I *respectfully* disagree with Bryan's first sentence. SOF's can and have been built using plans. Clark Craft (see link at bottom of page) sells Pearcy Blandeford's (SP?) designs, which many have been built throughout the years and even today people are still building them. Other locations are:

and:

However, these plans are *not* cutting edge designs, by a long shot. If you want to build a kayak in the traditional manner or be a bit more cutting edge, then Bryan is correct, you don't get plans, you get instructions on how to do the things necessary to make kayaks in general. It is up to you to adapt them to your needs. I will also make one more addition to the recommended book list that Bryan gave, George Putz's _Wood and Canvas Kayak_. His book is between building from plans and building using the traditional paddler's body measurements. Admittedly, I only have Putz's and Morris' books.

FYI, my dad and I built two of the Canvasback (first link) and modified it to 14' long (did not have the King Canvasback issue of MI, see second link), back in 1986, I was a sophomore in HS at the time. They were very nice to paddle around, but we did not use them much. We made the mistake of covering them in fiberglass (FG cloth/FG matt/FG cloth sandwich) that made them extremely heavy. I am planning on building my next kayak using one of the Clark Craft plans, I really am not after building the cutting edge kayak like a lot of others here.

: SOF's are not built to plans or "blueprints". per se. They are
: built using a basic construction method and dimensions taken from the
: paddler's body. There are three popular books on the subject - from
: Morris, Starr and Cunningham - that take you through the entire process.
: You can see them at the link below. Any of these will do the job, but I
: recommend reading more than one in order to gain additional perspective on
: the process. Petersen's books are also excellent, but they lack some
: detail in the process, so are better suited to people who've built an SOF
: or as secondary sources of information. Boucher's videotape is also
: instructive, as it allows you to see the process from end to end. I found
: his methods rather crude and don't use many of them, but I still thinks
: it's a useful reference.

: The Greenland Forum on the Qajaq USA site is a terrific source of SOF and
: Greenland paddle building information.
