Here's another one of the more notorious and instantly memorable Dreadfleet ships - the Skaven's Skabrus.
It's a huge, ugly corpse of a fish turned into a warship by ratmen! What's not to like? ;-) The only thing I find a bit sad about this one is that there is a very fun set of fish guts modelled onto the base as the corpse's "inner decks" which end up being barely visible at all, so don't go too crazy with painting those. The auxiliary cog bears the Skaven symbol on its sail.
