Since 1979, Stretch has been creating distinctive and innovative custom boards for surfing, sailing, kiting and towing surfing.
Born in Malibu, California, he learned to build boards from his father Mike Riedel, a shaper for Velzy Jacobs Surfboards in the 1960s. His wealth of know-how and surfing skills eventually brought him to Santa Cruz where a life-changing windsurfing accident in 1988 left him with partial paralysis.
His enthusiasm for progressive surfing continues daily with technological advancements, team feedback and a passion for building the best board possible.
Santa Cruz, California
Located just blocks from the beach in downtown Santa Cruz, our factory is a prime location for developing unique and alternative construction techniques.
We build each individual board under one roof in the largest dedicated EPS/EPOXY surfboard factory in Northern California. Combine that with an incredibly talented team of riders, progressive designs and a premium California coastline and you get one of the best waves imaginable.
Imitation is not what Stretch does. It goes its own way and pays attention to the foam. Whatever they ride, he wants to make them a board. And block everything else. Everyone should have their own path.
All Stretch boards have historically been constructed from one of two rockers, 3-stage or parabolic. All new boards are constructed from a spherical rocker. Using a section of a sphere as a seesaw. Use the entire waterline of the board up to the nose.
Due to the way the boards rotate. With tri-fins, the low pressure areas around the fin become larger, stabilizing the fins. Quad, the four fins rotate around a central point. it's directly between the four fins...speed doesn't give directional stability to the quads. Regardless of speed, it's the same stability
Everything except the foam is unique to the Stretch construction.
William “Stretch” Riedel has been creating distinctive and innovative custom boards for surfing, sailing, kiting and towing for over 30 years.
This principle of physics formulated by Daniel Bernoulli states that an increase in the speed of a fluid produces a decrease in pressure. Stretch explains how this relates to surfboard design.
For every action, there is an equal and opposite reaction. This is what Newton's third law of physics says. Stretch explains how this affects a surfboard on a wave and how design can harness this power.
