Since Doyle Boston Sailmakers entered the Viper 640 class, no other Sailmaker has won as many races or major events. Team Jackpot, led by Brad Boston has won five North American Championships.
Our current sail designs for the Viper are the result of a full and exhaustive computer design and full size sail testing program that has proven to create fast, easy to trim and long lasting sails for the fleet.
