Lofting is the process of drawing lines of a boat full-size, to get the shapes and patterns needed for building. You take the numbers from the table of offsets, plot them on the floor, and then play connect-the-dots. Okay, it's not that simple. If it were, you wouldn't need the book.
Take advantage of the lower prices of these "hurt" books. These books have been returned, are slightly bunged or scuffed. None of these books are severely damaged, ie; ripped pages, water stained, and the like. They are perfectly readable, useable books.
Please note: hurt books are sold as non-returnable.
