A good Yacht/Sailing Club is the grass roots to any form of sailing. If the majority of people are friendly enthusiastic and forthcoming with information then what ever boat is sailed the members will feel very positive and upbeat whether sailing an Optimist or Tornado. Maslow, Hertsberg or Katz is a bit deep for me but give me a pint or two and I can sing the virtues of Sailing... and as for a good 'Class' then thats not going to be easy as we all have different agendas. Somebody famous once said you can please some of the people some of the time but you can't please all of the people all of the time. Everybody makes mistakes (don't I know it) and so do Classes. My personal expierence of some of the UK Classes is that they get so big they forget the little people and the worm always turns. Luckily for us if the worm turns there is always somebody who will put them back on track.
