If you've spent a summer evening anywhere near the water on Centre Island, you've heard it: a single horn blast around six, coming off the Sound side, followed twenty minutes later by another. If you've never sailed a day in your life, you've probably assumed it was just boats. It isn't just boats. It's a race, and it has been the same race, more or less, since before your house was built.
The horn belongs to Seawanhaka Corinthian Yacht Club, the private club at the end of Yacht Club Road that most non-members know mainly as a handsome building behind a hedge. What's easy to miss, living alongside it, is that the club's calendar is the actual metronome for a lot of what happens on this peninsula between Memorial Day and Labor Day. The beach fills differently on race nights. The junior program empties out the same handful of families every August. And the boat everyone is racing has changed more times than most residents realize, which turns out to be the whole reason the club is still here at all.
The Club That Almost Left For Manhattan
Seawanhaka started in 1871, not on Centre Island but aboard a 41-foot sloop called Glance, where the founding members held their meetings because a proper clubhouse didn't yet exist. Within a few years, as members traded up to bigger boats, the center of gravity drifted away from Oyster Bay toward New York Harbor, where the real yachting action was. The drift went far enough that the members who stayed behind eventually broke off to start their own Oyster Bay Yacht Club, feeling left out of a club that had, in practice, moved on without them. Seawanhaka spent the 1880s leasing space on Staten Island, where it picked up the word "Corinthian" in its name, then leased a clubhouse in Manhattan.
It wasn't until 1891 that the club decided to stop leasing and commit to a permanent home. It came back to Centre Island, merged with the Oyster Bay Yacht Club it had effectively orphaned, and opened the clubhouse that still stands today, all barely two decades after the whole thing started on a sailboat. That clubhouse has been listed on the National Register of Historic Places since January 8, 1974, which is a fact most residents know. What's less commonly told is that the club almost didn't come back at all, and the version of Centre Island's waterfront we take for granted today exists because a group of restless yachtsmen changed their minds.
Every Generation, a Different Boat
Here's the part that explains why the Wednesday races still matter instead of feeling like a historical reenactment. Since 1892, the club has never gone without an active one-design class, meaning a fleet of boats built to the same specifications so racing comes down to sailing skill, not who spent more on the hull. But the specific boat has changed again and again, and each swap tracked a real shift in what small-boat racing looked like nationally.
| Era | What the club raced |
|---|---|
| 1892 onward | Early one-design classes: 21-footers, Fifteens, Knockabouts, Raceabouts, and several locally named fleets |
| 1950 | The Raven, a 24-foot centerboard planing sloop, introduced by Seawanhaka members and adopted as a national one-design class |
| Mid-to-late 20th century | Shields, then Solings, then Etchells, then J/24s, as each class rose and fell in national popularity |
| Today | Sonars, raced weekly, with biweekly team racing in the same fleet |
That table isn't trivia. It's the reason the club still fields competitive teams instead of just maintaining a museum piece of a building. Members who came up through the Raven era in the 1950s watched the fleet change again in their own lifetimes, and the junior sailors training in Sonars this month will likely watch it change again in theirs. The club also still competes for the Seawanhaka Cup, the trophy it created for match racing between clubs, which is recognized as the oldest active yachting trophy that originated in the United States. A century and a half of continuously updating the equipment is what keeps that history from turning into a plaque on a wall.
What Still Floats Every Wednesday
The club's on-the-water season runs roughly April through October, with the clubhouse itself open year-round and the boatyard and ship's store running on regular hours straight through winter. But the in-season stretch, from Memorial Day through Labor Day, is when the calendar is busiest: weekly one-design Sonar racing, biweekly team racing, a rotation of PHRF and series regattas for handicapped fleets, and a Junior Sailing Program that runs clinics for members and non-members alike, with scholarships available for families who need them. The junior program has its own clubhouse separate from the main building, which is where a lot of the island's kids spend their August afternoons whether or not their parents ever set foot on a race committee boat.
Labor Day, September 7 this year, marks the formal turn from in-season to off-season operations. That doesn't mean the club goes quiet. Frostbite racing in small dinghies has historically continued through the winter months for members who don't want to put the season away just because the calendar says so. But it does mean the Wednesday gun you've been hearing all summer is on its last few rounds before the fleet thins out.
The Beach That Doesn't Pick a Side
A five-minute drive from the clubhouse, at the end of Bayville-Centre Island Road, sits the one public spot on this stretch of shoreline that isn't private at all: Centre Island Beach, a Town of Oyster Bay park. What makes it genuinely unusual, not just locally described that way, is that it lets you swim in both Oyster Bay Harbor and Long Island Sound from the same parking lot, a dual-water setup you don't get at most beaches along this coast. It's also open to both Town of Oyster Bay residents and non-residents, unlike some neighboring town beaches that restrict access to residents only.
The Town of Oyster Bay's parks department has this location running with daily lifeguard coverage through September 7, matching Labor Day, which means the final week of August is the last stretch of full-season hours before the beach shifts to its quieter fall footing. The park also does something most town beaches don't: it rents skull racks, storage for rowing shells, specifically at Centre Island Beach and nowhere else on the town's list, alongside the more familiar kayak racks. It's a small detail, but it tells you something about who actually uses this beach. It isn't just families with towels. It's rowers and paddlers who treat this particular stretch of water as a launch point, not just a swimming hole.
The Storm Habit Nobody Talks About
If you've lived here more than a summer or two, you already know to check before you swim after a heavy rain. Nassau County's Department of Health issues bathing advisories when stormwater runoff pushes bacteria levels above the state standard, and Centre Island Sound in Bayville has shown up on that list multiple times this summer, including stretches in late July and early August, each one lifting within a day or two once fresh water samples came back clean. It's not a Centre Island problem specifically. The same advisories hit beaches up and down the Gold Coast, from Lattingtown to Laurel Hollow, whenever a storm rolls through. But the local habit of calling the recorded hotline at (516) 227-9700 before packing the cooler is one of those small pieces of knowledge that separates someone who's actually lived here from someone reading a beach guide.
The Last Lap Before Labor Day
None of this is really about boats or bacteria counts. It's about what actually paces a summer on a 605-acre peninsula with just under 200 households and four miles of coastline. The tide comes and goes twice a day, but it doesn't tell you anything about the season. The Wednesday gun does. So does the sight of the junior sailors packing up their Sonars for the last time before school starts, and the beach lot at the end of the road finally thinning out after Labor Day weekend. The club that almost left for Manhattan in the 1880s, and the boat class that's changed six or seven times since, are the reason that rhythm still feels alive instead of ceremonial.
