Zonker regarding the cargo hold frames: That is the actual structure supporting the plate. I once told him in a Youtube comment that they were very silly with the huge cutouts so they'd collapse if ever loaded. He was not appreciative of the suggestion to change them.

Its not uncommon for hull strength to be misunderstood and for some reason the cargo hold frames got a lot of attention.

Frist off, they are not even needed. The frames not not part normal Origami boat plans. And no Origami steel boat has ever been known to have suffered structural failure.

The frames were added to Seeker as an extra measure. They do stiffen the hull sides, but they more importantly attach to the frames in the keels helping Seekers ability to withstand a grounding in rough seas.

And yes the lightening holes are on the inward side of each frame where compression loads would be greater but they were not cut to save weight. They were cut because they are beautiful and provide attachment point for tables, equipment and securing cargo.
