Thanks Dan, you're a life-saver. As stated above, I'm buying an all-metal mast to use on this boat, so I won't really need the sail-trac. However, if you want the mast that came with the boat (which only needs the sail-trac) you can have it.

I wasn't sure what you were talking about in regards to the H16 anchor pins, so I looked up an appropriate picture from the beach-cats: Hobie 16
I think I may just try to move the shroud anchor/adjuster straight to the deck lip as you mentioned. I probably wouldn't need to bother replacing the side-bars then.
