Gone Fission - that looks like a great set up. I think I am going for something like that. Does this seem like the best path- Under the gunwale/deck to the rigging channel? Can you remove the channel top without removing the console - it appears to me that you can. Also what is the best material to re-set the screws once you put it back together, silicon calk?
Keep at it, you'll find a way forward...without having to go aft!
