning to fishing mode in a couple of minutes.
Construction will be slightly different in the Osprey as compared to my CCP but the basic idea should still work.
