The
clever and unique device pictured herewith may be made by any
boy who cares to possess one. Study the pictures, for they
will teach you more about the construction than a whole page
of text. The making of the body part is shown in Fig. 2.
It is like a shallow boat and must be covered with watertight
canvas.
A soap box, torn apart, will provide
material for the rudder, as illustrated by Fig. 4. The
sail is three feet wide and five feet long. Tack a stick along
the top and bottom edges, and by means of these cross-arms
lash it to the mast. The mast fits into a square hole and does
not turn. The sail turns around it and is operated by the
handlebar b. A keel added to the bottom will give greater
buoyancy and at the same time add steadiness to the craft.
