If you have a race boat you may have to change the name every race!
E.g you are in the pub, get talking to local business man, tell him about your sport, after a few beers you get him to write you a cheque in exchange for his companies name on boat for the next meet ...and so on.
We called 3 of our boats Ciao! but always listed it in "Runners and Riders" as the main sponsors name.
P.S did u get any more info on your P21?
