Avanti Sails

Avanti Sails are a new generation of sail technology applied to Windsurfing sails. The goal is to make the best sails in the world sparing no costs. The result is string technology sail cloth that is molded with the fewest stitched areas possible. This makes the sail extremely strong and lightweight. Avanti Sails is relativly new in the sail industry. The search for new materials and new design approach to windsurfing sails accomplished sail designer Dan Kaseler and former world speed record holder and world cup racer Finian Maynard began their collaboration to start Avanti Sails. Isthmus Sailboards continues our commitment to offer the Avanti Sails and mast to our customers. We believe Avanti is a product line that fulfills our goal of providing the widest selection, quality, value, innovative and performance oriented gear to our customers.

Together with their 40-years of combined experience, Kaseler and Maynard bring an outstanding skill set and lasting passion to the windsurfing market. Between 2003 and 2005 Maynard made sailing history by breaking three WSSRC speed sailing world records using Kaseler's sail designs. Smashing the outright speed-sailing records, while bringing the title back to windsurfing after an eleven year absence, is still considered a major milestone in the sport of windsurfing. These historic successes resulted in a longtime friendship between Maynard and Kaseler, and serve ultimately as the foundation for the Avanti ethos. Avanti was not created by these two alone. Countless forward-thinking persons got caught up in the excitement and promise of the Avanti movement. Many great engineers, technicians, and supporters were irresistibly intrigued by the question of what could be created if one dared to venture off the beaten path. Each helped grow Avanti, pushing our technologies into the realm of tomorrow. Debuting with the lightest, most sophisticated sails and masts on the market, and structured around an innovative modern distribution system, Avanti can already be considered a leader in windsurfing racing technologies.
