Doing some Godzilla runs for a windward hull.

 

There seems to be nothing that is "beneficial" about rocker as far as Godzilla is concerned.

 

I'm not debating the real world merit... just there is nothing that I can find that drives a hull in that direction.  Certainly, if I constrain a shape factor... say third factor being:

 

0.3, 1.0, 0.5

 

... the algorithm seems to peg on that lower limit.  If I lower it again, Godzilla always finds a more efficient one at the new lower limit.  To me, this seems that I am over constraining the problem based by my WAG of the minimum shape factor allowed.  Which at the moment is arbitrary.

 

Is there some other way to "encourage" Godzilla toward an optimized design that has rocker AND is based on other "factors"?

 

Thanks,

Dennis
