We just have to ask Marcus for the toe-in stiffness to see how much is the result of timber as the material or just the superior beamlanding design.
Remember Wouter the hulls are hundreds of times stiffer than the beams, even if you were to double the stiffness of the hulls you would probably only see a few % increase in the "(beam landing) stiffness" on those tests.
So dont waste your time looking at the hulls for the increase in platform stiffness.
