Spencer Korwin: A 13:27 swimmer found dead under a dock – lessons from the 'good swimmer paradox'

In 2026, Spencer Korwin swam 13 minutes 27 seconds at the age-group triathlon world championships in Auckland. That number once proved he was comfortable in water. On a family vacation in Long Island, the same 38-year-old man went for a morning swim and never returned. His body was found under the dock of the Pridwin Hotel. His wife reported him missing after several hours. The weather was unremarkable. A local captain said the current is strong from the narrow passage when the tide flows. This is not just a tragic news story; it is a case study in the "good swimmer paradox." Korwin's 13:27 split suggests real swimming competence. Assuming a 750-meter sprint course, his pace was about 1:47 per 100 meters. Yet in open water, pool speed does not equal safety. Fast swimming matters only as long as a swimmer can choose his direction. Tidal flow through a narrow channel does not respect race splits; it can exhaust a strong body within minutes. Three risk factors created the tragedy: strong current in a narrow passage, solo swimming, and a long delay before anyone noticed he was missing. Pool swimmers often underestimate how quickly a tidal current can carry them away. They also overestimate their ability to fight it. A fit athlete can sprint for a few minutes, but the tide does not get tired. The fundraising page for Korwin's family had raised more than $361,000 by the time of the analysis, against a goal of $500,000. It shows how much people loved him. It cannot replace the missed afternoon swim or a missing check-in time. In my years of watching swimming and triathlon, I have learned that numbers only tell part of the story. The numbers connect only when we add environment, timing, and behavior. A team does not collapse overnight; it collapses when its indicators stop connecting. A safety system works the same way. Even a very good swimmer can become a drowning victim when he swims alone, without a float, without knowing the tide table, and without anyone watching the clock. The police investigation may reveal more about the medical cause of death. But the behavioral lesson is already clear: the safest swimmer is not the fastest one. The safest swimmer is the one who treats open water as an unpredictable environment and never assumes that once you can swim, you can always swim back.
