ATB's qualify as unlimited tonnage?

[QUOTE=tugsailor;163785]I’d still like to know, if a tugboat guy has:

  1. Master 1600 and master of towing

  2. 1000 days sailing as master on tugs over 100 GRT (mostly 199)

  3. Over 360 days sailing as master of documented tug and barge combination tonnage over 5000 GRT, which is credited 2/1, totaling over 180 days toward Third Mate

  4. But no time on conventional vessels over 1600

What if any tonnage limitation should he expect to receive on Third Mate “Unlimited” ? ? ?[/QUOTE]

I would expect you could argue convincingly for 5,000 GRT based on this line from the CFR: “The endorsement will be limited to the maximum tonnage on which at least 25 percent of the required experience was obtained”

Your 5,000 GRT tug/barge combo was at least 25% of your sea time…
