Pyramidion - H.M.S Naked Wombat
Because, lets face it, Wombats are freaking awesome and the idea of a naked one is bloody terrifying. In all honesty, I have no idea where the name came from, it just poped up in my head.
Goldfish - The Doily Blanket
Because the Carronade Setup I tend to go with turns the enemy's Bloon into one.
Squid - Belle Shamhartoth
After Bel Shamharoth, an eldritch horror from the Discworld books. She's a Lady, hence the Belle.
Junker - Rubbish Bin
Shouldn't need any explanation, but also because I don't know how to fly one properly, thus a Junker flown by me definitely deserves the name.
Spire - The Surly Queen
After a webcomic I read, it just seemed to fit the ship.
Galleon - Sixteen Tons
After the song by Tennessee Ernie Ford, because she's a big girl.
