If I found a boat half way or more across the country that, after serious investigation, I really wanted to buy, I'd fly there, inspect, sea trial, and buy it, then rent a pickup truck and tow it home myself to save time, and perhaps money, depending on the circumstances.
Could be a pleasant travel adventure, too, perhaps, based on the time of year, etc.
You'd have to have the wheel bearings and brakes checked out, as well as the tires, and renew as necessary, and so forth.
Often the boats in the mid-west, back east, and in the south sell for less, making the trip more affordable for a west coast buyer.
