Thistle Mainsails

Thistle DT-5 Mainsail

The DT-5 is a great All Purpose Mainsail. It is relatively flat and especially straight in the back end. This allows it to be sheeted harder without stalling. Great in light air/ flat water, or big breeze, the DT-5 does it all. New in 2012 was a change in cloth to a proprietary Dacron developed for the Olympic Star class. It has proven very fast and durable.

Thistle TJ-7b Jib

The TJ-7b is one of the biggest sails on the market. This translates into more power in the rig. It is sensitive to jib halyard as conditions change, but this versatility gives the sail a wide and forgiving groove.

George Szabo

George grew up in San Diego racing Stars, Lasers and Snipes. As a kid, he made sails for his model boats before eventually taking a part-time job with Quantum during high school and college. He came on full-time in 1993 as a sailmaker and designer.

Using the latest computer design programs, George is able to create the fastest, most efficient sails for smaller One Design boats. This technology, combined with his intimate understanding of One Design sailing, allows him to create the most versatile sails available. The San Diego loft designs a variety of One Design sails, including Thistle and Lido 14, but their specialties are Olympic Class Star and Snipe boats.

George is the 2009 Star World Champion, as well as an 21-time National/North American Champion. In addition to his sail-making abilities and wins, he is also an accomplished keelboat tactician and trimmer.

Mark Reynolds

When Mark Reynolds walked into the Opening Ceremonies at Sydney’s Olympic Games, he made U.S. Olympic yachting history as a four-time consecutive Olympic representative in the same event. Well-known as the “Star of the Star class," Mark has won two world championship titles ('00,'95) and three Olympic medals (1992 Gold,1988 Silver, 2000 Gold) in arguably the most competitive One Design class in the world.

Mark started sailing with his father (also a Star World Champion, sailing with Dennis Conner in 1971) when he was four. As a sophomore on the San Diego State University sailing team, he was an All American, leading the collegiate team to 2nd place finishes in 1974 and 1975 in the North American Dinghy Championships. A protégé of Dennis Conner, Mark started his first Olympic campaign in the Flying Dutchman class.

After the 1980 Olympic boycott, Mark started sailmaking at North Sails. Two years later, he left to start his own Sobstad loft, then joined Quantum Sails before the 2000 Olympics.
