<DIV><FONT size=3>Yes, there is a rule. The drop weight must be heavy
enough so that if all compartments were fully flooded except for the main cabin,
the release of the drop weight would cause the vessel to rise to the
surface. "All compartments" includes battery pods and anything else that
could take on water.</FONT></DIV>
