Tonnage issues..... Where can I get some answers?

[QUOTE=jdcavo;53913]Any gross tons, without any limitation, is good for any tonnage, GRT or ITC.[/QUOTE]

But as long as my ticket is endorsed with 3000 GRT only, I will NOT be allowed to ride on a vessel that has ITC tonnage only on the COI? Duel tonnage vessels are fair game as long as GRT tonnage listed is less than 3000?

Sorry if I am missing something here but need to get this straight.

Per 11.402 ©, (1) 6 months over 1600 GRT and unlimited is mine for the asking. Planning for my next step and can’t afford to be vague.
