1. Amy Martich Drowns During NYC Triathlon

Swimmers competing in an open water triathlon event.

Amy Martich was a lifelong swimmer. She even lifeguarded during her summers. At 40 years old, she entered the tough New York City Triathlon in 2011.

Tragically, another competitor found her unresponsive in the water. Despite quick help, she couldn’t be saved. Her family was shocked. Amy was an excellent swimmer, and they never imagined such a risk.

This sad event shows that even skilled swimmers can face danger in open water. It’s a serious environment that demands respect.

2. Kevin Frewen’s Fatal Abalone Dive

Diver in open water searching for abalone.

Kevin Frewen, 57, loved abalone diving. In May 2016, he was diving off California’s coast with friends. While others took a break, Frewen decided to keep searching for abalone by himself.

Going alone in the ocean is a big risk. Sadly, his friends later found him without response. It’s thought he might have stayed underwater too long, which could have led to a medical emergency like a heart attack.

Frewen was very fit. He ran daily and coached wrestling. But toughness in open water isn’t about pushing limits. It’s about knowing when to rest and always having a buddy. Safety should always come first.

3. WWE Star Shad Gaspard’s Tragic Rip Current Death

Shad Gaspard, Former WWE Star, Found Dead

In 2020, tragedy struck at Venice Beach, California. Shad Gaspard, a well-known professional WWE wrestler, was enjoying a swim with his 10-year-old son, Aryeh.

A dangerous rip current suddenly pulled them both. Lifeguards bravely rescued Aryeh. However, despite their efforts, they couldn’t save Gaspard in time.

It’s a heartbreaking reminder that even a fun day at the beach can turn dangerous quickly. Rip currents are powerful, and this incident shows that anyone, no matter how strong, can be at risk.

4. Dylan Ramsay: The Peril of Cold Water Shock

Dylan Ramsay's Story

A hot summer day in 2011 led 13-year-old Dylan Ramsay to seek a cool swim in Hilltop Quarry. Tragically, he was later found dead at the scene.

Dylan’s mother remembers him as a strong swimmer and an athletic boy. She now works to educate others about a little-known danger: cold water shock. It’s believed this is what happened to Dylan.

Cold water shock can happen when you jump into water that’s much colder than the air. It can make your heart race and even cause a heart attack. Dylan’s story is a sad warning about this hidden risk.

5. The 1916 Jersey Shore Shark Attacks

The Jersey Shore Shark Attack

Back in the summer of 1916, a series of terrifying events unfolded along the Jersey Shore. The first victim was Charles Vansant, 28, who was enjoying a swim at Beach Haven.

People heard screams, initially thinking he was playing with a dog. But a shark had attacked him, severely injuring his leg. Sadly, he later died from blood loss.

Over just 12 days in June and July that year, three more people were attacked. In total, four people died, and one was injured. Experts believe great white sharks or bull sharks were responsible. It’s a stark reminder that we share the ocean with powerful predators.

6. Irene Chan’s Unexpected Sea Lion Encounter

SEA LION ATTACK: Sea Lion Attacks Female Swimmer At San Francisco's Aquatic Park

Irene Chan was a regular open water swimmer at Aquatic Park in San Francisco for three decades. But in 2018, one of her swims took a frightening turn.

While swimming, a sea lion approached her from below. Suddenly, it bit her on the knee. Irene survived the attack, but it was a close call.

If the bite had hit a major artery or tendon, the outcome could have been much worse. This incident shows that even animals that look cute and harmless can be unpredictable and dangerous in their wild habitat.

7. Fran Crippen: Elite Swimmer Lost in Open Water Race

U.S. Swimmer Fran Crippen Dies

Fran Crippen, a 26-year-old member of the U.S. National Swimming Team, was a top athlete. In 2010, he was competing in an open water race in the United Arab Emirates.

Earlier that day, he mentioned to his coach that he wasn’t feeling his best but chose to race anyway. After all other swimmers finished, Crippen was still missing.

Fellow swimmers searched and found him unconscious near the final buoy. The water was very warm, around 80°F (26.7°C), and many felt heat exhaustion. It’s believed Fran pushed himself too hard and drowned. This tragedy highlights that even elite swimmers must listen to their bodies, especially in demanding open water conditions.

8. Santhosh Heddese and the Kipu Falls Current

Hawaii Falls Have Deadly Side

While vacationing in Hawaii in June 2011, Santhosh Heddesse, 35, visited Kipu Falls. This picturesque swimming hole on Kauai was a popular spot for tourists.

Heddesse jumped into the water to cool off. However, a strong, unseen current pulled him under. He struggled but couldn’t make it back to safety.

Sadly, he drowned and was found an hour later. His death was one of five at that same spot in the five years prior, raising concerns about a possible dangerous whirlpool or undertow. It’s a caution that even beautiful, popular spots can have hidden dangers.

9. George Wendt’s Shocking Drowning at Swim Event

Swimmers in an organized open water race.

George Wendt was a 73-year-old high school teacher and a passionate lifelong swimmer. On September 11, 2021, he participated in the Big Shoulders Open Water Classic, a well-known event.

During the race, around the 800-meter mark, Wendt was found unresponsive in the water. He was rushed to a local hospital but was pronounced dead.

His death, ruled an accidental drowning, was a shock to everyone. Wendt was president of the Chicago Masters Swim Club and a Hall of Fame swimmer at his high school. His story is a sobering lesson: open water can be perilous for anyone, regardless of experience or skill.

10. Bethany Hamilton’s Inspiring Survival from Shark Attack

Bethany Hamilton: Shark Attack--The Real Story

Bethany Hamilton’s story of survival is known worldwide, thanks to movies and books. On Halloween in 2003, 13-year-old Bethany was surfing with a friend at Tunnels Beach, Kauai.

While resting on her surfboard, a tiger shark attacked, biting off her left arm. She lost a massive amount of blood and was incredibly close to death. Quick action by those around her saved her life.

Bethany was already a talented young surfer. Amazingly, her spirit wasn’t broken. She returned to surfing and continues to inspire many. While her type of attack is rare, it’s a powerful reminder that sharks are part of the ocean environment. Always stay alert when in their home.

These ten stories, each tragic in its own way, paint a vivid picture of the unpredictable nature of open water. From strong currents and cold shock to unexpected wildlife encounters and the limits of human endurance, the dangers are real, even for the most experienced. While the allure of a swim in a lake, river, or ocean is undeniable, these incidents remind us to always prioritize safety, be aware of our surroundings, and respect the power of the water.
