A Skilled Swimmer Dies Because of the Current: The Spencer Korwin Paradox and Lessons for Open-Water Swimmers

On the morning of June 26, 2026, nothing seemed unusual around the Pridwin Hotel on Shelter Island, New York. The weather was beautiful, and the water in front of the dock was calm. Spencer Korwin – an amateur triathlete who once represented Team USA – left his family vacation room for a morning swim. When his wife, Carly, told hotel staff that he had not returned after several hours, his body was found under the dock. He was 38 years old, a father of two daughters. Police believe it was an accidental drowning, but the investigation remains open. Having covered open-water swimming for years, I have stood on shorelines and watched currents strong enough to push away a rescue buoy. But Korwin's story stopped me longer because it reveals a truth sports fans rarely confront: swimming ability is not proportional to outdoor water safety. Korwin was not a beginner. In 2026, he represented the United States at the Barfoot and Thompson Age-Group Triathlon World Championships in Auckland, New Zealand. His result: 36th overall in 1 hour 20 minutes 43 seconds. His swim split was 13 minutes 27 seconds, the 32nd-fastest in the field. If the sprint swim was the standard 750 meters, his pace was roughly 1 minute 47 seconds per 100 meters. That is not elite-level speed, but it is far above the average recreational swimmer. He was a true athlete in his age group. Yet that skill is part of the problem. In drowning-prevention literature, it is called the “good swimmer paradox”: a significant share of open-water drowning victims are highly competent swimmers. They do not wear life jackets, do not stay close to shore, and do not ask someone to join them. They trust their stroke and endurance. When the current begins to pull them, they do not immediately seek an escape or call for help; they swim. They swim against the current with all their trained technique. And that very technique burns oxygen faster than anything else. Around the Pridwin dock, a local boat captain described the danger: the tidal current becomes very strong when forced through a narrow passage between two bodies of water. This is the Venturi effect: when the same volume of water is compressed into a narrower space, it must move faster. The lateral pull from the tide can reach several knots per hour, enough to overwhelm even a physically strong athlete. Drowning does not begin with panic. It begins with a stroke that moves the body one meter forward, only for the current to push it two meters back. After five minutes of fighting, even the strongest swimmer loses feeling in the legs. The most haunting detail is that the weather was reported as “nothing out of the ordinary.” I have often watched tourists swim at beaches with small waves and bright sunshine, while just beneath the surface, a rip current silently pulled them away. A calm surface is never an accurate measure of what the water is doing underneath. Hazards such as eddies, underwater channels, and tidal shifts are invisible to the swimmer's eye. Korwin also swam alone. His wife only realized something was wrong after several hours, and the search began too late. In open water, the window between exhaustion and submersion can be only a few minutes. A swimming buddy, a boat, or a lifeguard watching from shore can be the difference between a disappearance and a successful rescue. The media called him a “Team USA triathlete,” a phrase that makes the public think of elite athletes. But in triathlon, age-group world championship spots belong to amateurs; the Team USA jersey is earned by finishing first in one's age group at a national qualifying event. It is a great honor, but that label did not turn a 38-year-old father into a water-survival expert. Pool-racing skill does not teach anyone how to read currents in an unfamiliar sea, nor does it give the reflex to conserve energy when the tide is pulling. In Vietnam, Spencer Korwin's story should not feel like distant sports news. Every year, many adults who swim very well in pools get into trouble at beach resorts precisely because they underestimate the power of natural water. They are used to swimming up and down a pool, where there are black lines on the bottom and walls to grab. In the ocean, there are no black lines to guide you. There are no walls to hold when cramps hit. There is only the current – continuous, cold, and tireless. The GoFundMe campaign for Spencer's family had raised more than $361,000 against a $500,000 goal in the days after the incident – a number that reflects the community's emotion. But for me, the real meaning of this death lies in three questions everyone should ask before entering unfamiliar water: Is anyone swimming with me? Have I checked the tide tables? Do I have safety equipment such as a rescue buoy? If the answer to any of those is “no,” it is better not to go in. The current will still be there, but the chance to return to your family will not always be.
