Once again...Is the boat documented? You can't gain US documentation, so it will need another national documentation/registration. And if you put NJ state registration on it, there's no assurance that any delivery crew would be ALLOWED to enter another country with it.
And without any papers...the USCG may not allow it to exit the US, and state officials may present other concerns.
It sounds like you still don't understand that unless you meet ALL regulations, state, national, and international, that vessel will most likely be impounded and taken from you. And the folks who sail it into some foreign country, will be held liable for storage and disposal fees if someone doesn't show up on time to take it back OUT of that country again.
Sorry, Johny, but if you are legit on this one, your best bet is to come do it yourself. Take the train or hitchhike to Brussels, fly a cheap carrier like Icelandic into Newark NJ, and you'll be able to sail it away. If you can't afford that--then you probably can't afford the launch fee and the other expenses.
