Other than the social aspect it has never appealed to me. Additional cost to gain what? In addition there are no true yacht clubs near where I live or near where I sail. I agree that exposure to cat sailing is good but question whether belonging to a club makes any difference. To me the gap between monosailers and catsailors is very similar to the gap between hikers and mt. bikers, both wish to control the same places for their benefit only. Or compare it to skaters and bmxers, both wish to ride in parks, but not with each other. My 2 cents worth!
