The Laser Performance website has Sunfish sails available for $250. Seems like a good deal for an "official" North sail. But racing sails are $535.50 !! What makes them worth 2x as much as a colored sail????? Is the sail window made of some exotic plastic?????? And when you are charging $535 for a sail, why add 50 cents to it to make it $535.50?? Crazy!
