That is spooky.
He doesn't fall out of the flybridge during the broach but immediately after, probably as the boat is pitching back.
You can see him hanging on to the gunwale for about 3-4 shots and then just can't hold on.
Not too many skippers with a boat like that think about wearing a pfd full time and clipping in.
However, it does make me think about whether a seat belt used just for this kind of bar clearing is not a good idea.
I wouldn't have thought about it. But as a 61 year old charter captain
, I'll give him the benefit of the doubt on seamanship. Sometimes snot happens.
It is also not clear to me if the surf is passing the boat or vis versa.
