From the man's web journal:
"I've got to name a currently unnamed cruise ship in Anansi Boys. I have no idea what to call it, and, a couple of days ago, realised that my utter lack of inspiration could do good things for the CBLDF: later in the week, the CBLDF will do an eBay auction where, if you wish, you can bid to have the ship named after you, your loved one, your dog, or even your favourite word. It's not a particularly exceptional cruise ship, nothing much happens on it, and it will only get mentioned by name a handful of times in the book. I'll announce it and link to it here when Charles Brownstein gets the auction up."
For those not in the know, the CBLDF is the Comic Book Legal Defense Fund, a non-profit organization dedicated to preserving the First Amendment rights of comics creators and retailers in the face of a political climate increasingly hostile to many forms of expression. Gaiman sits on the board of directors.
When the link goes up, I will post it here as well.
