Hi Sandy
The club I belong to in CapeTown is the Western Cape Model Boat Club – we utilise a small lake in the Durbanville area (Sonstraal dam) which unfortunately is in chaos at the moment as it is being dredged. We normally sail every first and third Sunday of the month.
There is another club only for IOMs which utilises Milnerton lagoon – sorry dont know too much about them as I’m not terribly interested in çompetitive racing. There is (or was) another group for i/c racing but I think they’ve been driven underground by the noise restrictions.
Hope this helps – drop me an email if you want phone numbers etc.
Cheers – Pierre
