The first couple of lines from T.S.Eliot's "The Naming of Cats" pretty much sums it up:
The Naming of Cats is a difficult matter,
It isn't just one of your holiday games; ...
He goes on to explain that a cat actually should have three different names, but we thought one was difficult enough so we're stopping there.
Criteria: short, single word, not too many letters, we didn't want an overt play on words, something that meant something to us (a personal connection) but not too personal as the boat will be in charter.
Short List: we picked a number of names and once we'd decided that we wanted to register the boat in Canada we had to make sure they weren't already taken - Chinook (taken many times over), Indigo, Azure (keeping in the 'blue' theme of our monohull Blew-By-You), Naida, Nyad.
Then, one evening while chatting with Caitlin, she suddenly tweaked that the boat was a 'cat' - she's a smart cookie, that one! The obvious name to her was Mowzer.
Now, if you are not familiar with the children's book, The Mousehole Cat check it out. Not to belabour the point, but Mowzer keeps her crew safe, tames the Storm Cat and is an all-round stellar Cat! (This is Part 1 - you can find the remainder of the story on YouTube)
