Perhaps he wants to know how both handle in snotty water, I don't know. Calm to moderate seas water it is clear the OL would wipe the Fountain.
But, in heavy seas, wouldn't the O.L. slide around more and be less glued into the water? But the fountain has steps also, so I'd rather be in an Apache or Sonic in a storm at sea. A heavier boat is going to ride better, if nothing else, and it does not have steps. <gg>
