Docking at Quincy Float between neap cycles

Quincy Float lies tucked between the old customs warehouse and the railway trestle, just upstream of where Trellis Basin opens to the main channel. The structure itself dates from the early nineteen-hundreds—heavy timber cribbing filled with ballast stone—and it rides eight feet lower than the newer municipal docks downriver. That elevation matters during neap tides, when the range shrinks and the approach corridor closes faster than most transient boaters anticipate.

Reading the cycle

Neap tides arrive twice monthly, roughly a week after each new and full moon. During those periods the flood never quite reaches the pilings that mark safe depth at the float's outer edge, and the ebb leaves barely three feet over the gravel bar that runs parallel to the trestle. The harbor master's office posts a single-sheet schedule each month—pick one up at the fuel dock or check the board outside the chandlery on Decatur Street. The window opens two hours before local high water and closes an hour and twenty minutes after. Miss it and you're waiting six hours for the next attempt.

I've watched skippers try to force the approach an hour early, convinced the gauge at Prescott Dock tells the whole story. It doesn't. Quincy sits a quarter-mile upstream and the bar shoals unevenly. The safe line runs thirty yards off the trestle's shadow, marked by a pair of orange buoys that the harbormaster replaces each April. Hold that line until the float's cleat comes level with your bow, then turn hard to port.

Securing and departure

The float takes four boats comfortably, six if everyone rafts tight and nobody's carrying a dinghy on davits. Cleats are spaced for thirty-footers; anything larger and you're doubling lines to share hardware. Spring lines matter here because the current runs three knots on the ebb, even during neaps, and the float's downstream edge sits only eight feet from the trestle's stone footer.

Power is available—two pedestals, fifteen-amp service—but water comes from a single spigot near the landward stairs and the valve sticks. Bring a wrench. The stairs themselves climb eighteen feet to the warehouse parking area, where you'll find the footpath that connects to the basin walk described in our Narrows guide.

Departure requires the same attention to the window. If you're still tied up ninety minutes past high water, you're staying until the next flood. The gravel bar builds quickly on the ebb, and I've seen keels touch bottom in less time than it takes to stow fenders and coil dock lines. The harbormaster doesn't tow off the bar during neaps—policy since two-thousand-six, after a keel repair dispute—so you wait for water or you kedge yourself into deeper channel, and neither option improves anyone's afternoon.

Check the monthly neap schedule before you plan a stop at Quincy. The float offers quiet access to the upper basin and a short walk to three decent restaurants, but only if you time the approach and work inside the window the tide provides.
