Well, my class allows you to pick your own sail number (provided noone else is using it), so I chose "42" and was going to call my boat "Don't Panic". Then I saw some others with that name already and switched to "Mostly Harmless". But then Douglass Adams used that as the title of his last Hitchhiker's Guide book (which was totally lame), so I pretty much left my boat unchristened.

If I get another Isotope, I'll probably go for sail number 235 (after uranuim 235). Then I'd call the boat an "Unstable Isotope". Maybe I could even get a "Smilin' Joe Fission" graphic for it.
