VOLUMETRICS by Whitney Guild
Letter to Surfboard Designers and Salespeople:
I’m writing because I’ve come up with what I think is a new and very important aspect of surfboard design. VOLUME RATIO TO RIDER WEIGHT. Many Shapers are now using CAD programs to help design their boards and can provide volume numbers on each of their different designs.
At the “Sacred Craft” surfboard show in 2009, I gave a seminar on VOLUME and how it relates to your quiver. Shortboard, funboard, longboard or SUP.
I set up my volume tank at the show and was able to measure the volume of over 40 boards by submerging them in my calibrated water tank.
We all know that length, width and thickness are the primary numbers that describe the dimensions of any surfboard. These numbers as well as the rocker profile, plan shape and foil of the board are all key ingredients and must be blended properly to create a “Magic” Surfboard.
There is one more number that also will describe the entire board and how it “feels” in the water. That is the VOLUME of the board, also known as FLOTATION. This is usually measured in Liters. What I have come up with is a certain aspect of surfboard volume and how it relates to your body weight. I call it the Guild Factor (GF), and it can be utilized for any surfer at any body weight to dial in the correct board for the desired function. In the metric system, 1 liter will float 1 kilogram of weight.
I believe this aspect of understanding VOLUME, also known as FLOTATION, will really help customers dial in the best board for themselves, especially for new surfers and also experienced surfers that understand their own volume numbers.
Examples: Jamie OBrien rides a 6-1 at 27.5 liters, he weighs 81 kilos so he’s riding 34% of his body weight (GF .34). I weigh 80 kilos and my performance longboard is 72 liters= 90% (GF .90), my SUP is 106 liters which is 130% of my body weight (GF 1.3).
