William D. Jackson/ A simple explanation of lofting--which really isn't difficult!

by William D. Jackson, Naval Architect

You can build better boats by learnng the loftsman’s trade.

If you can do a good job of~Iaying down boat-design lines full size, you can qualify as a mold loftsman which incidentally, is a well paid profession. The job of the mold loftsman is to enlarge to full size and fair certain portions of the naval architect’s drawings (basic designs shown as the lines), so that templates and patterns can be made and the actual form, of the boat obtained with true fair lines. (A line is fair when,it makes a smooth curve with no abrupt change in shape, and is pleasing to the eye.) Making full-size layouts also serves to avoid the errors that occur when dimensions taken are scaled directly from the architect’s small scale blue-prints and applied to the actual construction.
