Thistle Class Info

Bringing our knowledge of the Thistle together with Quantum's iQ Technology, we have created the next generation of Thistle shapes. To order sails or learn more about what we can do for you, please contact one of the class experts.

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 Headsails

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.

Thistle Spinnakers

Thistle Spinnaker Radial AP

Quantum San Diego has worked hard to make our Spinnakers the best in the fleet. This has resulted in 2 different cuts (both are radial construction). If you want to win the Nationals, you need a sail that can reach. The SC-7 flies when the wind goes forward! Its flatter shape can be a challenge to trim. Both sails are available in different cloths for added durability or performance in waves. Give one of our experts a call for help figuring out which sail is right for your Venue and expected racing schedule.

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.
