Lo and behold, I was able to launch 'sharp on a computer where I was staying last night.
I replicated a carrier, battleship, and destroyer that I've simmed in 'style, and didn't notice any profound differences in the output so long as the bugs weren't acting up. However, I was either having a bad night or the version I have is somewhat buggy - things like my seaboat ratings were all over the place, which annoyed me.
So for the moment, I think I'll probably use 'sharp to settle on a "beta" design, then run it through 'style to proof it.
