Lofting the Hull
After the planned vessel's hull is modeled using the carved half model, the lifts are taken apart and measured. The shape of the hull is laid out full size, a process called lofting, on a large floor. From the lofting of the frames, shipbuilders make molds or patterns, which are used to select and shape frame timbers made of parts called futtocks.
