When Polaris delivered my RIB (from Canada to Northern California) it was Guy doing the trailering. I know he has personally delivered boats to Sacramento, and San Diego, as well.
The only commercial delivery that I heard of him hiring was putting a 40'-ish RIB on a train bound for Newfoundland(?)
He built a couple of largish RIBs for a whale watching outfit in Hawaii; I never asked how he got them there.
But, I suppose you could still ask.
