A colleague was in my office wondering if Captain Cook's ships are in WorldCat Identities. Sure, they are. Here are the ones I found:
and Endeavour (suggested by Debbie below).
In honor of Darwin's 200 birthday here is the HMS Beagle. And of course the Titanic.
If ships, why not spaceships? The key word is spacecraft:
There are even imaginary space vehicles (e.g. Rama).
Mostly people write about ships, but under AACR-2 the ships themselves can be considered authors (e.g. of their logs). If you look at the LC/NACO authority record for the Hubble Space Telescope you will see it established as a corporate name. Which almost makes sense! Rama however, is established only as a subject, so it can't author anything.
