The Viper has even inspired its own vocabulary. You don’t sail, you go “Vipering.” Your fellow competitors are “Viperers.” And when Scott is giving the hard sell to a prospective owner who wants to know about the boat’s costs, he gives a lecture about “Vipernomics,” citing the class’s annual sail purchase limits, low running costs, simple sail controls, quick rigging time, and all-up tow-weight of approximately 1,000 pounds. While Scott is the primary cheerleader, the boat’s popularity has bred plenty of converts. Drew Harper, of San Francisco, fell so hard for the boat, after an hour’s sail, he pressed Rondar to become the West Coast representative. There are now nearly two-dozen Vipers from Long Beach, Calif., to British Columbia. Other fleets have sprouted in Texas, Pensacola, Fla., Savannah, Ga., Connecticut, Canada, and even Tempe, Ariz.
