Hey Elminordic - I am just going to tell you this because I hope it makes you feel better (not because I did the right thing necessarily).
I pulled my boat home from Connecticut to Virginia with no plates on either the truck or the trailer, and I didn't even have a title to the trailer for over a year....
3 years later I went back to CT to pull my father's Wellcraft home. We had to take the radar off to get it down under 13'6" (it ended up at about 13'3"). It was 9'10" wide if I remember correctly and honestly barely fit through the tolls.
What sucks is that IF you were to get pulled over it would all depend on the officer. A big risk in my mind would be if you blew a tire or something and had to pull over - you'd certainly garner some attention under those circumstances.
PERSONALLY - considering the size, beam, weight and the fact that you are running an F650 - I would just grip it and rip it and not worry one bit about it. That is probably not the responsible decision but I like to think I can still justify the "young and dumb" card!!
