Yes I agree waves are never done justice on video and these are decent ones.
Went to the utube link as i really want to learn about what others do in conditions I might face one day where there are a few comments from the poster - 65 knot
winds and 34 knot
surfs were the tops. No motor
just a "drogue line" (warps?)
So reading between the lines the bare poles were probably from earlier when the wind was really up and its good to know on a cat at least it seemed very stable without any sails up in lower winds later.
Like i said not what I would have planned to do from sailing a mono in the southern ocean in similar waves but its gone in the memory banks for an option when the wind and the sea gets up on my cat one day. I know we can do 6 knots barepoles downwind in 38knots flattish water
so at around 45 knots its an option i guess.
