What you'll do:

Board a 62-foot private catamaran in Sag Harbor and spend three hours on the open water with your group, swimming, lounging, toasting, and watching the Hamptons coastline drift by from the best seat in the house.

• Swim off the back deck – Drop into the water when conditions allow, using the boat's swim platform and onboard floats for an easy, relaxed dip.

• Claim your spot on deck – Stretch out on the bean bag seating or find a shaded corner with a drink in hand while the captain handles the rest.

• Set the soundtrack – Connect your playlist to the Bluetooth sound system and let the music set the pace for the whole charter.

• Toast the sunset – Crack open your own champagne, wine, or drinks of choice, BYOB is fully welcome, and ice, cups, and basic cutlery are provided.

• Take in the Hamptons from the water – See Sag Harbor, Shelter Island, and the open sound from a vantage point most summer visitors never get.

There are no crowds, no itinerary to stick to, and no rushing. By the time you get back to the dock, it'll feel like the summer day everyone needed.

Why we love it for your group:

• Private charter, your group only – No strangers, no shared schedule, the entire 62-foot boat is yours for the full three hours.

• Captain and crew included – Experienced professionals handle navigation and hosting, so your group can focus entirely on enjoying the day.

• Room to spread out – Indoor and outdoor lounge areas, shaded seating, bean bag deck space, and two onboard bathrooms make the boat feel genuinely comfortable for larger groups.

• BYOB-friendly setup – Bring exactly what your group likes. Ice, cups, and water are provided; you stock the rest.

• Sunset timing options – Evening charters are especially popular in summer when the light hits the water perfectly, and temperatures drop just enough.
