I have a 150 master/ 200 ton Mate INLAND license. Looking at possible upgrades, there are some interesting opportunities for someone holding a master NMT 200 GRT:
90 days on deck while holding master NMT 200 inland gets you 200 GRT NC mate.
360 days as master on vessels over 50 GRT while holding a master NMT 200 GRT (720 days total) gets you 1600 GRT mate inland.
1080 days master of vessels 200 GRT or less (plus 30 and TOAR) gets you mate of towing.
My question is does a 150 ton master count as master NMT 200 GRT? Does a 100 ton master? My first two issues were 100 ton master/ 200 ton mate inland and only have a little time while holding the 150 ton master.
