This model is not currently offered as a verified ready to buy print.
What it does
- Prints in parts so you can build a working sailboat, teaching how wind and sails really work
- Race your boat in a shoebox of water by blowing through straws, so kids learn physics through play
- Adjust the sail, rudder, and angle to sail sideways into the wind, showing how boats move in any direction
- Uses simple materials like soda straws and plastic, so you spend time learning instead of buying supplies
- Made in the USA from the US design community, supporting makers and educators
Your kids will build a real catamaran and race it across water while learning how sailboats work. This 3D-printed kit teaches physics through hands-on play instead of textbooks.
The boat comes as printed parts you assemble with soda straws and plastic wrappers. You power it by blowing through a straw to move the sail. By adjusting the sail angle and rudder, you can steer the boat into the wind, proving that boats don't have to go the way the breeze pushes them. This discovery hooks kids on how physics shapes the world around them.
Perfect for classrooms, science fairs, or home learning. Each boat races in a shoebox of water, so setup takes minutes and cleanup is easy.

What it is made of
Designs like this print well in PLA. Compare the materials.
Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
