Cassiopeia.
Thanks to Anonymous who suggested that the boat ought to have a name plucked from the original series of Battlestar Galactica as I watched the box set during the early stages of the build.
It's certainly better than my first thought - "Mini McBoatface".
Cassiopeia (Biog on Wikipedia) was played in the series by the amusingly surnamed Laurette Spang. There was also a vain Queen in Greek mythology and a constellation in the northern sky.
Naming is as usual, vinyl letters 3mm high aligned over a printed name. I'd have preferred something about twice this size, but these were to hand and I wanted to get on with painting. More on this tomorrow.
