Start taking a sheet of paper and fold it in half downwards. Fold in half again as shown on the second image; make the crease from top to bottom.
Bring corners to the center so that you get a triangle shape with a rectangle under it. Fold the rectangle part under the triangle upwards– flip your origami and do the same on the other side.
Grab the center of the triangle shape as indicated in the image with the red spot and pull both sides holding the red spot out. Flatten.
Fold the front layer up as shown with the green spot flip the origami boat to be and do the same with the back layer. You’ll get a triangle shape.
Pull the sides outwards and you’ll again get the square shape as shown on the first image bellow. Slowly pull the top parts outwards and you have your paper boat!
