You might want to rethink scraping marinetraffic before you get a call from their lawyers?

Fair enough, I'm actually not scraping it on any automated cycle currently, I just manually copied the JSON from their site to get some ships on the map.

There's a few live ship tracking APIs I considered but they are expensive or their free offering just straight up didn't work. I sent a few an email if they would consider sponsoring the project, no replies yet.

    - AISStream.io — https://aisstream.io — Down/not working
    - DataDocked — https://datadocked.com — Ran out of credits on a single failed request
    - VesselFinder — https://www.vesselfinder.com/realtime-ais-data — Enterprise contact form, asked if they wanted to sponsor in exchange for a link
    - MarineTraffic — https://www.marinetraffic.com, their API is like an enterprise contact form, same as above, waiting for response.
