Graham, I don't feel any contradiction here! I was trying to say, earlier, that in a "yachtsman's gale", Force 6 - 8, heaving to can be a useful technique. I think we agree, though, that it's the sea state that matters, not the wind strength. A 50 knot squall in flat water can be tough sailing, but not dangerous. 30 knots of wind that is opposed by a current, putting up big steep seas, can be very dangerous.
The only time that I was knocked down in Tystie, in the South Atlantic, the wind was less than gale force, but had changed direction rapidly, and I suspect that there were some ocean currents involved as well, so that the seas became steep and confused. In such conditions, there is not one straightforward answer. Have a look at this recent account of a very similar encounter with confused seas, again with no easy answer:

In such cases, heaving to certainly isn't the answer, and in my case a drogue wouldn't have helped.
Yes I think we are on the same wavelength, David, to make a dreadful pun! Thanks for the link, it made very instructive reading. The failure of the JSD is sobering. I assume there was degradation in the warp, or the splice was faulty, or it wasn't heavy enough for the ship's displacement. Also interesting that he ran off dead downwind under bare poles afterwards without further incident, which reinforces your point.
My friend, Barry Lewis, son of the late Dr David Lewis, left Sydney mid-January for the Mediterranean, via Cape Horn and the Falklands, aboard his 13m alloy sloop, Risky Business. A cyclone came barrelling down through the Tasman to the South Island of NZ a few days later. There were 20m waves off the west coast of the South Island, but Barry was much further west, and only had 4m seas on the beam and about 35 knots of wind. He took the main down just before sunset, because he was going too fast, and continued beam reaching with just a scrap of jib. He felt perfectly secure, so went for a nap. He woke when the boat was knocked down to about 150 degrees. He didn't lose his mast but suffered some other damage and changed course for Opua which put the seas on the quarter. Risky Business must have been struck by a random, bigger sea, because, even after the knockdown, the general sea-state was quite manageable. He hadn't even considered putting out his JSD. He's now going to go via Torres Strait, because it is going to be too late for Cape Horn when he gets going again.
These borderline conditions are often the worst. If you put out the JSD every time it got windy you'd never get anywhere. Also, if the wind is free, there is a reluctance to stop the ship and heave to. I remember Tystie's knockdown in the South Atlantic, in similar circumstances. I bought a JSD because I am uncomfortable with running off alone in a rising sea, unless I am near the helm, which is impossible to do continuously on a long passage. If you run off in a rising gale without a drogue, while sleeping below, sooner or later, it seems to me, a beastie is going to get you.
So, perhaps heaving to initially makes sense, if you are short-handed, until the wave crests start coming aboard, then either run off square or deploy the JSD. (And pray the cross-seas don't get you!) But even heaving to does not guarantee anything. A friend of mine was hove-to once in a moderate gale (once again in that nasty old Tasman Sea) when his ship was struck by a huge wave. It crushed his dinghy, broke the lashed tiller, and knocked him down to about 80 degrees. Water spurted in through every closed aperture and he reckoned the ship was buried in the sea for a few minutes. But he had a strong, seaworthy ship, with small ports and solid hatches, and quickly sorted things out. (I don't like windows in a seagoing boat, but then I am an old-fashioned sailor.)
Then he ran downwind with his storm jib sheeted flat amidships to keep the head off, and every spare warp aboard trailing out astern. I have often thought about this tactic, which a number of people have used successfully, including Robin Knox-Johnston on Suhaili. I have spent some time thinking about how one could rig a similar sail on a junk rigged yacht. Perhaps the storm jib's luff could be laced to the mast and it could be hoisted on the spare halyard, with the clew led forward to the bows? It might be best to hoist it stopped with light wool, like a spinnaker, then break it out with the sheet after hoisting. It would mean going on deck in what would be nasty conditions, but any seaman has to be prepared to do that occasionally. Even junk rigs sometimes require attendance on deck. Roger Taylor kept amusing statistics about his deck sorties, labeling them voluntary or mandatory. There were a lot less of them, of course, than with any other rig. The JSD, with its significant pulling power, seems to do the job without needing this sort of sail.
There is always going to be an element of doubt about what tactics to deploy in heavy weather, and an element of luck, given the random nature of the sea, but most seaworthy boats will survive. The crew is likely to be the weak link. I am not sure these days if I am capable of coping with a serious gale at sea.
