US flagged manning requirements

If buying a US flagged tug that is overseas. What amount/licensees need to be US citizens?? To operate foreign only? Also is there a grace period before it must be transferred to a foriegn flag (able to operate under US regulations)?? Just have a jbo opportunity and would like some input as to what to expect. Thanks.

The flag state determines what percentage needs to be nationals, but a US flagged vessel must have a US Master. I don’t understand about the grace period. There are several implication when a US vessel goes foreign and that is determined by the flag state.

I don;t know about towing vessels but US flagged fishing vessels only require US master

Is there an echo in here? Is this the shadow of another identical thread by the same guy?
