A good 8ft+ set wave that took the yacht out, he should have been on a surfboard not a yacht, you wouldn’t want to be in that impact zone with anything other than a IRB.
Top marks to the surfers for getting in there to help, very dodgy with all the cables trailing in the water and the boat sinking, looks like the boogie board rider gave the skipper a lift out lucky chap.
Moral of the story: If you see a load of surfers in the water in front of you, have a look over your shoulder as you are likely to be in a surf brake.
This is the legendary reef brake just outside Porthleven harbour:
