I recently upgraded to 2M and already had a Master 1600/3000 Oceans and Master OSV (post 6000). My Original endorsement just said “Master OSV”, no tonnage limitation.
When I get my MMC my evaluator said the Large OSV endorsement will state “Master OSV 500GT/6000ITC”. When I asked my evaluator about it he said that he looked into it and the Large OSV endorsements that were previously issued without a tonnage limitation were issued erroneously.
Anybody heard a similar story/explanation?
