I have seen a couple.
I have seen a couple of F235 with a furling headsail. They seem to sail fine to me, but I have never been on one, but from a distance I couldn’t see any problems.Actually there was a boat for sale a few months ago on the 'net that had both a furling headsail and mainsail. I saw it when I was looking for a F235. (I think it was somewhere on the East Coast and I being in San Francisco I didn’t really look in buying it.) The boat had been used by a person in a wheelchair and appeared to be in excellent condition.Well furling sails are not very good for racing for most of us I think they would be fine and obviously are going to be very convenient in a lot of ways. If you wanted a furling headsail I say go for it.Good Luck.--Dan
