Seems to me hake, or some such name has a 30 some odd foot boat that is 8.5' wide, so no permits for width or length. Bob Perry has a 40' boat call a container boat, it will fit in a 40' ocean container, so it would fit on the road also with out length or width permits. Just a proper trailer.
Other options include some boat trailers that allow the boat to sit on an angle. J105's get moved about this way, still fit with in the max 8.5' width on the road, so again, no need of permits!
Just a few other options! Altho they may put you over your budget, depending upon what the budget is!
She drives me boat,
I drives me dinghy!
