Howdy folks,
I am no engineer on the subject of fluid mechanics and hydrodynamics, but I have always been curious about why scale models require an increase in rudder size and the addition of heavy keels to help stabilize model sailboats. I think it has something to do with molecule vs. mass. Is this true? Can someone enlighten me here? How do you know how much to increase in rudder size and keel?
I must have alot of time on my hands in retirement, but inquiring minds just need to know.
Thanks,
Dennis
