Book the same two hours on Rum Barge Adventures twice and you could end up with two completely different days. One group keeps it low-key — quiet water, good light, everyone just glad to be off their phones. The next books the identical boat and turns it into a full-blown floating party, complete with a giant inflatable float trailing behind and a cooler that never runs dry. Same crew, same dock behind Cowfish, same stretch of Shinnecock Bay. The difference is entirely up to whoever's planning it.

‍

That flexibility is worth spelling out, because most people booking a Hamptons boat charter default to picturing one version of it — either a scenic tour or a floating rager — without realizing the same operator covers both ends and everything in between. A relaxed daytime cruise, a social one built around music and drinks, or a fully private party atmosphere with food and floats: all three are variations on the same private charter, not separate products, which means the group gets to decide the mood rather than pick from a fixed menu.

‍

What actually comes with the boat

‍

The baseline covers more than most people assume before they ask. Every charter includes an experienced local crew, comfortable seating, shade, an onboard restroom, complimentary water, and fresh fruit — the kind of small details that matter more on a two-hour bay cruise than they sound like they would on paper, especially with a group that skews toward "please don't make me stand the whole time" rather than "we want to be roughing it." From there, the group builds out the rest: a Yeti cooler add-on for anyone who wants their own drinks kept cold without babysitting a cheap cooler, a giant float for the group that wants a swim stop built into the afternoon, and catering pulled directly from two of Hampton Bays' own waterfront spots, Cowfish and RUMBA, so the food doesn't have to be an afterthought packed in a cooler bag.

Building the day around what your group actually wants

‍

The FAQ on the booking page puts it almost exactly right: these charters exist for anyone trying to avoid the fate of a generic group dinner. That's a real planning problem for bachelorette weekends and milestone birthdays specifically — dinner reservations are easy to book and forgettable to attend, while a two-hour private boat block forces an actual activity into the middle of the day instead of another round of drinks at a table. Because the format doesn't lock a group into one specific vibe, it works as well for a bridal party that wants string-of-pearls photos in good light as it does for a bachelor party that wants a Yeti of beer and open water.

‍

Private Celebration Charters run 2 to 3 hours, with pricing starting at $700 for up to six passengers and $85 for each additional guest — a structure that makes it straightforward to price out exactly what a bigger group will cost before locking anything in, rather than guessing at a per-person rate that might not scale the way you expect.

‍

What to actually pack

‍

Sunscreen, sunglasses, a hat, a towel, and a light cover-up cover the basics; bathing suits are optional depending on which version of the day the group books, since not every charter ends in the water. Glass containers aren't permitted onboard, which is worth passing along to the group chat before someone shows up with a case of bottled rosé. Beyond that, the day is mostly about deciding in advance which version of the boat you're booking — because unlike a lot of Hamptons charters that only run one kind of trip, this is the rare one where the crew, the dock, and the route stay exactly the same no matter which mood the group picks.
