We strongly recommend planning to arrive at least 20 minutes early for your Cycleboat ride so you can board and get situated. For public tours, the boat will leave on time (without you) because we have a daily schedule to keep and it is not fair to the other passengers to shorten the cruise.
If you have booked a private charter, we will wait to leave but it will shorten your time on the water because we have a daily schedule to keep.
For North End, Seaport, or East Boston departures, the boat may arrive closer to 10 minutes before the departure time due to the need to shuttle from another location.
