S45 Construction adding the rails p-21

Photo 21 shows adding the rails. Notice that the rails are made of two pcs. 1/4X1/8 for the first one and then 3/8X1/8 for the second. You need to start both at the transom. Start at the transom with the rails and stringers. Start one side and go forward to station 9 or 10, then do the same on the other side. Then go all the way to the front with one side. Starting both sides at the same time keep the transom from twisting.
