In an effort to explore low cost and sustainable ways of taking to the waves, I have developed this kayak build (based on a traditional Inuit Qayaq), which uses or rather re-uses the most readily available materials. This is instead of relying on expensive and polluting polymers, exotic plywood or even sealskin and whale ribs which make sense in the arctic, but not most other places. My choice of materials then was: suits, desks and computers.
The build uses a traditional 'skin-on-frame' method, which depends upon long batons pulled together at bow and stern and spaced in between with bulkheads. These wooden parts were made from a solid wood desktop. They were lashed together with wire stripped out of computers.
The frame is covered with a 'skin'. I made this from unpicking business suits and sewing them into a large sheet, wrapping around the frame and waterproofing it with an oil/wax mix.
The plans for dimensions were loosely based upon the excellent Yostwerks sea bee. That site can be found through this link:
I searched local shops and house clearances, but in the end had to buy a locally located desk online (through a popular internet trading site). Solid wood desks are not easy to find. You can't use particle board.
Cut the desktop into strips. The size of the desktop will determine the length of the kayak. You will need five or more lengths of wood. I was able to cut fifteen batons from my desktop and subsequently joined the batons into lengths of three giving a total of five bits of wood a bit over 15 foot in length.
one (sturdiest) length is for the keel. Two for gunwhales which edge the deck of the craft. at least two are for the 'stringers' that make up the rest of the hull line.
