First, bolt slabs of polysterene covered in Aluminium sheet to the boat trailer. Fit a car size jocky wheel to the front, Strap the boat to the trailer, point over the edge of the hill to the sea, hop in and hold on real tight. When you hit the water drop the engine and head for deeper water. Drop the anchor on the TRAILER, untie the boat and reverse off.... Great way to spend a day on the water.
