Origami Hull

The Origami hull is a hull formed by folding steel into the shape of a hull.  The hull plates are first butt welded to form a two large flat plates. Each of the two larger plates will be formed into one half of the hull from bow to stern.  To form each side, darts are cut into the plate and the gaps pulled together, bending the plate into it's three dimensional shape. When both sides of the hull are completed they are brought together and welded down the keel.

 

 

 

 


Test pattern for a single chine origami hull.

Here is an example of an Origami Boat pattern for a single chine hull.  You can download and print the large image of the pattern, then cut out the pieces and tape it together to see how the process works.

See "Paul's 65ft Origami" for an example of how a large origami hull is built.
