For most well designed sailboats CG is not the first concern regarding seaworthiness. A cockpit full of water may in fact ultimately lower the vessel's CG at the cost of the not inconsiderable reduction in her seaworthiness. (g)
Taking into account the factor of crew fatigue as a matter of seaworthiness, the center cockpit recommends itself in weather. If you'd like to examine this I'll set my teeter-totter up in the backyard and we can do some testing. Lunch will be served......afterwards.
