That is the kind of question no one wants to answer ( off the cuff) because 1 if they are wrong it can kill their professional business, and 2 asking means you have a significant vulnerability and you would be a client if someone could nail you down ( and you don't want to be a billable client.) We really do understand you don't want to give USCBP any reason to stop or search your vessel, nor any hint that your paperwork is Out Of Order.

I really think you need to pay up for a professional answer and quit looking under the bleachers. Just MHO. Half a million in boat bucks is not a dingy.
