VIPER 640: 2019 PRODUCT DEVELOPMENT

New Class Leader, New Mainsail, Many Upgrades

Viper 640 Product Development | North Sails

When it comes to finding extra speed, extra durability, or better usability for our products, North Sails is never satisfied. That’s why we’ve made important upgrades to our Viper 640 sails that will give you a better sailing experience as well as an advantage on the race course.

New Class Leader

J/22 World Champion Jackson Benvenutti is the new Global Viper 640 class leader for North Sails. Jackson won the 2017 Viper North American Championship sailing with Marcus and Andrew Eagan, and has wins in many one-design classes. “While Zeke Horowitz is sailing in multiple classes, we felt it was important to have Jackson dedicated to the Vipers, a very important class for North Sails,” said Tim Healy, North Sails One Design President.

Jackson will attend the Summer Regatta at the Mobile Yacht Club and the Weatherly Regatta in Gulfport before heading to California for the Worlds in August. After that, he’ll sailhe 2019/2020 Sarasota Winter Series.

New Mainsail Cloth

Our sail designers have recommended a new cloth for the championship-winning M-7 mainsail. We are upgrading the cloth to the North Sails exclusive Xi-18 laminate, which holds its shape longer than the current Pentex®, improving both durability and performance. The new M-8 main features the exact same shape as the M-7, no tuning changes are necessary.

Recent Sail Upgrades

We have also made three improvements to the Viper sails: :

  • Self-attached clew blocks keep the clew from twisting when weather sheeting.
  • Adjustable gaff batten
  • Extended bolt rope to eliminate pre-feeder snags when adjusting cunningham

Enjoy your Viper sailing season! Contact Jackson with your Viper 640 questions.
