AFAIK The sail of the century , Shackleton's Eliphant Is to South Georgia , did not suffer a rolling or pitch pole . Yet must have experienced many breaking waves. Remarkable how they coped , particularly at night. I expect at night they steered by the sound of waves.
I'm certainly not making light! In the video the yacht seems, not surprisingly, all over the place after it came upright and I wondered whether the skipper and/or helm was still aboard. And now had several people to rescue from back in the worst water. It clearly looked dire. And where was the videographer based?
Did they steer, or deploy a sea anchor? At that latitude there's unlikely to be reliable moonlight and they wouldn't have lamps capable of casting enough light even if they had fuel to spare.
No injuries or significant damage; photographer was on land. Bavaria 38 incident.
I'm pretty sure they steered the whole way. I'd be very surprised if they had warps and canvas suitable to construct and deploy a useful sea anchor. They did deck the entire boat with wood and canvas, and Shackleton attributed their success to that; he stated that without it the boat would have been flooded. Also, the book describes their watch-keeping system, and that implies continual steering. If they did use a sea anchor (and I don't recall them saying they did) it would have been to slow them when surfing down a wave so they didn't pitch-pole at the bottom. But I'm pretty sure they didn't use one; the constraints of working with the materials they'd salvaged from the Endurance would mitigate against it. Remember that in order to make the journey across the ice, they had stripped everything to the bare bones; even "Mr Chippy" the cat was sacrificed to save weight. A sea-anchor would have required things like chain and long warps; remember too that warps would have been of hemp or other natural fibre, so much heavier for their strength.
