Welcome to the Viper 640 Class

The Viper 640 is a high-performance one-design sport boat.
At 21 feet long and only 748 lbs, it combines the stiffness of a keelboat with the acceleration and planning abilities of a dinghy. The design mandate was "Simple, Clean and Effective".  The Viper has a precise and exhilarating feel on the helm, a spacious cockpit for 3 people, strict one-design class rules and ease of launching by ramp or hoist.

The 2013 Viper North American Championships are being hosted by Houston Yacht Club in October 2013.

HYC's commodore, Pat Gibson is ready for y'all. He loves his new Viper and he put on a show at the HYC Commodore's Ball to give us a taste of what we can expect. The Gulf promises to live up to its reputation for big breeze, great parties, beautiful ladies and lots of SHRIMP!

In the meantime, we look forward to seeing a strong Texan contingent at the Mumblehead 2012 NAs this coming September. In order to reduce transportation risks, the Texans fully intend to collect the North American Trophy and bring it home with them.  "Come and Take It" !

Racing Vipers on Biscayne Bay has deservedly been described as a dress rehearsal for heaven on earth. Crystal blue water, breeze from 10-18 day after day, followed by an evening among the bars and restaurants of tropical Coconut Grove. What could be better in the middle of a cold winter??

2012 Arizona Leukemia Cup

Arizona Yacht Club’s Birthday Regatta is like the “Cochella” of sailing… There’s a festival-type of vibe with everyone staying on houseboats or camping in RVs right next to the lake.  When not racing, most sailors can be seen “campfire hopping”, hanging out at the yacht club tent, or watching NFL playoffs at the marina bar.  And, with cell signal a bit weak, it was definitely a weekend “off the grid”.  If I could freeze time to a single weekend, this might be one of them.  Great racing at a fun venue with a bunch of crazy Viper sailors…

Lake Pleasant is traditionally a light air venue… so my pre-regatta planning included the bright idea of down-sizing my spinnaker halyard/retriever to a class-minimum 4mm super-light line.  This was going to be our “secret weapon” as our current retrieval line was pretty heavy and tended to drag down the kite in light air.  “We’ll be super-fast down wind with this tiny line!” was my thought as I packed up #148 for the trip out to Zona.   Turns out, that decision would cost us the regatta!

This past weekend Arizona Yacht Club played host to their annual Leukemia Cup regatta, also known as the Birthday Regatta.  There was an added incentive this year as Ullman Sails Newport Beach sponsored Friday’s Centerboard Challenge.  The Portsmouth, PHRF and Viper Fleets all turned up to do battle for centerboard dominance.  The Viper fleet also included the day as part of their Leukemia Cup series.  The wind was strong in the morning, but the afternoon included a 180-degree shift and light air, which made for an interesting and challenging racecourse.
