While I agree that the video did not go far enough...without a mention of dressing for immersion or even a reminder that without signaling equipment (or even with it) there's no guarantee that help WILL come much or less that it will come within the hour it takes for you to pass out. I guess they were going for the basics first...instead of telling boaters they should have on wetsuits (probably dry suits) on those randomly sunny and 75 degree days in Georgia in January because the water temperature is still 42 degrees they figured they may be able to talk them into life jackets. Maybe they were afraid people would write off the whole thing if they asked for too much.
I guess they're saying that there's a better chance of miraculous rescue if you have an hour than if you have a few minutes. This should have been voiced as dressed for immersion>just a pfd>no pfd instead of indicating that all is needed to survive is a pfd but their intentions were admirable and if people follow their advice then some lives will probably be saved.
