You live for water sports... you are a waterman(women)
If you claim to do water sports and only do it for a hobby, you are not.
If you do it only in summer or weather permitting or..., and the other time is spend making money for your family, you are a waterman.
if you are lucky enough to get paid to be in the water all the time, enjoying your (our) dream, you are a waterman (with groupies )
If you think you are, or you have been "published', and behave like a dick, thinking you own the ocean or the (surf)break, you are NOT a waterman. You are just an ass! Lonely ,little,......
IMO : ALOHA = WATERMAN = ALOHA
