While in New town, get the white van into the water and push the boat in the water too. Once you do this, have one person drive the van into a corner of the dock(make sure they stay in the van when they get it there). Now have one person drive the boat into the van. If one person is in the van and the other is in the boat, the boat will fly over the van. While the boat is in the air, you need to fly it onto the land, and then you should be able to drive the boat on the land.
