Sketchy Boats

Sketchy Boats is a site created by maritime researcher Christian Panton. It tracks ships with “murky paperwork, shady ownership, strange port calls, and a suspicious tendency to vanish from tracking systems”. Sketchiness scores are calculated by a number of red flags including switching flags or names, questionable insurance documents, spending time off the coasts of sanctioned countries and going dark from tracking systems. There is a globe you can spin to see a heat map of these ships. 

You can also bring up the list of ships and click for more information.

Here is a detail of the Ocean Embrace, one of the ships with a top sketchiness score, currently sailing under the flag of Sierra Leone.

There are also links below to other tracking sites such as VesselFinder and Global Fishing Watch, which has its own ship tracking visualizations.
