Thursday evening, a 16-foot john boat took on water with two passengers out duck hunting in North Myrtle Beach. Crews are still looking for Tyler Doyle, a 23-year-old man from Loris, SC.

Here are the answers to some questions you might have about the situation.

Here’s what we know about the missing boater. Crews are looking for Tyler Doyle.

What is a jetty?

Jetties are rock structures that provide a protected passage into and out of the ocean. Designed to reduce the waves coming into an inlet, jetties stick out into the ocean, like boardwalks.

The area where the one boater was rescued is the Little River Inlet jetty. This is where the Atlantic Ocean meets the Little River Inlet, which connects to the Intracoastal Waterway.

What is a jon boat?

Jon boats (also written johnboat) are flat bottomed boats generally made from aluminum, designed to maneuver in shallow, calm water. Anglers or hunters can use them with a small motor.

The 16-foot vessel that went missing is an average size, says Cameron Sebastian, operations manager for the Little River Fishing Fleet.

Are jon boats safe?

Jon boats can become dangerous in windy weather or choppy waters. The bow-less design of the jon boat means water can easily enter the vessel.

With a jon boat, “if you take it down post past the jetties, the danger levels increase greatly,” Sebastian warned.

The warm clothing boaters wear in chilly winter evenings can become hazardous when a person enters the water.

“Even a great swimmer, with that type of clothing on, can become over labored or overworked in a short amount of time,” Sebastian said.
