A Club For All Seasons

The Mount Sinai Yacht Club is located in the desirable Town of Brookhaven on beautiful Mt. Sinai Harbor, just east of Port Jefferson. Composed of family and individual memberships, boaters and non-boaters, members and their guests are welcome to enjoy the wide range of year-round activities offered by MSYC.

The members of MSYC use good spirit and old-fashioned hard work to make the original vision a reality. Come in to the clubhouse and have a beverage with friends, enjoy a meal on the patio with sprawling views of Mt. Sinai harbor, or walk the docks to share some laughs with fellow members listening to stories of the “one that got away!”

And if that’s still not enough, take a short stroll across the street to Cedar Beach for fishing, swimming and sunsets over the picturesque Long Island Sound. The Mount Sinai Yacht Club is the #1 destination for summer fun!
