Not entirely correct. The new wing masts on the Infusion had some problems with this from what I heard. I guess it liked to pull out of the track near the apex of the bend (pre bend). Also when I had my 21SE, I had to put an alluminum track at the top to keep the boltrope from pulling out as well as Calvert installing a 3" long fiberglass rod at the top of the boltrope to keep it in the track while raising the sail. That being said, with some of the pre-bend we run on our rigs, the boltrope can be in danger of pulling if the main is reefed down far enough in the curv of the mast and downhaul is applied. I would assume you are (or would be) using some type of "pig tail ring" to hook up top and can say from first hand experience that it actually unhooks easier than the regular main.
