Here’s a nifty little gadget from the crew at …Lost surfboards to help you dial in your next board. Read all the info below or to play around with the Guild Factor (the one that actually works) go to CLICK HERE.
DIAL IN THE PERFECT FLOTATION FOR YOUR NEXT SURFBOARD
1. Choose your body weight by sliding the lefthand bar.
2. Next, slide the righthand bar to the perfect volume for your new board by placing the blue dot on your desired GF Ratio.
Recommended GF Shortboard Ratios:
– Advanced, extremely fit, high performance surfers: RANGE FORM .34gf to.36g
– Typical fitness with average, to above average skills: RANGE FROM 36gf to 38gf
– Domesticated, lower fitness, desk jobs, and Weekend Warrior surfers: RANGE FROM 38gf to 42gf
– Novice surfers, or surfers with extremely small surf, thick wetsuits or adverse conditions: RANGE FROM 40GF TO 50gf (depending on age, ability and motivation)
*If you’re surfing in warm water and good waves, the lower end of the scale is recommended. If you’re surfing in poor conditions, looking for help in crowded situations, or wearing thick wetsuits, lean towards the higher end of the range that you fall into.
More about GF (Guild Factor)
GF measures the ratio between the surfers body weight and the volume (in Cubic Liters) of a surfboard. The GF number is the percentage of volume (floatation) to body weight. If a surfer knows his weight, he can scroll up and down the scale to find his recommended volume (keeping in mind skill and fitness). If a surfer knows the volume of his favorite board, or a board that feels too floaty or not floaty enough, he can use the chart to guide him in a better direction. As anything, this is simply another tool to make things easier when choosing a surfboard. Its not a means to an end, and nothing is set in stone. Ultimately, the surfer needs to use what feels best for himself.
