1. Order plans from the IDNIYRA for $25
These scale plans were first published in 1981 and still provide a competitive DN today. They were designed through a collaboration of many of the top DN builders at the time. The plans show a wood mast, although sailors racing in top competition use a composite mast today.

Standard sheet size is 11″ x 17″, scanned at 300dpi.

You can print them out at any size you like, however when printed at 8-1/2″ x 11″ these are quite hard to read, so if you can’t print at 11″ x 17″ you split the image in half and print out each half at 8-1/2″ x 11″ and tape the two pages together. In order to make this easier, the images are also available pre-split.
