Percentageshiptypes

World wide frequency of ship types

I collected data from ~60000 Class A and 20000 Class B ships via AISHUB.

Message 5 and 24 include a ship type identification as described here (Table 11).

Tall Ship in front of Bute
Rarely seen Tall Ship in front of Bute

Most Class A ships are Cargo ships and most Class B ships are Pleasure crafts. No surprise here.
