A super-secret Australian Navy study, given the title "Boobie Hatch", has revealed that assigning a scientifically determined number of female sailors with breast enhancements (called "floaters" by some of the less PC male sailors) to each vessel would render it virtually unsinkable.

The study further stated that if the enhancements were of the "super-large" variety, it would be possible to assign a lesser number of female sailors to a vessel.

However, the study cautioned that incorrectly assigning too many female sailors to a vessel, could result in the vessel riding too high in the water, rendering the propellers completely ineffective.

The study listed this possible problem under a heading called "Excess Boobage Is A Negative Factor".
