The Bellamy Pier launch operates on quarter-tides
Understanding the quarter-tide system
Bellamy Pier sits at the narrow mouth where the basin empties into the main channel, and the launch service there has operated on quarter-tides since 1847. The captain marks each quarter by the waterline against the fourth piling—the one with the copper band—rather than consulting a clock or the printed schedule available at the harbor master's office.
This matters because the launch only makes the crossing to Drift Island when the water reaches specific marks. First quarter after high slack, third quarter on the ebb. Miss those windows and you'll wait roughly ninety minutes for the next departure, though the interval shifts daily as the tides themselves shift.
What the chalkboard actually tells you
The small chalkboard mounted beside the ticket box lists times, but those times represent estimates based on the previous month's tide tables. In practice, the launch leaves when the piling shows the correct waterline. I've watched visitors argue with the ticket seller about a 2:15 departure that didn't happen until 2:40 because the tide was running late that afternoon.
The ticket seller will not hold the boat if you arrive after the quarter-mark passes. The crossing takes eleven minutes in calm conditions, longer if the wind is running against the current, and the captain prefers to make the turn at Drift Island's stone landing before the water drops another six inches.
Planning your crossing
If you're coordinating with the outbound packet from Salter Pier, leave yourself a full two-hour cushion. The packet keeps to a printed schedule; the Bellamy launch does not. Travelers who try to thread both services on the same afternoon often end up walking the long way around the basin road instead.
The launch runs April through October. No service November to March, when ice can form in the narrow channel. No advance reservations—tickets are sold at the box ten minutes before the estimated departure, first-come basis. The boat holds fourteen passengers plus the captain.
The return schedule
The return launch from Drift Island's landing operates on the opposite quarters—second and fourth. That means if you cross on the first quarter outbound, you'll wait through two full quarter-cycles on the island before the return boat arrives. Most people use that time to walk the perimeter trail or sit at the Drift Island Ordinary, which serves coffee and sandwiches until four.
Bring a watch that shows the date. The tide tables posted at both landings are updated weekly, but they don't account for weather delays or the spring tides that can shift the quarter-marks by twenty minutes or more. The copper band on the fourth piling remains the final authority.
