Differentiator
Open tonnage & laden/ballastBulkers and tankers
Which bulkers and tankers just discharged, are now in ballast or about to sail, and where they say they are going next.

Everything you get from the data
Four signals per port, the vessel and port-call records behind them, and the channels that deliver them, across the North Sea, Baltic, English Channel and Irish Sea.
The signals
Four signals per port, and more
The questions people around a port ask every day, answered directly, with the ports and ships behind them a click away.
Signal
Congestion & waiting indexAt anchor
Ships waiting at anchorage and for how long, by type and laden state, against the port's own baseline.
Signal
Turnaround timeArrival to departure
Arrival to departure per port, and per terminal where the geography allows. A slowdown shows here first.
Signal
Arrival wave forecastNext 7 days
How many ships are heading in over the next 1–7 days, laden and ballast, worked out from position and speed rather than the reported ETA.
Every plan
Port profiles
Who calls at each port: the classes, sizes and flags, where ships head next and how laden they are.
Pro and up
Vessel search and watchlist
Search every ship we track, and follow the ones you care about with a daily email digest.
Every plan
A confidence score on every figure
Each figure says how much it rests on, so you know when to act on it and when to check. Where we cannot tell, we say so rather than guess.
#Auditable#No guesswork
What a signal looks like: the open-tonnage list
One row per ship that has just discharged or is about to, with its state, next reported destination and how much we trust the reading.
| Vessel | Event | Port | State | Next destination | Confidence |
|---|---|---|---|---|---|
| Bulk carrier · Capesize | Discharged | Rotterdam | Ballast | Reported: Brazil | High |
| Tanker · Aframax | Discharged | Gdansk | Ballast | Not yet reported | Medium |
| Bulk carrier · Panamax | Discharging | Hamburg | Part-laden | Not yet reported | Low |

Coverage
One region, covered properly
Four connected seas that trade with each other all day, with dense coastal AIS reception along most of their shores.
North Sea
The Amsterdam–Rotterdam–Antwerp range, the German Bight and the Elbe, and Britain's east coast.
Baltic Sea
Copenhagen and the Danish straits, Kiel and Rostock, Gdansk and Gdynia, Klaipeda and Tallinn: grain, fertiliser, forest and oil products.
English Channel
Le Havre, Dunkirk, Southampton and the Dover Strait, where Atlantic traffic funnels into the North Sea.
Irish Sea
Liverpool and Dublin: bulk, liquid and ro-ro trade between Britain and Ireland.
The free plan covers Rotterdam; paid plans cover every port we publish in the area. A port is added once its measured reception holds up.
Method
Intelligence you can audit
AIS is self-reported and patchy. We build around that instead of hiding it, so you know when to act on a figure and when to check.
A state, not a guess at tonnes
A capesize at 18 m against 8 m is unambiguous even when a tonnage estimate would be far off. We classify laden, part-laden or ballast, and label any tonnage figure as a supporting estimate.
Confidence with every figure
AIS draught is typed in by crews and is often late or wrong. Each port call carries a confidence score, and each daily figure says what share of calls had a usable reading.
Coverage measured, not assumed
Terrestrial AIS is coastal and uneven. We publish a port once we have measured dense reception there, and say so where we have not.
