Let's see if this works better
I'd be interested to know what sort of reefing systems people are using with their Ariels/Commanders - and what their experiences are.
I never use the boom roller reefing that came with the boat. When I did use it was not satisfied - but I can't remember why.
I have two sets of roller reefing on the main, one at 20% and the other at 40%. The tack is secured with two hooks, one on either side of the boom, each mounted using one of the screws that secures the boom to the gooseneck. The outhaul/quick reef for each set of reefpoints goes from a cleat at the forward end of the boom, through the inside of the boom, and out, around a cheekblock located on the boom just aft of the clew associated with the set of reefpoints (so that the pull on the clew is about 45 degrees - 70% of the force being out, and 70% of the force pulling the sail down to the boom). The line goes around the cheekblock, through the clew, and is tied back to the cheekblock (so I get 2:1 purchase).
I often use the first set of reefpoints, but have yet to be forced to go down to the second (although I would do it in thunderstorm or other violent weather).
