Pontoon shape and Strength

[Oldchuck]

Been looking at both the Round and Elliptical pontoons and got curious as to the relative strength or supporting strength of one vs the other. Given that both are the same thickness is there any wisdom as to the strength of one to the other? Now I know most will say they are both more then adequate but curious from those who may know more then I do about design strength. Any Thoughts?

A look inside my center elliptical toon. You can see a heavy aluminum angle welded to the bottom. I'm sure this stiffens up the bottom but it supports the floor for storage. The other pic , don't know how to explain it. these pics are from the center storage in the front half of the toon. The rear half holds the 55 gallon fuel tank and beilge pump. Not much room to look around

My SPS center storage has similar brackets but I don’t remember the angle in the center

Thanks. This helps me understand how they are constructed.
Was just curious if the Ellips and round were constructed the same...
