It shows you that it doesn't matter what size is your boat .Freaky waves can appear out of nowhere, even in inner harbours.I've experinced that a few times being airborne and luckily landing level . What I don't understand is ,why he wore a safety harness ,beside the kill switch? In case of capsizing there's a better chance for one to escape swimming out if still conscious.Since they have escape hatches on the bottom of offshore cats ,many people survive crashes.
