"How many litres are right for me ?" We get asked that question a lot .
Lets have a look at formula they may assist in getting the right volume / litres in your surfboard
The guys over at LuxBarrel brought to our attention to the Guild Factor (GF).
The GF Formula works like this.
Surfer's Weight in Kilograms (Kg) X Guild Factor (GF) for Skill Level
= Liters of Surfboard Volume
To convert into Kg, multiply your weight in pounds by 0.45359237.
Super Fit Advanced Riders Pro/Competitive Levels: GF 0.34 - 0.36
Normal Fitness Advanced Riders: GF 0.36 - 0.38
Intermediate and Older Experienced Surfers: GF 0.38 - 0.42
Casual Surfers, Old Guys, or working stiffs wanting float to catch more waves: GF 0.43 - 0.49+
Novice Surfer Learning the Lineup: GF 0.50+
If you’re surfing in warm water and good waves, the lower end of your ratio range is recommended. If you’re surfing in poor conditions, looking for paddle power in crowded situations, or wearing thick wetsuits, lean towards the higher end of the range that you fall into.
For example 65 kg shredder super fit in the water everyday , 65 X 0.36 = 23.40 litres.
An 80 kg Older guy feeling unfit and surfer couple times a week at best , 80 X 0.42 = 33.60
Big unit 100 kg not surfing as much as you would like , 100 X 43 = 43 litres
Remember that this a guide only and the type of surfboard model , conditions you surf etc.
Also Epoxy and PU Polyurethane foam has a slightly different floatation and that is a whole another discussion , for another blog post ..
End of the day ask the guys who are building surfboards everyday for some advice ! A few extra litres won't really hurt your surfing , unless you are going for WSL Crown , in fact the extra foam will keep you surfing for longer sessions and that's got to be a good thing , more waves for you !
Above USC Performance Plus , 6'5 by 18 3/8 by 2 1/4 , 25 litres for 67kg surfer .
