For those who don't want to spend all their hard earned cash or their last little bit of pension money, there is Uncle Al's . You can download PDF files with all the rules and pictures explaining more than you'll ever remember on the water.
These two are truly Two Sides of the Same Coin. Racing Rules is up to date with technology, featuring boats and gear we use today. With Uncle Al's you will get pictures that looks like it was taken from an amateurs home movie while filming the Lochness monster or from local regatta.
Racing Rules vs Uncle Al's
Either one will give you the the complete set of rules you need to be competitive. I personally use Uncle Al's, but if South Africa's currency was stronger I would definitely have Rules Master shipped to me within a 48 hours.
