I like that explanation. I’ve read a number of threads on reefed furled headsails and didn’t expect to experience a con I was unaware of. A deep reef on a furled headsail looks horrible and I guess they behave the way the look. A stay sail like imagine2frolic suggests is something I need to look into. The mast on my boat is way forward, unlike a cutter rig, with J=4.32m and E=5.9m; I think that I should still be able to fit a stay with a J of maybe 3m –must talk to a rigger.

This may have helped but the feeling I had at the time was that I had too much sail up to fall off; my guesstimate was even with a second reef on the main and sheeted out there would have been way too much heel. Were it not for heaving to I would have then attempted to drop the main completely.
Probably also worth mentioning that I have spent a total of 193 days on the bay sailing and often 20 knots plus; today was different due in part to the behaviour of the rig.
What I'm trying to get at is how would a 100% jib that is not furled behave; my thought is that it would have been fine. I’ve read a lot on overlapping versus non-overlapping headsails and I am still lost as to what way to go. The current boat moves well to windward with a 135% overlapping head sail in anything under 15 knots of wind; above that though I find that the 135% is too much and the furler is used for reefing – a PITA.
