What you'll do:

You and your group will board a private pontoon on Harsen's Island and spend two hours cruising Lake St. Clair's calm channels, with the freedom to drop anchor, swim, paddle, or simply drift with music playing and drinks in hand.

• Boat options: Choose a 23-foot tritoon for up to 10 guests or a 16-foot pontoon for up to 7, both fully equipped for a self-guided cruise on Lake St. Clair.

• Add kayaks or paddleboards: Rent paddle gear to go alongside your pontoon rental, so the group can split up, explore, and reconvene at anchor.

• Marina store stocked for you: Pick up ice, beer, wine, seltzers, snacks, or bait and tackle from the on-site shop before you push off from the dock.

• Made-to-order food: Place a food order at the marina before departure and fuel up properly rather than relying on chips and a cooler.

• Flexible hours: Rentals run from 8 AM to 7 PM, so you can catch the morning calm, a midday swim, or that late-afternoon golden-hour light.

Book this pontoon rental for your group if you want a day that actually feels like a getaway, not just an activity. The island setting and calm water do most of the work.

Why you'll love it for your bachelorette or birthday group:

• Private floating party: Your pontoon is yours alone, so there is no sharing the dock, the playlist, or the vibe with strangers.

• True island escape: Harsen's Island sits off the Detroit-area shoreline and genuinely feels removed from the city, even though it is an easy drive and ferry ride away.

• Cold drinks, no planning stress: The marina stocks beer, seltzers, wine, and snacks on-site, so your group does not need to haul a full cooler from home.

• Bachelorette-ready setup: This is one of the most-booked party boat rentals in the Detroit area for bachelorette groups specifically, and it earns that reputation.

• Kayak add-on for the adventurous half: Not everyone wants to lounge the whole time, and the paddleboard and kayak rental option gives the active crew something to do while others relax on deck.
