Framing

Framing

Origami boats are sometimes referred to as "frameless".

In fact only the assembly is frameless. The boats themselves are longitudinally framed.

The following study shows the effects of various framing styles on the resulting strength and stiffness of the plating.

It can be seen from this study that increasing the height of the frames provides the best result, but uses up the interior space.

"T" and Angle bar style frames are the next best method and significantly better than flat bar.

Hull curvature provides a modest increase in the strength, increasing with the amount of curvature.
