It's very difficult to name a boat - took us nearly as longs as it did agreeing the specification!
There several name threads on here which may steer you towards
from certain things. There are also some websites with lists of registered boat names
There's also a balance between witty & humorous, and naff and offensive - but that line's different for individuals.
At the end of the day it's about you and your connection with the boat - not easy.
Just don't pick something that you'd be embarrassed to hear as a radio call sign
Good luck - let us know what you finally decide
