Twelve methods of origami navigation

Twelve kinds of origami sailboats are as follows:

Fold a rectangular piece of paper in half along the center line of the long side, at most two centimeters longer than the narrow side. Then fold the two corners of the hem along the dotted line to align with the center line. The extremely narrow side at the top is folded down along the dotted line, and the reverse side is also folded down. Open the middle cavity, push the two corners back, and the whole triangle becomes a square.

Fold the two separate corners in half along the dotted line, and the whole becomes a triangle again.

Open the middle and push the two corners back to form a square. Pull out the two petals in the upper corner. Finally, turn up the lower corner and tidy it up. Fold A4 paper, first fold the width of the paper in half, then fold the length in half, fold the left and right sides inward, and then fold the bottom. The result is like a cuboid.

The right corner part is folded down. 4. Fold the upper right side from top to bottom to left, which is similar to a square, but the two diagonals are not completely symmetrical. Fold the upper right corner down to form a semicircle. Middle fold, right fold, bottom fold! Fold the upper right corner.

Fold the square colored paper in half and press out the crease. Lift one side, fold it, and do the same thing on the other side.

The rest of the edges are folded inward at the corners as the hull. The small side also folds inward like the stern, and the other end does the same. Merge the paper into a trapezoid and fold the two corners of the trapezoid inward. Fold inward after opening, and the two corners do the same. Just fold the sides in slightly.

Prepare a square piece of paper, fold it horizontally and vertically into a rectangle, and open it to leave a crease.

Fold the bottom edge at the dotted line of the middle crease, and then turn it over to the opposite side. Align the middle crease along the dotted line. Fold the four corners inward into a triangle along the dotted line. Fold along the dotted line and align with the center line. Then fold along the dotted line and align with the center line. Stand them in the middle, turn them over, rearrange their shapes, and the boat will be folded.
