Thank Air, The Whalers have about the same style deck (solid/foam Cored) and I am pretty dure that is the root I am goingto go. My deck is pretty close to two inches thick (gellcoat/fiberglass/wood) So I should be all set.

If it pullls loose, I can always go back and threw bolt it to the deck..
Hopefully some more pictures to come next week
Now all I need is that leaning Post before the wife catches on
