As one of the Guernsey newbies I can confidently say that I wouldn't be spearfishing if it wasn't for the thread on here, so you may well get some new members out of it.
I must say though that personally I'd have no interest in spearing competitions, and probably wouldn't join a club either, I do it because I enjoy it not because I want to prove how good I am at it, or beat other people doing it, but to each their own.
Good luck boys, I'll be reading with interest what you crapauds are up to!
