At Indian Point Nova Scotia, young boatbuilders from Maine were recently presented with a collection of half-models, and then schooled in a seldom employed style of developing the model's lines into a full sized vessel. The first edition of this book would never have sold out and we would not be issuing a reprint if a respect for craftsmanship and a desire to understand traditional ways did not exist nationwide. The present edition differs slightly from its predecessor. A new series of drawings compliments the existing discussion of lift half-models. The additional sequence describes the building and utilization of sectional half-models.
