Mining AIS Vessel Data Turns Up 50,000 Boat Names Full of Puns and Pop Culture

A data journalist pulled roughly 50,000 named vessels from NOAA’s Marine Cadastre broadcast-point dataset, which captures Automatic Identification System (AIS) transmissions from terrestrial stations along US waterways. AIS is mandatory for most commercial ships 65 feet and longer, but many recreational boaters broadcast voluntarily. Of about 150,000 unique boats sampled, only around a third transmitted a name, and pleasure craft dominated the results at 43 percent, followed by cargo ships, fishing boats, tugs, and ferries.

The names double as a window into who owns boats and what they do for a living. Given annual ownership costs of $15,000 to $40,000 and a demographic that skews heavily white and affluent, the dataset is thick with finance puns (LIQUID ASSETS, 401(PLAY)), legal wordplay (MOTION GRANTED, PRO BONO), and medical in-jokes (ENDORFIN, SPIKE AND WAVE). The rest ranges from crude nautical puns to dense references across literature, film, and TV—Tolkien, Star Wars, Star Trek, and an unusually large contingent of Seinfeld deep cuts like FESTIVUS and NO SOUP FOR YOU.

Beyond the novelty, the piece is a small case study in extracting personality from bureaucratic open data, joining the author’s earlier trawls through waypoint names, rejected vanity plates, and pet licenses. The analysis was built in a Python Jupyter notebook, with Claude Code used to help categorize names and assemble an interactive browser, and the underlying data is published for others to explore. It’s also a quiet reminder that AIS broadcasts precise location and identity in the clear—useful for mapmakers and anyone else listening.
