Is it true that a 200 Ton Master can be used as a 500 Ton mate? Or is this someone pulling my chain?

No. It can’t. I can’t post a link to something that doesn’t exist, but look at [46 CFR 15.900 _et seq_.](https://www.ecfr.gov/cgi-bin/text-idx?SID=3200a1f752e387a66e4189fdaceec91d&mc=true&node=sp46.1.15.i&rgn=div6) and note that there’s nothing like it there.

This is strictly conjecture, but this twisted notion could have come from someone formerly having a 200 grt master (500 ITC) license. Who knows.

If you had a 200 GRT masters back in the day with STCW, you were granted 500 GT (ITC). The STCW was BST and II/3. That’s master 500GT OICNW. Now that requires the schools. As for your direct question, I don’t believe so.
