When Coast Guard boat crews go out to train, they like to make things as real as possible. That means that when rough weather rolls in, it’s time to go out. Station Cape Disappointment (apparently) doesn’t take a break just because their “real” is a little more real than most.
To get good at driving in the surf, you have to go out and drive in the surf. And there is nothing like a field test of the 47 foot Motor Lifeboat’s self-righting ability (minute 2:40) to let you know you’ve got some pretty solid equipment to do your job with. I don’t think it was an intentional field test, but things worked out for the crew in any case.
