I am having a boat shipped as we speak. The boat is 38 feet and is being shipped from Maine to Maryland. I was quoted a number of prices depending on what was required. The trucking company was able to get a return ship so the costs worked out roughly like this. $1600 to load and unload the boat, on the trailor and ship to Maryland assuming the boat is less than 12 foot beam (she''s 11''-11"). If she was 12 feet in width or more than 12 feet in width, she would need a "Wide Load" car. That would have added $600 taking the costs to $2200. If they had not gotten a return shipment the cost would have been $3200. The company that I used has a hydraulic trailor so they actually can pick up and put the boat down without separate equipment so they were quite competitive with some of the other options that I considered. If the boat is in a boat yard (which the boat I am buying is not) a hydraulic truck is not necessary and normal hauler may be cheaper. I think I got a pretty fair price from the trucking company that I am using. There was a slighly cheaper (and more expensive) outfit that I had talked to, but these folks seem very professional, they had the equipment to pick the boat up and deliver her in one operation and were familiar with the boat and its prior owner.
(Anybody shipping a boat in or out of anywhere near Maine please feel free to email me because the folks I am using really seem great.)
