Private Group Events at Island Water Sports
Birthday parties, sports team outings, corporate events, and weddings on the Stone Harbor back bays.
Most Popular: Private Park Nights
Private Park Nights is our most popular group event for a reason. It’s the right fit for multi-family vacations, kids’ birthday parties (ages 6+), sports team end-of-season parties, and employee outings.
It’s also the smartest pick for bachelorette trips and bachelor parties — and most groups don’t realize it. The default move is to book a boat, but Private Park Nights gives you something a cruise can’t: the entire park, the deck, the inflatables, and the run of the place from 6 to 8 PM with water access until 7:30. BYOB, bring in catering, and the night runs on your timeline, not a captain’s. It’s a different kind of event — and the groups who book it have more fun than they expected.

Which Experience Fits Your Group?
Private Park Nights
Our most popular group event. It’s the right fit for multi-family vacations, kids’ birthday parties (ages 6+), sports team end-of-season parties, and employee outings of up to 50 people. It’s also the underrated pick for bachelor and bachelorette trips — the whole park to yourselves, BYOB, catering on your terms, and the night runs on your timeline.
The Stone Harbor Charter
The right fit for groups of up to 22 who want to be out on the water — wedding parties, milestone birthdays, corporate cruises, or a group that wants to combine cocktails with a sunset on the back bays.
Group Tubing
For the group that wants water sports as the main event. Up to 22 guests, 1.5 hours behind the boat, and everyone gets a turn. Sports teams, summer camps, and bachelor parties love this one.
The Complete Water Experience
The all-day group package — boat charter, water sports session, and Aqua Park access combined. The flagship build for groups that want everything. Up to 6 guests on the small group package, or 7 to 22 on the large group package — depending on boat capacity.
Frequently Asked Questions
How far in advance should I book?
Most groups book a few weeks out, and we’ll work with shorter timelines when we can. Peak weekends in July and August fill up faster, so the earlier you reach out, the better your date options. Last-minute inquiries are always welcome — just call or email.
What’s the maximum group size?
Private Park Nights: up to 50 participants (spectators don’t count and are free). Stone Harbor Charter: up to 22 guests. Group Tubing: up to 22 guests. The Complete Water Experience: up to 6 guests on the small group package, or 7 to 22 on the large group package — depending on boat capacity.
Can we bring our own food and drinks?
Yes. Private Park Nights and all boat charters are BYOB, and coolers are welcome.
Do you handle catering?
We recommend using our in-house option, The Watering Hull, for an easy, dialed-in catering experience. Any local restaurant will also deliver to the dock or the park, or you can bring your own food. Whatever works best for your group.
What if it rains?
We monitor weather closely and make the call together. If conditions aren’t safe — heavy rain, thunderstorms, dangerous wind — we’ll reschedule to another date that works for your group. We don’t run private events in bad weather.
Is there a deposit?
A $1 booking fee secures your date for all experiences. There’s no separate deposit.
What’s the cancellation policy?
Boat charters, Group Tubing, and The Complete Water Experience: free cancellation up to 24 hours before your scheduled time. Within 24 hours, the full amount is charged. Private Park Nights: free cancellation up to 7 days before your event. Within 7 days, the full $1,200 minimum is charged. If we cancel for unsafe weather conditions, you’re never charged.
Do you do corporate events and team building?
Yes. We host employee outings, sales team trips, and corporate retreats regularly. Private Park Nights works well for groups that want a contained experience with a clear start and end. Stone Harbor Charter buyouts work well for groups that want to be on the water with cocktails and conversation.
Can kids attend Private Park Nights?
Yes — Aqua Park is open to anyone ages 6 and up, and Private Park Nights is one of our most popular kids’ birthday party experiences. The deck and viewing area give parents and chaperones a clear sightline on the water.
Where are you located, and where do we park?
9701 3rd Avenue, Stone Harbor, NJ. Street parking out front is metered and paid. Free street parking is available on 99th Street and above. We’re on the back bay side of Seven Mile Island, about 10 minutes from the Garden State Parkway and 15 minutes from Avalon.
How do we book?
Three ways: book each experience directly through its activity page on this site, email Tom at Tom@islandwatersportsnj.com to talk through a custom group, or call (609) 368-6114. Whichever works for you.
Have something else in mind? Corporate retreats, bachelor parties, surprise proposals, multi-day group bookings — if it’s on the water, we can build it. Email Tom directly and let’s talk.
