AN INTRODUCTION TO SKIN-ON-FRAME CONSTRUCTION

To many people, the term "Skin-on-Frame" brings to mind either a bundle of driftwood lashed together and covered with sealskin, or a heavy wooden frame with canvas stretched over it. Most are not familiar with the degree of sophistication that is possible using Skin-on-Frame construction. Centuries ago, the Aleuts developed Baidarkas (kayaks) that were finely engineered with pieces of whalebone let into the joints between the stringers and frames, allowing the boats to flex longitudinally.

The bow and stern were designed to let the skin respond to changes in water pressure so that lamininar flow could be maintained at higher speeds. This reduced the wave-making drag allowing the paddler to achieve higher speeds with less effort. The lightweight wooden frames were perfectly proportioned for strength and flexibility, and there was little room for improvement until the advent of synthetic materials.

Skin-on-Frame construction offers many advantages for the home boatbuilder. Materials are relatively inexpensive, and there is no need for the elaborate forms, spiling, and planking associated with wood-planked boats. One of the chief advantages is flexibility, which allows the structure to "give," instead of breaking under stress.
