Freestyle Stripper

Ive just ordered plans for my next boat: an Èlan solo freestyle canoe by Doug Ingram of Red River Canoe & Paddle. Doug builds gorgeous traditional cedar-and-canvas canoes, including this one, and also does some designs, and the Èlan, he says, also works well for strip-building. Im by no means a freestyle paddler, but I have a hankering to learn, and since boats well suited to freestyle arent all that readily available, building one seems to be a good approach.
Strip-building, also known as strip planking, is a boatbuilding method that edge-joins narrow strips of wood to form the hull. It differs from carvel planking primarily in that strips are much narrower. It was originally applied as an economical alternative to the cost of full-width planks when building "full size" boats (like lobster boats), and in such applications, the strips would often be as thick as carvel planks and could be edge-nailed together with glue in between. (Careful, Im distinguishing between width and thickness here.) But as applied to modern canoe and kayak designs, the strips are very thin -- typically 3/16" or 1/4" -- thats too thin to edge-nail, so the strips are simply glued edge to edge. The hulls is shaped over temporary forms, then covered inside and outside with fiberglass, carbon fiber, or Kevlar fabric laid in epoxy. This makes the structure so stiff that no internal hull structure (keel, frames, bulkheads) is needed -- although canoes, of course, have thwarts, and kayaks decks, which add considerable stiffness. The result is both tough and lightweight, and the method lends itself to round hulls with fair curves -- unlike the stitch-and-glue method of boatbuilding, which can only produce chined hulls.
There are several books on strip-building, links to some of which Im inserting below. Nick Schade, who wrote The Strip-Built Sea Kayak, has a new book on strip building coming out soon with McGraw-Hill: Building Strip Planked Boats. Where his previous book covered only kayaks, the new one addresses other types, including open canoes and rowing boats. Nick is the proprietor of Guillemot Kayaks, and he is a craftsman of extraordinary talent – meticulous in his designs, woodworking, and writing.
