How to tell if you're on a collision course... for real !

A few months ago, a salty "sea captain" by the name of Andrew "ole one-eye" Flanagan (arrrg matey!) posted up a tasty video claiming he could spot a collision course just by looking at the movement of the other boat. Avast, his claims are debunked in this hearty video posted by Sivad the Dog Trainer!! Ahoy and enjoy matey! ;-)
