All right, I didn't watch the whole video before making the post-seems the feed is pretty slow, even with a high speed hook up.
Still and all, would you let your wife or kid ride it out in the cockpit of your C-Dory if you had the misfortune to have to come in over the entrance/bar in that stuff?---or insist they come inside?
My "training" in such matters comes at least partially from racing offshore in large keel sailboats from 35-60 or more feet in length, where dropping the sails and coming back for you is a chancy thing. With the kite (spinnaker) up and going as much as 20+ knots offshore, it may take a half a mile or more to drop the chute and turn the boat around. Try finding someone in 10 foot or more seas under those conditions! Especially at night! The man overboard marker poles have flags and strobe lights on them, but there's no guarantee the pole will be where the person is. A personal EPIRB (radio beacon) is one partial answer, but it's just easier to stay on the boat in the first place, rather than wait for the Coast Guard to pick you up in the morning.
I rode in one of the new 47 ft Coast Guard Surfboats a few years back, and Mustang work/survival suits, crash helmets, life vests, big time seat belts, and bucket chairs made with 2" aluminum tube frames were the order of the day. Guess they wanted you to stay attached to the boat in the event of a roll over! Apparently it's better to be strapped to the bridge than swimming with the props!
One of the prime rules I have always heard about survival in marine emergencies is to stay with the boat, at least until it's headed for Davey Jones Locker.
I know there are extenuating circumstances and counter arguments to all of this, but I'm still going to stay inside and keep my body mass as low as possible in my CD-22, where my feet (only) will be below the waterline.
My $0.02 on a wet, rainy night with not much else to do!
Joe.
