Mainsail reefing dilemma
That roller boom reefing was obsolete from start!! I have never seen anybody in the aftermarket come up with anything to make it work. Our ''72 Ranger 26 came with the hardware. A PO abandoned it and installed reef points!!
So, take the mainsail in for a couple of reef points, add purchase to the outhaul, and, maybe, consider a loose foot modification to the mainsail (As long as it is in for the reef points).
I will let others flame about your consideration of the CDI!!
