Marinas are vibrant hubs of activity, offering a place to dock boats, fuel up and enjoy the beauty of the water. However, while marinas are essential for boaters, they present hidden dangers for swimmers and anglers.
“Understanding these hazards can prevent accidents and save lives,” says Tom Allen, owner of Sunset Marina on Dale Hollow Lake. “We want our guests to be aware of the risks associated with swimming and fishing near marinas, including electric shock drowning (ESD), boat traffic, fuel and chemical exposure and entanglement hazards.
Electric Shock Drowning (ESD)
One of the most significant yet least understood dangers near marinas is electric shock drowning (ESD). Many marinas have electrical systems to power boats, docks, and lighting. If electrical wiring is faulty or improperly grounded, stray electrical currents can leak into the water.
When swimmers come into contact with even a small electrical current in the water, it can cause muscle paralysis, preventing them from swimming to safety. ESD is often silent and invisible, making it even more dangerous.
Prevention Tips:
-
Never swim near marinas or docks with electrical power.
-
Marinas should regularly inspect and maintain their electrical systems.
-
If someone appears to be drowning near a marina, do NOT enter the water. Call for help immediately and turn off shore power if possible.
Boat Traffic and Propeller Injuries
Marinas are busy areas with boats constantly arriving and departing. The movement of boats creates strong currents that can pull swimmers under or make it difficult to stay afloat. Additionally, boat propellers pose a serious risk to anyone in the water.
Even when boats are moving at slow speeds, propellers can cause severe injuries or fatalities. Boaters may not see a swimmer in the water until it’s too late.
Prevention Tips:
-
Avoid swimming near marinas or boat ramps.
-
Boaters should always be on the lookout for potential hazards in the water.
-
Use designated swimming areas that are away from boat traffic.
Entanglement Hazards
Fishing near marinas can be risky due to the potential for entanglement in fishing lines, ropes, or submerged debris. Many marinas have a high concentration of dock lines, anchor chains, and other underwater obstacles.
For anglers, fishing lines and hooks can become snagged on boat propellers, dock structures, or even other fishing gear, creating dangerous situations. Swimmers who encounter these obstacles can become trapped underwater.
Prevention Tips:
-
Avoid casting fishing lines in high-traffic boating areas.
-
Be cautious of submerged ropes or debris when wading near a marina.
-
Boaters should regularly check for fishing lines tangled in their propellers before starting their engines.
While marinas are essential for boating and recreation, they are not safe places for swimming or careless fishing. The risks of electric shock drowning, boat traffic, chemical exposure, and entanglement make these areas hazardous.
To stay safe, always follow posted signs, use designated swimming areas, and take precautions when fishing near docks and boats. By being aware of these dangers, you can enjoy the water safely while avoiding potentially life-threatening situations.
