The Experience

Our Cruises are scheduled to meet at Pier 6 in the Navy Yard in Charlestown or India Wharf downtown next to the Boston Aquarium. These docks open directly into the incredible Boston Harbor. You will board our vessel, store your beverages and snacks, receive a quick introduction and review our safety protocols. Then it’s time to pedal out onto open water or relax and enjoy the amazing Boston Harbor!

From the Cycleboat, you’ll see Boston like never before! Take in the amazing views and soak up their history. Landmarks like the East Boston Tall Ship, Nantucket Lightship, Logan Airport, South Boston Seaport, Boston Tea Party Ship, the Downtown and Northend Waterfront, Boston CoastGuard Station, TD Garden, Bunker Hill Monument and the Historic Charlestown Navy Yard with the USS Constitution and WWII destroyer Cassin Young.

Just choose a seat at the table and pedal as much or as little as you like or just relax in the lounge area. Your cruise will take you to the shoreline of East Boston, South Boston Seaport, Fort Point Channel, Downtown and Northend Waterfront, Charles River Basin and the Charlestown Navy Yard. After 1.5 hours on the water, we’ll head back to Pier 6, exit the vessel and say our goodbyes. You’ll leave with a smile on your face after experiencing one of the BEST Boston Harbor Day Cruises!

Boarding Locations and Enroute Attractions

Some of Our Most Frequently Asked Questions


No, don’t worry! Most people take turns and have fun pedaling or just cruising. The captain can raise or lower the paddle wheel to reduce the resistance, making the pedaling easier (just like lowering the gear on a bicycle). We can also supplement your pedal power with the outboard motor, so no one has to pedal!

Yes! Riders who are of age are welcome to bring beer, wine or pre-mixed cocktails (no hard alcohol) while they enjoy their Cycleboat ride! Of course non-alcoholic beverages are okay too!

Public bathrooms are available at our boarding locations. There are also bathroom aboard our boats (Rosie the Riveter, Minuteman and Sweet Caroline) for emergencies.

  • It’s unlikely you’ll get wet, but dress for the weather conditions and for comfort, it can be a little windier or cooler on the harbor, so we do recommend bringing an extra layer especially for evening tours.
  • Sunglasses and hats are great but you will be seated under a large canopy shielding direct sun and rain.
  • No need to bring a cooler as we have ice chests with ice in the center bar between the pedal stations for passenger use.
  • Also, snacks are great or anything you can eat with one hand (i.e. sandwich)
