I bought a boat unseen and had it transported 04 MC X2 with 33hours. I actually felt better about the transport than buying the boat. I saw digital pictures, had it taken to a dealer, inspected etc. I love the boat but all the "little" things bothered me, ie. scratches, marks, small tears, stains, bent or dented items, it just showed that it wasn't taken care of as well as I'd liked by the previous owner. I saved money, but spent on the boat anyways.
As for the shipping, I posted it on uship.com (it is a lot like ebay for transport) they bid to win your business, you can tell them if you want it towed or trailered, inside or out. You can communicate with them via email before you accept their bid. It gave me enough confidence to give a boat to someone to tow from GA to ID.
