J/105 CLASS INFO

Quantum has been involved with the J/105 class since day one. We’ve put endless hours of testing and refining into our sails and rig tune to help you get the most out of your J/105. Our J-Boat division of designers and sailors continually works on all aspects of our program, injecting new ideas so the progress never ends.

Our latest class main, AP jib, and heavy jibs are fast and durable, and our comprehensive tuning guide makes it easy to set up and tune for different conditions. One of the key components of our upwind sails is how well they work together. The main and jibs are well matched and easy to tune to different wind conditions, with the AP jib designed for 0-18 knots, while the heavy jib performs best in 14-27 knots. Quantum offers three class asymmetricals for different conditions, but they are all designed with the same philosophy in mind – give our customers a forgiving, fast shape that will allow the boat to sail deep angles while maintaining speed.

Give your Quantum J/105 class contact a call to get more information on our fast and updated designs, and find out how we can help get your program on the podium.

J/105 Mainsails

J/105 Dacron Heavy Class Mainsail

Constructed from Dimension polyant 350 HTP, this yarn-tempered sail was developed for speed and durability. The firm finish and tightly woven fabric utilize high-tenacity woven polyester. The finest woven material available, it’s the basis for the sail’s durability and performance, which has been proven on the water. 

Since 2009, we’ve kept the base shape similar, straightening the back to help the sail age gracefully. We build in a custom luff curve to fit each mast. This ensures the proper fit for your rig, which is critical in heavy air, as it is the single greatest factor for flattening your main evenly. 

Includes a full-length Mainsail Turtle with full zipper for easy sail storage.

J/105 Dacron Mainsail

Constructed from Dimension polyant 300 HTP, the firmly-finished, yarn-tempered, tightly woven fabric utilizes high-tenacity, woven polyester. The finest woven material available today, it provides the sail's durability and performance. Relying on extensive on-the-water testing, we improved the performance of our existing designs so they now include more return on the leech for better light air pointing and power upwind, and an increased luff curve in the upper sections for a fuller head. Newly engineered corner patches and batten pockets make the sail stronger, smoother, and lighter. The changes – combined with a more aggressive tuning system – can improve performance in the 10 knot and under range without reducing the sail's heavy air performance. Includes a full-length Mainsail Turtle with full zipper for easy sail storage.

Terry Flynn, a third generation sailmaker, started out in Annapolis, Maryland, where he developed a great foundation for both cruising and racing. He grew up on the family sailboat, cruising all over the Chesapeake Bay. Before he was 15 years old, he made 10 offshore deliveries from New York to Florida.

As a racer, Terry has competed in the Newport-Bermuda, the old SORC, Annapolis-Newport, and Trans-Superior races. His One Design credits include four J/22 North Americans and a World Championship. He’s also won North Americans, Nationals, and Midwinter races on 420s, Lightnings, J/24s, J/80s, J/30s, and Cadets, as well as winning One Ton, ¾ Ton, and ½ Ton Championships.

Growing up around sailors, Terry naturally fell into sailmaking and has never looked back. He’s worked his way up through the ranks, doing everything from bench work to design during his 37 year career. Terry has been with Quantum since the beginning, using his experiences to make sails that help customers improve their racing result or simply get more enjoyment out of their boats.

When Kerry Klingler was eight years old, his father decided sailing would be a good sport for the family to enjoy together. Kerry and his dad learned to sail at the same time, and Kerry fell in love. He started to race competitively at the local yacht club, and by the time he was a senior in high school he knew he wanted to make the sailing industry his career. He dreamed of life as a sailmaker and decided to pursue that dream.

Kerry jumped into the industry and found himself not only making sails, but running a loft as well. While he appreciated the opportunity to stay in the industry, he felt his talents growing stale. “I was designing sails, but no one was pushing me to the next level as a maker or designer,” he said. “I started looking for a position where I could design with a company that was technologically advanced so I could become a better, smarter, more advanced sail designer.”

He found that opportunity at Quantum Sails. As the J-Boat Team Leader, Kerry not only designs sails for some of the largest One Design fleets, he also gets out of the loft to help his clients get the most out of every sail. Though people recognize him as a dedicated sailmaker, he’s also working hard all the time to provide the best service and products for their boats.

“I teach them first,” he said. “I show them how to tune the boat, how the sail should sit on the boat, how to trim it, and more. It’s a pretty comprehensive session where I try to infuse as much knowledge as possible.”

Jeff Thorpe

Jeff Thorpe was eight years old when he started the Leo Robbins sailing program. The instructor told his dad that Jeff wasn’t cut out for sailing, but Jeff went back the next season and hasn’t stopped sailing since. Throughout high school he raced Sabots, Lasers, and Laser 2s. When it was time for college, he didn’t have the money, so he took a job building and racing Morc boats at Pinnacle Yacht Design Group. Jeff stayed involved in the marine industry in a variety of ways, from an Olympic campaign with friends to fixing and rebuilding J/24s at his own shop to working in a sail loft. While working at the loft, he had the opportunity to sail on a J/125 with Quantum sails. Jeff was impressed with what he saw. He contacted Quantum Sails and told them he needed to work for them. Today Jeff works as a sail consultant at the Quantum Pacific loft, giving his clients the attention to detail they need to find the right sails. With his extensive sailing history, he’s more than qualified to help others figure out exactly what they need to meet their goals. “I spent years running offshore racing programs, so I have a fair bit of knowledge that helps me provide my clients with a great resource when they have questions,” said Jeff. “I make sure they understand all the options available to them to help them enjoy their sailing.” Jeff’s sailing experience includes J/70, J/111, J/105, J/125, Melges 24, Olson 30, E-22, PHRF, ORR, IRC, TP 52, Santa Cruz 70, and Santa Cruz 52 classes, as well as offshore catamarans, cruising boats, and racing boats.

Alejandro Irigoyen

Alejandro Irigoyen started sailing when he was 12 years old. His father was a keen sailboat racer at the Yacht Club Argentino, and Alejandro spent his weekends racing and living aboard the family’s wooden S&S Finisterre. By the time he graduated high school, Alejandro knew he wanted to dedicate his life to sailing, so he started studying yacht design.

He started his sailmaking career in 1982 working for Hood, before starting his own Sobstad loft. In 2001, Alejandro joined the Quantum Sails family. “It was a natural decision,” he said. “I shared the same view and goals as the founding group.”

Though he’s sailed in various classes, Alejandro’s expertise includes Optimist, Cadet, 470, Snipe, J/24, J/70, J/105, Soto 33, and Soto 44 classes. Whether he’s sharing his class knowledge and experience, or helping customers organize their campaigns and training, Alejandro’s passion for excellence provides the best service, products, and support for his customers.
