“If those left aboard lose sight of you, there is a 40 percent chance you will never be seen again — dead or alive.”

When people fall overboard, more often than not it’s at the marina when boarding or stepping off the boat. They slip or trip and end up in the water. The surprised swimmer is usually unharmed, except perhaps for a damaged ego, and is quickly recovered and made fun of.

Fishing is another activity that sees a lot of unplanned exits from the deck. But most people fish with friends, and the wet crewman is usually quickly recovered, unharmed, and made fun of.

Fall off a vessel that’s underway, however, and everyone quits laughing, fast.

The most dangerous part of boating is an unexpected fall overboard. How dangerous? If those left aboard lose sight of you, there is a 40 percent chance you will never be seen again — dead or alive.

Read that again.

I’m not trying to take the fun out of boating, but when to wear a life jacket and what to carry in its pockets is the most important discussion I have with boaters. After a lifetime of looking for PIWs (persons in the water) and usually coming back empty, I’ve developed some rules about life jackets and their use. Follow them, and your chances of being rescued go way up.

Rule 1: Wear a life jacket with pockets

Life jackets have pockets for a reason, and it’s not to carry snacks. The best jackets have loops of webbing or tabs inside the pockets for tying in gear (I’ll come back to that). The idea is that if you don’t carry signaling gear and other survival tools in your life jacket, you won’t have them if you fall overboard. No one ever said, “I’m going over! Toss me a strobe light!”

Life jackets without pockets solve only half of your problem if you end up in the water. Sure, you have to stay above the surface to stay alive, but pockets hold gear that will solve the other part of your problem: being found.

If your PFD doesn’t have pockets (this is true of many inflatables), you can often buy them to attach to the webbing belt. If you can’t, you’ve got the wrong device. Get a new one.

Rule 2: Pack more than one thing but always pack a rescue beacon

I’m often asked what’s the one thing boaters should always carry. My first reaction is to say a life jacket with more than one thing, but if I had to pick one it would be a personal locator beacon, set up and registered correctly.

A PLB that’s activated and attached to your life jacket is the best guarantee — no matter what else happens — that someone will be in your general area looking for you. AIS can’t guarantee that; it requires other boats to be close enough to get the signal and be AIS-equipped. A handheld radio can’t guarantee that. Your cell phone definitely can’t.

Sure, PLBs cost more than most life jackets, but if you should have to activate it while you’re alone in the water, you’ll think it’s the best money you ever spent.

Rule 3: Being found is about being seen — pack signaling gear

A brightly colored life jacket can be a signal, but only during the day. You want something you can actively use to attract attention. Carry at least the following signaling gear:

  • Lights: It’s best to have a water-activated strobe attached to the upper shoulder of your vest, though keeping one in a pocket is better than not having one. At a minimum, stuff a few 12-hour chemical lights in the PFD. 
  • Signal mirror: It may seem like a last-chance survival device, but a mirror is lightweight, inexpensive and small, and it has unlimited range and never runs out of battery power. Like whistles, a mirror falls into the no-good-reason-not-to-carry-one category. Coast Guard-approved mirrors are too big (4 by 5 inches, on average) to fit into most pockets, but the sun doesn’t know the difference when it reflects off a smaller one. 
  • Waterproof flashlight: This is my favorite. I carry two. Nothing turns a helicopter around like a waving flashlight. Strobe lights have a range of about 3½ to 4 miles, but the focused beam of a strong flashlight can reach almost anything on or above the water. 

Rule 4: Make sure hands aren’t required

You will be opening pockets that are underwater, and you might be working in the dark. The gear must be tied into or onto the vest. If you drop something, it’s gone. The Coast Guard had us tie our gear in with 36-inch lengths of nylon cord. It always served me well and seemed like the correct length.

Devices such as strobes and PLBs must be securely attached as high above the water as possible. You won’t be able to hold either device for long, and just because some beacons float doesn’t mean they work well when floating. The antenna must be high to effectively transmit a signal.

Falling overboard is the most dangerous part of boating. Choose your life jacket and set it up as if you knew you were about to end up in the water. Plan on it. The gear you leave on the boat won’t be any help once you’re swimming, so—most of all­—wear that jacket.
