Captain, Buttercup chimed, interrupting Mrs. Dobbs. The airlock has cycled and a U.S. Marshal is asking permission to come aboard.
"If you'll excuse me please," I said to my passengers, "I need to deal with this." I cleared my throat and began to sing:
"Dear little Buttercup,
sweet little Buttercup,
My favorite ship's A.I.,
Please permit Marshall D
Onto the deck, you see,
Promptly, oh Buttercup mine!"
Okay, Captain! Buttercup replied with a giggle. I love when you sing!

Gah I hate getting choppy bits stuck in my head at awkward times of day. Buttercup, the Ship's AI of the Pinafore, will only accept poetic or sung orders.
Feel free to have the Pinafore cameo in the con bits, as Captain Corcoran (my protagonist) is picking up fen after his duty with the 'danelaw.
Not sure where I should have her registered from...
History:
She began her service as the Pinnafarina, a luxury yacht owned by a Miami drug dealer. Original design specs would allow her to comfortably tour the Caribbean with 12 passengers, including the captain/crew. Four decks, vehicle bay with room for two automobiles and two motorcycles. Swimming pool and sundeck.
She was in private drydock when the DEA and the FBI raided. The dealer drove his Ferrari from the hold after a running gun battle with agents, ignoring little things like oh, say, the doors?
The damage drove down the price significantly at the ensuing government auction.
Captain Corcoran, as he's currently known in Fenspace, had originally run tourists in a converted Volkswagen Microbus, the Pearl Forrester and made enough money before the anti-'wavium legislation hit to purchase the Pinnafarina and the necessary oddments to refit her as the Pinafore.
