Stretch explains his philosophy on surfboard design, trends, and industry perspective.
This physics principle formulated by Daniel Bernoulli states that an increase in the speed of a fluid produces a decrease in pressure. Stretch elaborates on how this relates to surfboard design.
For every action, there is an equal and opposite reaction. That's 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.
Imitation is not what Stretch does. He follows his own path and pays attention to the foam. Whatever they ride, he wants to make a board for them. And block out everything else. Everybody should have their own path. PS Don't get a flyer.
All Stretch's boards were historically built from one of two rockers, either 3-stage or parabolic. All the new boards are built from a spherical rocker. Using a section of a sphere as the rocker. Use the entire waterline of the board all the way to the nose.
Because of the way boards pivots. With tri-fins, low pressure zones around the fin become greater, stabilizing the fins. Quad all four fins rotate around a central point. that is directly in between the four fins...speed does not give quads directional stability. Faster you go, it's the same stability
Everything but the foam is unique to Stretch construction.
