All_Thumbs has a downloadable/printable paper catamaran you can make – “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.” – Link.
