TW, you're the Pro here, was judgement an issue or was it just a case of "sh!t happens" ?
I ask because there isn't much "boat" showing in that first picture. Should he have been wearing a life vest, or safety line ?IMHO, I think looking at the photos leading up to the "ejection" of the Capt, the vessel is in between the breakers going in the inlet at an angle to the beach. Timing, tide, speed and wind are always a factor, and perhaps he misjudged the distance between breakers. He was familiar with this inlet.
This shows the next breaker almost laying her down, than getting stuffed into the wave to her port side, violently righting herself, at least three times.
He was riding through a washing machine. The higher up you are the more violent the pitching and rolling. Something happened in an instant, you have to fight the wheel to hold course, the boat wants to fall down the wave and it takes alot to stay on the back side and "surf" the boat into the inlet, may have to pull the throttles back, or gun them to maintain your course.
He slipped, lost his grip, standing up at the helm, the helm seats sit pretty far back. He was "riding" her in, and got snap rolled port than stbd. than stuffed, it, going from 15-20 kts. to "0". Spray has everything soaked, and he got thrown like a bullrider.
I've never seen a lifeline, or seatbelt on sportfishing vessels. Not considered "manly".. In this case a harness with some dog leash style catches, attached to the helm would have kept him at the wheel. A life jacket would have made recovery easier, but he went under the hull, and was probably hit by the port prop. I figure he was unconcious when he hit the water.
How precious life is, and how fast the SHTF.
