Port Flow data briefs: the numbers behind the maritime news
Each brief crosses a real Port Flow signal with the story you're already reading — port congestion, chokepoint transits, AIS gaps, ETA accuracy. Observed, dated, sourced.
The news
The maritime headlines tell you something happened. They rarely tell you what the data underneath is doing — how many vessels are actually waiting, how many transits a strait saw this week, how far off the declared ETAs really are.
That's the gap these briefs fill. Port Flow already computes those signals live across 51 ports and 12 chokepoints. Each brief takes one of them, ties it to the news, and states the number — nothing inflated, nothing inferred.

What it implies
If you trade, charter, insure or screen tankers, the point is simple: you can check the number yourself, on a live desk, in one click — no signup.
The line
We're publishing data briefs — the real numbers behind maritime headlines: port congestion, chokepoint transits, AIS gaps, ETA accuracy. Observed, dated, sourced. portflow.uk/news
Coverage is public AIS; where it's thin (parts of the Med and the Gulf), we say so rather than overstate. We describe what the data shows, not why.
