I agree that this was a great crossing - playing with the kids in the salon in rough seas?
So I think it was a bit tongue in cheek.
That said. It is very hard to get a good handle on the seas from video shot from above rather than at water level.
Here is a video I just created for this thread from a couple of phone videos I took from the pilothouse of a run we did from Cave Cay to Elizabeth Harbour through the Exuma Sound just two months ago.
I estimate the seas were consistently ~ six feet, with occasional eight to nines. We pounded through this head sea for six hours.
It doesn't look like much from the video - but it was draining. In fact the missus said if I did that to her again she was on the plane home! So I would say you can't get from an amateur video what it was really like.
