Parabolic Stringers

The parabolic template outlines depicted on the following pages are drawn to scale and are representative of the curvature positioning related to the given blank sizes. All templates are named based on their overall length from end to end. When ordering please specify the specific template to be used based on the finished board length. Any short board template can be used in any blank as long as the template is smaller than the blank itself (this does not apply to fish templates). For example, you can request to use the 6’0 parabolic template in the 6’6EA blank. As a general rule the maximum length template that can be used in a blank will be one size smaller than the blank itself (eg. 6’0 template in the 6’2P or the 6’4 tem- plate in the 6’6EA, etc.) We will only use the same length template in a blank when specifically requested by a customer. All templates can also be used in our Superfused EPS blanks.

Our “stock” parabolic templates can be adjusted in or out in the tail to accomodate a narrower or wider out- line. Be aware that all dimensions from nose to tail will be affected when making this adjustment. Upon request customers may also submit “custom” templates to be kept as private outlines. Custom template set up will be subject to a one-time surcharge.

The most common stringer thicknesses in parabolic blanks are 3/32”, 1/8” and 4mm ply (5/32”). The al- lowed maximum stringer thickness used for the 5’11 Fish and 6’4 Fish outlines is 3/32”.
We suggest using the “natural” rocker in all parabolic blanks whenever possible. Parabolic stringers do not react to (or hold) rocker adjustments in the same manner as when adjusted from a center stringer. For this reason will not guarantee precise tolerances when making “custom rocker adjustments” in parabolic blanks.

Parabolic Polyurethane blanks can also be ordered in colored foam. When ordering colored parabolic blanks with different colored rails we require that you order a minimum of 2 blanks (one of each color) as the colors will be exchanged between the 2 blanks.

@fiberglasshawaii who is building what? Very curious about the final product.
Redwood! Now available. #FillInTheBlank
Behind the scenes. #SocialAbsorption
Old-Growth Redwood is now available! Soft, strong, straight, even grain. Redwood has been used in surfboards since the early 1900s, but because old-growth harvesting is no longer permitted, the supply of this ancient wood is limited. We secured a substantial, but finite supply that we are thrilled to offer as a stringer option. It's a perfect choice for a classic design or a one-of-a-kind board. #FillInTheBlank #MadeInTheUSA #FirstQuality
