Hey YPC

I Agree that The Channels / Chines add performance value, They might have designed them in for self righting
and maybe not. The channels are not a substantial height that would make much of a difference in weight.
Also, The rails on My New boards are 1.5 times thicker than the plastic models, and they self right fine.
I didn't increase the channel height to compensate the bigger rails.

I really think they act more like a displacement hull, as the boards turn very well.
Maybe it's the opposite in that they work at keeping the board on plane and less subject to having the
hull go into a 90 degree angle that would require self righting ?

No one will know for sure unless Kyosho or Wombarra "Chine in" on the subject.

One thing to look at is this: Why would they have been set in design if they only
were made to aid in self righting ? The boards spend 95% of there time above water
And it's proven that the correct weight of the figure VS Board will automatically self right ?
