Thanks to Craig Russell of H2uh0 - Bonehead Moves on the Water for drawing our attention to this amazing video of a boating accident and the subsequent rescue attempts.
It is, of course, a reenactment, from an "informational reality-based television series" called Rescue 911 which apparently was hosted by Captain Kirk of the Starship Enterprise before he landed the gig with priceline.com that made him famous.
I am sure that my eagle-eyed readers with their wealth of boating knowledge will, like me, be cringing at the various mistakes that led to this accident and that could easily have caused a real tragedy.
It's a gorgeous early summer weekend in my part of the world that is certain to bring many boaters, experienced and novice, cautious and reckless, out on to the water.
Please feel free to contribute your wisdom in the comments.
Help boaters learn the lessons from this video.
Tell them how to play safe.
