Swimming Sail Raft

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.

Swimming Sail Raft

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.
