Port Call

A port call record captures one vessel arrival-departure cycle at a berth or anchorage, including timestamps and events.

Tracking platforms sell them as per-vessel histories, and UNCTAD aggregates them into national port-call performance indicators.

In this catalog it appears concretely: - MarineTraffic offers — "historical port calls and events for multiple past years". - UNCTADstat includes — "port calls performance". - VesselFinder sells — "per-vessel port call and event histories".

A label on a listing is not a deliverable. Teams that license on the strength of a product-name match routinely find the shipped files cover a narrower slice than they assumed, and backfilling history afterwards costs more than the license ever did.

The failure mode is concrete: a source can carry the Port Call label while differing from what you need on exactly the dimension that matters — historical port calls and events for multiple past years. Comparing two sources on that line usually settles the choice faster than any feature matrix.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and MarineTraffic offers lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open MarineTraffic offers and confirm its record — "historical port calls and events for multiple past years" — against the files you actually receive.
2. Open UNCTADstat includes and confirm its record — "port calls performance" — against the files you actually receive.
3. Open VesselFinder sells and confirm its record — "per-vessel port call and event histories" — against the files you actually receive.
4. Pin down update cadence in writing. Across this catalog, 22.6% of 1,744 datasets refresh daily and 64 still arrive only through a manual request form, so ask exactly how fresh each release is.
5. Check whether definitions are verified at all. Field definitions are verified for 1495 of 1,744 datasets (85.7%), and any source you license should meet that bar.
6. Price the delivery route before the license. In this catalog bulk download is the most common access method (725 datasets) ahead of official APIs (574), and 379 sources still require scraping — a maintenance cost that lands on you, not the vendor.
