New 39-Foot Powerboat Grounds on Great Reef off Sheffield Island; Crew Rescued

A newly purchased 39-foot powerboat, valued at approximately $300,000, ran aground on a large rock formation off Sheffield Island in Norwalk, Connecticut, on Wednesday morning. The owner and a delivery captain were transporting the vessel northbound from Stuart, Florida, to Portsmouth, New Hampshire, when they struck what is known locally as Great Reef — an area notorious for hidden hazards and rapidly changing conditions.

Both the owner and the delivery captain were rescued by the Norwalk Police Department’s Marine Division and are reported to be safe. Sgt. Peter Lapak, head of the Marine Division, described the situation as among the most dangerous he has encountered in his career, citing the location on the reef and the harsh sea conditions. “In my whole career this was one of the worst ones, one of the most dangerous ones because of where we had to go, on top of the reef, and the sea conditions–the water was really cold,” he said. The tide was rising at the time of the grounding, and the boat sank shortly after the two men were taken to safety.

The vessel was on a long delivery voyage up the Intracoastal Waterway (ICW) and nearby coastal waters when the weather and sea state unexpectedly deteriorated. According to accounts from the scene, the crew encountered 5- to 7-foot seas in Long Island Sound. In an effort to reduce exposure to the heavy swells, they altered course toward Connecticut’s south shore. While attempting to shelter from the waves, the boat passed too close to Sheffield Island and ran directly onto a large pile of rocks.

Visibility and electronic navigation presented additional challenges. Wind and waves made it difficult to read the boat’s electronic GPS screens, and the rock formation was not recognized in time to avoid grounding. After the grounding, local authorities and Sea Tow were engaged to assist. Sea Tow is actively working on vessel recovery and salvage efforts, while authorities continue to secure the scene and assess environmental and navigational risks posed by the sunken boat.

Although the two crewmembers were experienced boaters, the incident highlights how quickly conditions can change on coastal waters and the risks of operating near shorelines and hidden reefs. Cold water, rising tides, and large swells can complicate navigation, hamper rescue operations, and increase the chances of structural damage to a vessel. The Norwalk Police Department’s Marine Division coordinated the rescue under challenging circumstances, emphasizing the importance of preparedness and quick response for vessels in distress.

This grounding serves as a reminder to boat owners and delivery crews of several important safety considerations: maintain up‑to‑date charts and electronic navigation aids, double-check local hazards when altering course near islands or shorelines, monitor weather and sea-state forecasts closely, and have contingency plans for seeking shelter or requesting assistance. Even experienced mariners can encounter situations where multiple factors — weather, sea state, limited visibility, and unfamiliar local hazards — converge and lead to an emergency.

Authorities are continuing follow-up work at the scene. Sea Tow’s salvage operation will determine whether the vessel can be recovered intact or if further action is required. Local officials will also review the incident to identify any navigational or safety lessons that could prevent similar groundings in this sensitive and often treacherous area of Long Island Sound.

The owner and delivery captain are recovering following the rescue. No further injuries have been reported. The incident remains a cautionary example of the hazards of coastal navigation, even for new vessels and seasoned operators.
