Besides using the word "wind" in a lot of names when I'm in my "wind naming" mood, I don't really have much of a convention besides labeling the ship hull in front of the name.
Sometimes, for fun, I tease the opponent with a name that one MIGHT be able to figure out...one of those, is naming a ship "Buffy". Buffy is a vampire slayer. So, the ship type is a "slayer" (or Sat Layer...get it?). Of course, naming a mine sweeper "broom" is a bit obvious

. I'd rather name one, "Pledge" (as in a product used for dusting...and dusting off mines is what a sweeper does).
Don't ask Mark the Merciful how he names his ships! I was thwacked by ships called names such as "Pork", "Pork rinds", and "Bacon".
