Laying It Out. Using a piece of chalk and a steel ruler, Larry draws guidelines to delineate the tops and bottoms of the letters that will make up the boat’s name. Because the lines are spiled (i.e., made to match an existing curvature via the ruler), the letters of the name, when applied, will replicate the camber of the transom. The size of the letters? Larry “eyeballs” it, making sure the boat owner approves.
