AIS ship type 89: Tanker, no additional information
Ship type 89 is the tankers family, units digit 9: no additional information. What it means, what it does not, and how many vessels we can hear sending it right now.
What code 89 means
Liquid bulk carriers: crude oil, refined product, chemical and gas tankers all share the 8x family. The units digit, where it is used, is the operator’s declaration about hazardous cargo, not the tanker’s design.
A units digit of 9 means "no additional information": the operator has set the family and explicitly declined to say anything about the cargo. Read it the same as the plain family code.
Reading the two digits
- Tens digit 8 → the tankers family, codes 80–89.
- Units digit 9 → no additional information.
- Therefore: Tanker, no additional information.

What the code is not
The ship-and-cargo type is typed into the transponder by whoever installs or operates it. No authority checks it against the ship’s certificates, and it is broadcast in the static report every six minutes whether or not it is right. It describes what the operator says the vessel is, not what it is doing — that is the job of the navigational status.
