It isn't international registers, so we exclude.

That's way, Surabaya is waiting you back mr Pieter.. :)

Pieter, Actually k.m. is an abbreviation for "kapal motor" and this is Indonesian for Motor Vessel (MV), and is optional to be included.

There is k.m. in front of the name (kapal motor?). I took a shot of the ship in 2014, also in Madura Strait, and also with k.m. before the name. To what extent is k.m. part of the official name?
