Frankly, we hadn't considered combining these titles, until asked if this CD would be available, three times in a single week. Thinking about it, it made perfect sense. A lot of boats are being built glued lapstrake these days, and many of those builders would like to be able to do their own lofting. So here you go. The Lines, Lofting combo CD is $5 less than you would spend for the two books, and this is a lot less expensive to ship to you.
Bear in mind, however, that this is intended to be viewed on a computer monitor; you cannot print from this CD.
