This video is interesting for a lot of reasons.
Firstly, one questions the lack of skills of the sailor, in getting caught there in the first place and then not being able to simply fill one of his sails and get off.
We also marvel at the strong hull of the yacht, identified in one of the comments as an S2 8.5, a 28ft cruiser built by S2 Yachts of Holland MI in the late 70s and early 80s.
Finally, the comments make interesting reading. Yes, the rescue swimmers were brave to go in, but they actually didn't achieve anything as the boat finally comes free of its own accord.
But definitely worth watching.
