Origami Sampan is another boat design.This a flat bottomed boat with cover.The model is simple except the last part where you would have to pull up the cover patiently else it would tear.
I have used standard origami square sheet for the model.For the first timers I would suggest to use a fairly large sheet.
This is one can be termed as one of the simplest of origami instructions.The simple origami sail boat is a 2d design and takes hardly 2 minutes to fold.
It needs a triangular piece of paper.So I took a standard 1 side coloured square paper and folded it diagonally dividing the square into 2 triangle cut it into two and started with one triangle.
The sail boat would look the best if you have contrast coloured paper.The boat can be used for card making something like Bonn-voyage cards..
If you don't want to cut the square but still want to make the origami sail boat then you can follow the instructions at Howcast
.It has both diagram and video for the instructions also the sail boat looks really cool and can stand like a 3D model.I felt the video is really good and easy to follow.
A canoe is a small narrow boat, typically human-powered, though it may also be powered by sails or small electric or gas motors. Canoes usually are pointed at both bow and stern and are normally open on top, but can be covered. In its human-powered form, the canoe is propelled by the use of paddles, usually with two people. Paddlers face in the direction of travel, either seated on supports in the hull, or kneeling directly upon the hull. Paddling can be contrasted with rowing, where the rowers usually face away from the direction of travel and use mounted oars (though a wide canoe can be fitted with oarlocks and rowed). Paddles may be single-bladed or double-bladed.(Source-origami-kids)
Origami canoe can be termed slighty higher than simple in the difficulty level,this is because its not tough to fold but tough to unfold the last part to get the shape of the boat.
I started with a standard square orgami paper and got the boat done in the first go.So I believe its not that difficult.Also a suggestion would be to use a double side coloured/contrast coloured paper to get the actual effect.
I have taken 1/2 of 5 7/8th inch square sheet of origami paper
So to start with I folded the very familiar boat.This is a model which I had been folding from my childhood when I didn't even know of origami.
In a rainy season in the class room during the recess we would make this boat and let it sail over the running water until you get caught by the teacher.
It requires a rectangular piece of paper.As I had squared colour papers I took a 5 7/8th inch square sheet of origami paper ,cut it a half and then took 3/4 of that half to start with ( my boat is bit small).
Another one made out of Post-it Notes of Neon colours.You need to cut the paper a bit to get it into rectangular shape.
