Sailboat

How to fold an origami sailboat

Paper
One square sheet of paper.
Preparation
No cutting or gluing is included in these folding steps. Begin with “Fold in half into a triangle”.
What you will make
A sailboat with a sail and hull.

Make an origami sailboat by folding a triangle and creasing the hull in both directions. Open the paper, then form the hull with an outside reverse fold. View the 3D model from the side to compare the layers before and after this fold. Finish by turning the boat so the bottom of the hull faces down.

Follow the 6 steps above by scrolling. Drag the model to inspect a fold from another angle, and scroll back to review a previous step.

Read all 6 folding steps
  1. Fold in half into a triangle
  2. Crease the hull and unfold
  3. Make the same crease in the opposite direction
  4. Unfold the triangle
  5. Outside reverse-fold the hull
  6. Turn the boat with its hull down

Tricky points and what to check

Which crease guides the outside reverse fold?

Steps to review: 2・3・4・5

Crease the hull in both directions before opening the triangle. Compare the first illustration, then follow the lower section turning outward around the sail.

The hull points the wrong way

Steps to review: 5・6

After the outside reverse fold, a separate step turns the hull bottom downward. Review the whole-model turn rather than adding another fold.

Step 5：Outside reverse-fold the hull

Three views from the same 3D folding sequence. Read from top to bottom.
