I am thinking about trying to route my line down the starboard side instead of the port side as you did. I have a chart plotter mounted on the port side that may be a bit close for comfort when pulling the furling line.
Do you recall anything from your experience that would indicate this would be a bad idea? Sorry if there is something obvious that would indicate so (like interference with the main sheet), I'm waiting on a parts order and haven't went out to the boat and looked and thought hard on the subject yet.
Two things come to mind. If you have the sheet connected to both cockpits (2:1), then the furling line will cross the sheet somewhere and will wear on each other. Also, you might increase the chances of tangles due to proximity of the two lines.
I would give it a try, the check blocks are about ten and the cam cleat is twenty, so sixty or so for materials (need SS bolts & locknuts), and about a hour to install.
I stopped leaving the furling line on the mast, it stays on the boat all the time. It adds less moisture to the sail bag, dries out faster, and after tying a simple bowline, I'm ready to sail
