My point is it is kind of silly to take two completely different 
boats that perform differently and then attribute all the performance 
difference to just one aspect of design.

While the chines may appear to give boat control, appearance can be 
deceptive. However, I am not saying that chines don't effect the 
control of the boat in the conditions you stated, just that you don't 
have enough information to determine whether the chines really are 
what makes the difference. For controllability you also need to 
consider (in no particular order and not exhaustive): the seat, foot 
braces, bottom shape, side flare, rocker, thigh braces, boat length, 
boat width, block coefficient, everything that contributes to 
stability, skeg shape, and with skin-on-frame and foldables: frame 
stiffness and skin tension. By ignoring these you infer that they 
don't matter. The only possible reason they wouldn't matter is 
because they are all the same for both boats.
