Advancing to this level requires newly engineered surfboard technology. Not just better resins, not just better fabrics, but a completely new engineering scheme. Greg Loehr in conjunction with Segway Composites and Graphite Master is involved with just such technology.
The body of the new blank is a very lightweight EPS foam allowing for extreme lightweight finished boards. The addition of the parabolic stringer arrangement stiffens the rails line, provides desired weight to the surfboard perimeter (controlled buoyancy), and decreases fatigue by reducing dynamic twist. This design creates enhanced drive, better waveface penetration and improves board speed. Because the stringers are parabolic curves, the board is much more resistant to breaking. The rail foam density made of 3 lb density EPS foam, has a lower buoyancy which provides better rail set, a stiffer rail line and increased strength in the boards perimeter.
This dynamic parabolic stringer arrangement sets up some very beneficial engineering possibilities concerning the core foam density. This design isolates the deck and bottom from the rails which will allow the core and rails to be engineered separately depending on the needs of each component, and then different foams and varieties of reinforcements can be used to enhance the performance and characteristics of the completed board.
This unique design will allow for engineering a board where the deck needs dent strength, a bottom break strength and rails ding resistance. This isolation of each component gives the designer more freedom to pursue new avenues into flex and flex return, stiffness verses flex and doing so with lighter weights. This design can translate into smaller more efficient, more powerful, better responsiveness boards, at a far lighter weight while enhancing the durability and creating a board that is more robust while resisting fatigue.
