We needed our 21' motorboat transported from one marina to another. Our shipper was prompt in arranging a date to pick up and deliver the boat, and went way beyond the call of duty by agreeing to put the drain plug in the boat for me (since I had forgotten to do it, and since this marina stores boats to stack storage from the water), and he also went beyond the call of duty to take existing rope on the boat and create a front and back tie-up that the marina wanted. It was a very positive experience.
Using the UShip site was a positive experience for us. We would definitely use UShip again to find a provider to transport our boat.
