To get things rolling here are mine:
Squid - The Bonny LizNamed after my wife who is both bonny and Liz. She is small, fast, incredibly aggressive, and likes fighting inside her opponents preferred engagement distance. Also the ship is equipped with mostly close range weaponry.
Goldfish - Golden PhoenixBack before the last patch I had flame throwers on either side. I would occasionally ask my engineers to light them up and flap them up and down to simulate Phoenix wings. Possibly due for a renaming as I now have banshees on the side.
Pyramidion - Mo' Dakka Dakka DakkaNamed after the sound an Orkish automatic weapon makes. I put a lot of chainguns and light flack on this ship because I like the sound of the Dakka. I also have the the tendency to ram things and talk like an Ork while flying this ship. The latest build has less Dakka and may be due for renaming.
Junker - Slim JimNamed because its hull is so thin when viewed from profile. Used to counter-snipe Galleons ineffectively.
Spire - Every Shot a KillshotNamed because unless my gunners made every shot a hit, this ship was going to die badly when attacked by faster, smaller, or more durable opponents.
Galleon - Vulgaris MagistralisNamed after the Viking Metal Ballard "Vulgaris Magistralis." It is Latin for either "teacher of the common" or "master of vulgarity" which is pretty fitting either way.
Here is a youtube clip of the song:
