# Thread: FOAM - Guild Factor

1. ## FOAM - Guild Factor

I am always checking new boards out online and imagining my next stick. I frequent the Lost site and saw they have a different take on a volume calculator.

http://www.lostsurfboards.net/2013/w...mes-explained/

It recommends more volume than I am used to riding. I have a lost motivator that holds about 35 or 36 liters and that is so floaty for me but good when it's summer or really small. This is the same volume the calculator says I shuold be riding for my short board.

So, I am looking to get a board in between my all out small wave board and my head high+ barrel board and am thinking of a weirdo ripper or something similar, Roberts diamond maybe. I didn't know if I should keep my volume somewhat close to 35 or 36 and hope the rocker and thinner rails will do the trick to fit me into the waves or if I should go lower to like 32 or 33 as the CI calculator says for the weirdo ... I have also checked the firewire calculator and it is too broad.

Really what is your opinion on this calculator and others. I don't see a common number for any of these.

2. I don't know how a simple equation can tell you what you should be riding. It is a total guess and I think its totally unfair to the consumer.

Best trick is going to your local shaper, bring your boards you normally ride and tell him what you just wrote down.

I'm 225lbs 5'10 calculate that.

After crunching all of the numbers..(it wasn't easy) I calculate that you are fat/obese, or overweight(to be more subtle). But you might still rip. Are you Chino Surfboards? I'm good at math

4. BTW Franny. I mean no disrespect. I could afford to drop a couple too. Swell on tap for tomorrow, get pumped!

There's a lot more factors then just height and weight, unless you are tourist and just looking to rent a board for the day.

Yes.... go to your local shaper (one that knows what they are doing) and talk to them. Besides the height and weight, you need to tell them TRUTHFULLY about your surfing abilities. Also what are you looking to do when you are surfing? Another big factor is where you surf. Wherever you surf or frequent the most is what you want your board shaped for. You wouldn't shape a custom gun if you lived in Florida right?! If the board is for a trip then let him know where you are going and what the current conditions have been like there. If where you are going has really been pumping and is a wave of substance then you may want to beef up your glass a bit. If you're not planning to travel at all and live in say Florida then you want to be on the lighter side and don't need extra glass.

If its possible ask the shaper if he has something you can test drive to maybe narrow down your options, or maybe a friend has a board that you like, ask them if you can ride it for a few waves.

Whatever you do don't just buy a board for the name. Believe it or not a lot of these "megabrand" boards are actually shaped by local shapers. You can get the same exact board without the inflated price.

I wonder who thought this one up? I'm guessing someone who adheres to the philosophy of "Blind them with BullSh!1."
actually, i'm gonna disagree; i think this could be a great tool for a lot of surfers who are having trouble dialing in their dims & volume. they can take what they've been riding, volume-wise, & see how it relates to their weight. most recommendations i've seen suggest having about 0.3L per kg of body weight. for me at 190lbs, that puts me at around 26L...ridiculously low. i prefer to be more around 32 or 33L, which is closer to .37 or so.
& the idea that this is only applicable to ...lost boards? c'mon...

for some reason, a lot of surfers are scared of having too much foam or volume, but the truth is, for the vast majority, more foam is going to help them have so much more fun & catch more waves. anything that's going to help surfers be more knowledgeable about future board purchases & what will or won't work for them gets my vote.

my volume from good wave hpsb to uber-groveler varies about 1.5L or so. don't stress about it too much. if what you're riding is working for you, great. if not, a little more volume might be what you need. i prefer firewire's volume calculator as it's the most in-depth one i've seen & the more info you can feed into any calculator, the more accurate it's going to be. ci's is laughably pathetic.

8. hmm...maybe i'm the one not understanding this.

9. How can I figure out my board's volume?

10. so i had a pretty interesting & enlightening email conversation w/ Whitney Guild the other day after he emailed me about this thread.we conversed back & forth a bit & here's what he had to say:

"The Guild Factor was created to make surfboard selection a level playing field for surfers of different body weights.
The selection of one's surfboard should be directly related to one's body weight. Also in consideration should be your ability, fitness, age, and type of wave you ride.
Shortboarders that are fit and riding hollow waves, should be GF .34 to GF .37. Shortboarders less fit or riding softer waves, should be GF .37 to GF .42. Novices should be between GF .40 and GF .50.
This is across the board, for all surfers of all body weights. It is simply a ratio of your surfboard volume in Liters to your body weight in Kilos.
This will allow surfers to choose their surfboard volumes within 2 to 3 liters and will allow a larger surfer to compare his board's volume ratio with his smaller friend's board in direct proportion. If they surf the same surf spot and have similar abilities, it creates an even comparison.
Of course, length, width, and thickness are very important parts of choosing a surfboard, but volume should be just as important.
