Cold Water Boating
January 2026 Recreational Boating Safety Message
By Scott Szczepaniak, Recreational Boating Safety Specialist,

After 10 minutes, with the heater of the truck running at full blast, his shaking started to subside. He was not able to speak since it happened. I was relieved that he seemed on the mend and started to relax. He finally said to me, not making eye contact, “…that it felt like a major league baseball player hit me in the chest with a fencepost.”
Long story short, my new acquaintance had joined a group of kayakers for a New Year’s Day paddle on Lake Marion in the center of South Carolina. The air temperature was in the balmy mid 70s, the water temperature in the mid-40s The paddler was in his mid-30s, super fit and ready to join the group for a fitness paddle in his surf ski. As he prepared to launch - the group leaders said “no way - you are not going to paddle with us without a life jacket properly fitted and zipped up. He reluctantly put his life jacket on. The rest of the group, all dressed for immersion in drysuits or windproof paddling jackets with wetsuits underneath to insulate, should have been more forceful about lending him a wetsuit top and paddling jacket.
The group had a nice paddle and was almost back to the landing. The paddler on the surf ski, dressed in shorts and a t-shirt, capsize just ahead of the group. The more experienced paddlers preformed a quick rescue and got him back to the landing. I helped him to his truck, got it running and turned the heat on. After he gave me his baseball player / fencepost analogy, he was quiet for a few more minutes. He then said — “If I wasn’t wearing a life jacket, and you didn’t get me out of the water so quickly, I would be dead now.” I am pretty sure that he was correct.
Cold water kills. Often not by lowering the bodies core temperature (hypothermia), but by cold shock. From the Cold Water Safety website:
“"The sudden lowering of skin temperature on immersion in cold water represents one of the most profound stimuli that the body can encounter.” -Golden and Tipton in Essentials of Sea Survival
Translation: Short of being hit by a bus or struck by lightning, cold shock is one of the biggest jolts that your body can experience.”
When you hit the cold water against unprotected skin you gasp - really gasp, and suck water into your lungs. More from the Cold Water Safety website: “Sudden Drowning - If your head is underwater when you gasp, you will immediately drown, and without the support of a PFD, you will head straight for the bottom. Before cold shock was identified as the cause, this phenomenon was known as Sudden Disappearance Syndrome.”
My friend Jack Doty fell out of his powerboat into 39º water and miraculously survived. Check out a video of his rescue here - https://www.facebook.com/watch/?v=1042131898058043
As a boating safety professional, I worry on days in the winter and spring when the air temperature gets warm enough to wear shorts and a t-shirt. The water temperature takes many weeks to follow warming trends… and is not impacted at all for those few balmy days in the winter and spring months. Whether paddling a kayak, canoe or Stand Up Paddleboard; or duck hunting in a small boat; or boating out on cold water - dress for immersion. Wear a life jacket properly fitted and zipped up. Save the alcohol for after the outing. Slow down - maintaining a safe speed is required by the rules of the road and the mark of a competent boater. Take a boating class or paddling class. Be weather aware. File a float plan as simple as a text to a trusted friend or family member that includes who, what, where, and when you are going to be back with an emergency number to call at a specified time. And include a picture of the boat in the float plan.

Boat and Paddle Responsibly! And finally, please share this post on your personal page and boating groups that you are a member of. Thanks!
