That guy was lucky. He made it out. If he had been in PNW water the outcome could have been very different.
I have been caught in big (8 foot +/- ) following seas one time. It was in Georgia Strait, and we were heading to Princess Louisa after launching in West Vancouver. Seemed like hours, but really about 2, and they were off the aft port quarter. We did a lot of surfing, having to angle to port to avoid the lee shore. There were a few occasions of "bow steering" and I can assure you, that is NOT comfortable. My best result were to power up and turn into the wave ahead, so away from the direction the boat is trying to self steer. These were big waves, and 3-4 boat lengths between, with about half of them breaking to whitecaps. Not my most pleasant "boat ride" but I was never afraid the boat was in danger of a broach.
In big waves, I prefer to be going into themm not running with, or from them. In those situations I have buried the bow several times. I have had green water up to the dog house curve and up and over the forward hatch a couple of times, and the C-Dory does pop up fast. I have buried the anchor many times, with no untoward after effects. It has to do with the short coupled, steep waves, usually crossing a tide rip. On one occasion, running down Knight Inlet along side a CD25 for a couple hours, in 3 to 5 foot on coming waves, I think I probably stffed the nose 2 or 3 times as often as the 25 did.
Mind you, these are not times and places I decided to just go out and see how far into a wave I can stick my bow, but where, conditions changed. They are all doable, and illustrate that the boat can handle much tougher water than the crew in most cases. I think there are huge advantages to our "flat bottom" boats with a closeable cabin. If that guy in the video had been on a C-Dory, he could have powered right through those waves, providing he had the hatches and windows closed.
