We found this video on Vimeo, apparently filmed on Spain’s Basque coast this month, showing a sailboat with seven aboard attempting to enter a narrow channel into the port of Zumaia.
The passage seems routine until a swell overtakes the boat and delivers a 120-degree knockdown. The boat rights, but four untethered crewmembers are washed overboard.
The raw video is more than 12 minutes long, but you can cut to the chase around the 2:30 mark and check out a slow-motion replay at about the 4:30 mark.
Near the 11-minute mark, a small powerboat whisks onto the scene and fishes the crew out of the water.
