Craft a Coracle
(Page 3 of 3)

With the frame on sawhorses and using a heavyweight No. 10 sail maker's canvas, stretch the canvas over the frame and temporarily attach it with metal clamps. Then trim off excess material and roll the edges up to the willow gunwale. After adjusting the clamps to get the canvas folds evenly spaced, stitch the canvas to the gunwale using waxed linen thread, triangle-shaped sail maker's needles and sail maker's sewing palm. I find I often have to use a pair of pliers to pull the canvas as tightly as possible.

After the canvas is sewed on, make up a waterproofing mixture (see "Waterproofing," below). Using a paintbrush, apply a thick coating of the mixture; with a piece of spare canvas, rub the sealant deeply into the canvas. Let this dry overnight and repeat the process again the next day. Then give the coracle two coats of oil-based deck paint.
A final weaving to cap off the gunwale is now completed, and this is lashed to the weaving below it. The final step is the installation of a seat, which is supported in the middle by a single 2-foot-by-2-inchsquare piece of spruce, notched to fit into the ribs and fastened to the seat with a couple of dowels. The spruce seat, 8 inches by 1 inch by 3 1/2 feet, is attached or slung from the gunwales.
Coracles are paddled, or more correctly sculled, not to the stern but rather toward the how using a figure-eight stroke Paddling to the side, as one does a canoe, sends it in circles.
We keep one coracle at the pond and one down at the cove. Some 6 feet long, the latter is the largest I have built so far Mid sometimes transports as many as three of us out to the sailboat. It makes a great lightweight dinghy because of its exceptional buoyancy, and it's able to handle rough seas.

Waterproofing
To make 1 gallon of sealant combine the following: 43 ounces boiled linseed oil, 21 ounces paint thinner, 34 ounces porch and deck enamel, 2 ounces Japan drier, 6 1/2 pounds silica (obtained from a potter) and 2 ounces spar varnish. These ingredients can be obtained at art supply or paint stores.
