Sorry I can't help with dimensions, but here's pics of mine. Unfortunately the boat is long gone.

Mine was a factory option. It came with the Bimini, dodger, and camper sides/enclosures. When everything was installed, the boat was totally enclosed.
Most dodgers are custom made by canvas shops though. I think you'll have to get it custom made.

I have a reaaly good friend in the marine apolstry buisness and tops. I just thought there were some pre-made options, But the more I think about it all boats are different so you cant just make a universal dodger. I still have my old bow rail off the V so I might buy some fittings and bend my own aluminuim and make my own frame and have my buddy at PETTY marine do the cover.
