Well, you can't get much closer then the Hayling Island Model Boat Club (of which I am a member). We sail twice a week at the Mill Rythe Holiday Village (their old boating lake, but H&S and the almost exclusively crusty clientele has put paid to that). Whether it is "suitable" or not is up to you! It is a pretty small club, and has suffered a few losses in the last couple of years, so would welcome some new blood. We don't organise formal competitions although we have some informal sailing races once a month (Victorias and DF 65s)and a rather irresponsible electric powered charge around the buoys (not at the same time!). No real rules, but nobody's been sunk - yet! No IC and no proper Fast Electric, but other than that we have a pretty broad spread of boat types. When you get here, give me a shout and you can come and see if it appears "suitable"!
