Cut and fold a sailing catamaran for your nearest "ocean". It can carry a crew of ants, pepples, or some of your sister's favourite (miniature) dolls.
You will need a pair of scissors and an A4 80g/sqm office paper. (No sweat, the design can modified for inferiour formats.) No glue or tape is needed. ...nor batteries.
Step 1: Print or view the drawing, cut the paper to pieces.
The PDF-file provided below contains a drawing.
The drawing is a high precision machine drawing prepaired with programs used by NASA. If it is followed carefully, all parts will fit nicely together. For these reasons, it is recommended that the first one or two boats you make are built from printouts of this file.
Don't cry if you don't have a printer. The design is perfectly possible to follow just by viewing the drawing on your screen.
We start here by cutting the pieces apart along the solid lines. If you want fins, cut them out too. If not, you can leave them where they are. They can be used as a foredeck if left attached to the sail.
