Viper 640

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 the last three North American Championships (2011, 2010 and 2009), the 2010 EFG Pan Am Series and 2011 Charleston Race Week.


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.
