Why a good swimmer can still drown in open water: The death of an American triathlete in Long Island

Spencer Korwin, 38, who represented the United States at the 2026 Age-Group Triathlon World Championships, was found dead under the dock of the Pridwin Hotel in Long Island, New York, after a morning swim during a family vacation. His wife, Carly, alerted hotel staff after he failed to return for several hours. Police say the death is believed to be an accidental drowning, and the investigation remains ongoing. Korwin was no stranger to water. In 2026, he competed for the U.S. at the Barfoot and Thompson Age-Group Triathlon World Championships in Auckland, New Zealand. He finished 36th overall in 1:20:43, with a swim split of 13:27 — the 32nd-fastest among the field. If measured over the standard sprint distance of 750 meters, that pace equates to roughly 1:47 per 100 meters. It is not an elite mark, but it is a solid indicator of a genuinely skilled, well-trained swimmer, not a novice. This is why his death presents a familiar paradox in water-safety circles: why does a good swimmer still drown? Global drowning statistics consistently show that a substantial share of victims are people who can swim, sometimes very well. The mechanism lies not in technique but in environment. A pool and open water are two different worlds. The site of the incident is near the Pridwin Hotel pier, a coastal resort area. An experienced master mariner familiar with the region described the current as becoming very strong in a narrow passage where the tide flows. This is a hazard many open-water swimmers underestimate. When the tide rises or falls, an entire body of water is forced through a confined space, causing the current to accelerate abruptly. It resembles wind accelerating through a mountain gap. The surface can look calm from afar, but underneath there is a powerful push toward open sea or shore. The weather that morning was described as "nothing out of the ordinary." That is an important confounding factor. Swimmers tend to judge danger by big waves, strong wind, or rain. But a strong tidal current in a narrow channel can exist even in beautiful weather. It creates no visible noise or whitecaps. It simply moves a body outward, and a swimmer slowly exhausts energy trying to swim back. A second factor increased the risk: Korwin was swimming alone. His wife said he left the hotel for a morning swim and did not return for hours. Only after a long absence did the family begin searching and notify hotel staff. That lost window is a blind spot in every drowning case. Had someone swum with him, or had he worn a GPS tracker, the response time could have been significantly shortened. But in open water, swimming alone is a gamble. There is also the possibility of cold-water shock. On a morning in Long Island Sound, especially during a seasonal transition, the water temperature is often far lower than the air temperature. When the body is suddenly immersed, an uncontrollable gasp reflex can cause water inhalation within the first seconds. The heart works harder. Muscles tighten. For a technically sound swimmer, this may not prove fatal immediately, but when combined with a strong current, it creates a cascade of events that is hard to escape. Data from similar accidents reveals a repeating pattern: the victim is usually a middle-aged man in good physical shape, with some background in recreational or semi-competitive sports, often swimming alone in a familiar or semi-familiar body of water. Spencer Korwin — a 38-year-old former triathlete, father of two, on vacation with his family — fits squarely into the demographic that drowning-prevention programs warn about most. He was not reckless in the ordinary sense; he just may not have anticipated how much the environment had changed since his years of high-level competition. The GoFundMe page set up by family and friends to support Korwin's wife and two daughters quickly surpassed $361,000, well on its way to the $500,000 goal. That partly reflects his standing in the American amateur sports community, where "work-and-train" athletes form tight bonds through weekend races and group workouts. The lesson from this case is not that people should avoid open-water swimming. It is that swimmers must respect basic safety rules: check tide tables, avoid narrow tidal passages, swim with a partner, use tow floats or personal locator devices, and never confuse feeling strong in a pool with safety in a natural current. Swimming technique cannot defeat a tidal stream pushing an entire water volume through a gap. One question investigators will have to answer is whether a medical event — such as a stroke or cardiac arrhythmia — occurred before the current swept Korwin toward the dock. If so, the story becomes even more complex. But whatever the final conclusion, the death of an athlete who once represented the U.S. team is a reminder that physical fitness is not a charm. Open water does not appear on a spreadsheet. It has its own rules, and even the strongest swimmer is merely a visitor.
