With your permission, i'll offer one more option. A-231's tracks run from the chain plates to aft to the winches just inboard of the rail. I found this easy to fasten (it is a flat run). This works with my 110%, the 130% and allowed me to place a cleat Amidships.

I'll eventually add another set of tracks where your drawing shows the green line once i add a blade to the sail locker.
cheers,
