Quotes about the Viper 640 from marine professionals and personal sailors around the world…

One-Design classes begin with a boat, but succeed because of its members. The Viper 640 class is riding a wave of enthusiasm that may never reach the beach.
— Curmudgeon, Scuttlebutt

The Viper was great fun to sail in all conditions, fast responsive and controllable but not without a bite when we got it wrong from time to time. While the racing in light wind was tactical and rewarding, there is little to compare with “sending it” downwind in 25 knots; it is what we sailors live for and the Viper delivers that adrenaline rush by the bucket full.

Nick Jerwood, Perth, Australia – 2018 Viper 640 World Champion

What a great regatta (2017 NAs) and we’re thrilled to have won. I really like sailing the Viper 640. It has great tuning capabilities and is physical enough to know you’re really sailing. And the competition in this Championship was excellent with great event management, stellar conditions, and wonderful people to compete against. I look forward to doing more Viper racing.” 

Marcus Eagan, New Orleans, LA, 2017 North American Champion

I’ve raced other one-designs, but this has been the best, most fun boat on the planet, and the people sailing Vipers are fantastic.

Geoff Ewenson, Annapolis, MD

The most fun I have had racing one design in my entire adult life.

My wife drives, my son crews and I do tactics.

With regard to the performance difference between the 20’s. The Vipers are faster, period.

David Hammett, Melges 20’ sport boat owner and Viper connoisseur!

The Viper 640 is without a doubt, a sweet sailing boat.

Betsy Allison, multiple Women Sailor of the Year

It was great to windward, but once we turned downwind I was convinced. I wanted one!

What a great boat and a fantastic class the Viper is.
