Saratoga: No point in me discussing chest size, since battleships will always be have bigger boobs than us carriers. Yes; go on, insert flattop joke here...
Legs; on the other hand, I actually have something. For example. Jersey and myself: MY legs are a tiny bit longer than hers as I'm just a wee bit taller, BUT while my muscle tone is pretty damned good (I can generate 180,000 shp!) Jersey and her sisters have me beat. They can generate 212,000 shp! So yeah, reluctantly I have to give it to Jersey that she's got the best legs a shipgirl ever had. I'm still a little faster because MY legs aren't carrying around that big armor belt she's got. (Seriously that girl has quite the abs!) Nor *sigh* those massive cannons.
Nuke boats bring some really odd calculations into the mix. They have immensely strong hearts and I like the marathoner analogy: HUGE endurance. But that's as long as they aren't in combat. THEN they can tire out just like the rest of us and eat just like we do to replenish all the OTHER stores that get depleted. Nukes also have a thing for spicy foods. Habaneros and even *shudder* Ghost chilies! Nagato and myself do not tolerate spicy foods well. (Note to Ashigara... If you had done your homework, you would have known better than to serve spicy curry to one of us 'Bikini Girls' ) Curiously, while nuke boats can generate HUGE amounts of power, their ability to channel it into movement is restricted. Someone pointed this out to us recently that all those stories of nuke carriers doing 40+ knots really don't add up when you realize that the actual drive systems aren't as revolutionary as the power system. It's still steam power no matter how you get it, so nukes don't have like 'bionic' running or anything like that.
By the way? Now that I think about it... Would not chest size be a better indication of 'flotation' rather than gun power? When it comes to guns, I've seen Jersey's arms. And there's no competition there. A carrier like me knows when she's out classed.
