My reading of the story was Bob doused both sails, so doesn't matter which one first. Fanning up from a bundle sounds radical, need a huge gust for that to happen (70+ knot?), but i think Easy Go's battens are really light, skinny 25mm alu tubes.
Also sheeting out the bundle isn't necessary in 40 knots, bare poles is enough to propel along at 4 knots or so. Sheeted in there is no way a fan up could happen, not that would have saved her. There’s still the issue of comfort and nutrition for the crew.
From our experience it doesn't take much of a blow to make cooking impossible, 35 knots and steep 5' waves would do it, maybe a gimballed stove would have been a better idea, because its cold canned food from then on. Several days of that makes life hard, but fortunately we've never gone more than 6 to 7 hours like that.
I think there are potentially similar conditions on the east coast of Aust, a 3 to 4 knot south setting current against that super storm, 70+knots southerly, there were reportedly 30 to 40' swells out there.
