J/70 Class Info

When the J/70 was introduced, Quantum was tapped by J/Boats to be one of the lead sail developers for the class.

An All-American sailor at St. Mary’s College of Maryland, Scott later coached many students to the All-American ranks at the College of Charleston in South Carolina. He has a wide range of racing experiences, including dinghies, One Design keelboats, inshore big boats, and offshore distance racing.

Kerry Klingler

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.”

Martin Kullman

Martin Kullman grew up on the water in St. Petersburg, Florida, so it’s no surprise that he started sailing when he was only five years old. He continued sailing throughout his youth and at Old Dominion College, where he was a three time All-American and won the national championship.

After graduating from college, Martin joined the work force, but in 2011 his passion became his career when decided to pursue sailing fulltime. He had such a positive experience with Quantum Sails that he joined the team in 2012. “My favorite thing about being part of Quantum is the great group of people who have the same goals and aspirations,” he said.

With an extensive list of sailing experience including TP 52, MC 38, Carkee 40, Farr 40, Farr 30, Melges 32, Melges 24, Melges 20, J/70, J/111, J/88, J/22, J/105, and VX One he brings a wealth of knowledge and experience to Quantum. As the National Sales Director, he strives to provide a courteous and fun experience for all of his customers, and Quantum provides the perfect place for him to do just that.

Jeff Thorpe

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.

Terry Flynn

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.
