01
Three things a sailor needs
The tide, the window, the gear. Everything else is decoration.
/ 01
Read the tide
Two highs, two lows, and the stream in between. Drift pulls the station nearest your slip and makes it legible at a glance.
/ 02
Pick the window
Coastal hops and overnights, planned against real forecasts and the current — so you ride the flood instead of fighting it.
/ 03
Run the gear
Anchors, foul weather, safety, and navigation — checked lists for the kit you hope never to need.
02
Everything but the weather guesswork
Know more, guess less.
Tide tables, readable
Times and heights for your station, in a table a human can scan in the cockpit.
Currents that run live
Set and drift for the channel, so slack water stops being a rumour.
Weather windows
Fronts, pressure, and sea state — laid out so a good window looks boring.
Gear checklists
Scope, flares, jacklines. The kit, logged and dated, ready when it's dark.
Coastal passages
Day hops and overnights, planned from the crux back to the dock.
A real logbook
Hours, fixes, and the small notes that save big bills later.
03
The coast, up close
Shot where the water actually moves.

The tide, one day at a time
Drag the slider — watch the water rise and fall.

From the desk of Elias Marner
Most apps tell you the time. Drift tells you when the water will let you go.
I learned to sail on a bar that only opens four hours a day. Miss it and you wait — tied to the quay, watching the channel run, with nothing to do but re-read the tide table and wish it made more sense.
So I built drift the way I wanted that table to read: the four numbers that matter, the stream between them, and the window where the boat can actually move. No weather theatre, no ten-tab forecast. Just the tide, the window, and the gear.
The invitation is the same one I give every new crew: leave at slack water, ride the flood, and be tied up by lunch. That's the whole product.

Skippers, on the record
People who made the bar.
★★★★★
"I've run the same inlet for years. Drift is the first thing that shows me the window instead of just the numbers."
Wren H.Cruiser
★★★★★
"The rule of twelfths page alone is worth it. I check it every time I anchor for lunch."
Marcus D.Daysailor
★★★★★
"It reads like a logbook a friend keeps. The tide, the window, the kit — nothing extra."

Questions, answered.
Where does the tide data come from?+
We pull from public tide stations and harmonic predictions, then re-render them as readable tables and curves. Every height is shown above chart datum.
Does drift work offshore?+
The tide tables need a station nearby, so drift shines near-shore and in coastal waters. Offshore, the weather windows and logbook keep working.
Is it just tide tables?+
No. Tides, currents, weather windows, passage planning, gear checklists, and a real logbook — the whole near-shore toolkit.
Is it free?+
Yes — the core tide tables and logbook are free during beta and stay free after launch.
Do I need to be a sailor to use it?+
No. If you paddle, fish, or just walk the shore, the tide tables and currents are the same. The sailing depth is there when you want it.
Can I log engine hours and fixes?+
Yes — the logbook records hours, fuel, fixes, and the small notes that keep a boat honest for its next owner.
The water is already moving.
