[PSUBS-MAILIST] Spherical trim ballast

["Brian Cox" <ojaibees@ojai.net>]

Hi everybody!

 

             I was wondering if anyone had any experience with using  small spheres as a trim ballast tanks (18" dia.).  It seems to me that using a sphere would minimize the sloshing effect that you would have in an elongated tank since the center of gravity would basically be rotating about the center point of the sphere.   - Brian
