Plans come in two basic flavors: Study Plans and Construction Plans. Study plans are inexpensive and give you the opportunity to examine  a detailed scale drawing of the design. Construction plans are vastly detailed and can lead you through the entire build of a boat. The price varies with the complexity of the design. There are boats that exist as study plans only, and the reason is that the development of a full set of construction plans can take hundreds of hours. If you see a boat that you would like to see developed, be sure to talk to Sam.
