Engine .21 (3-1/2c.c.)
Suitable for radio control
As a 31/2 c.c. (.21cu.in) racer, the model is very satisfactory. As a steering boat for competitions, it offers great promise. If you put more than 31/2 c.c. (.21cu.in) in it, you may run into problems of trim, because the boat has been designed "on the limit" for the smaller engines. You might get away with a bigger motor, but don't blame the design if you can't!
The Cachalot, by the way, is a fast breed of whale with teeth. To see what the model looks like, detach the four centre pages, trim and align the keys. A full side view has been included for builders who prefer conventional construction with a keel; the shape can easily be taken off this view. The method of construction detailed is, however, simple and immensely strong.
The principle used is the single ply bottom as on several previous designs. This has proved to be exceptionally strong and light in weight as well as being quick to build.
