I have a question regarding upgrading from a 1600 master to thirdmate. Is it possible to use ITC time from a ATB to upgrade to thirdmate. I have over 10 years sailing a master on ATB’s. I know the cfr’s state that sailing 1 year as master on vessels over 200 grt qualify you to sit for thirdmate unlimited. The tug is 199 grt and the barge is 19073 grt. I know there is a navic out for using ITC time and the itc tonnage is 1077 for the tug. Is it possible to use the ITC tonnage to qualify for vessels over 200 tons?

Any input would be great.
