What are the reasons the griffin modfish is so fast? I’ve been surfing a tomo quad fish (from bfeore tomo started doing all his channel bottoms) with a single concave, and while that was fast it didn’t compare to the modfish! It seems counterintuitive that having 5 fins could be a fast design. There must be some other factor at work, is it the flat bottom as well as some other hidden reasons? The fins are foiled nicely (they are his g-10 fins) and there is a lot of nose rocker and nose flip. I caught a wave and did a couple pumps and all of a sudden I was zooming down the line so fast I almost fell off the back.
Wide tail
Low tail rocker
And magic fins
Chandler knows fast
Read the QRQ Quads are Quick thread and a heaping percentage of the reason is explained there.
flat bottom
hard beveled rails nose to tail
constant water releasing outline + bottom+ rocker
same water releasing fin profile built out of material to give it drive
his ciustom G10 fins provide the drive
the rest of his design lets go of the waterflow as efficiently as possible to make to board go as fast as allowable.
GG is all about “release” in everything he sculpts so all the pieces of his designs have fit togethor with that single purpose
i believe there’s a scene in 5.5x19.5 between tom curren and george greenough where george tells tom to imagine he’s the water flowing over the shape as he struggles with his plan shape outline.(MP inspired)
if you wanna ride a bar of soap get your hands on a alexander gemini to play on.
it’ll teach you alot about functional design versus looks.
one of the fastest things i’ve experienced other that GG’s designs
BTW his fish is faster than his modfish (even flater rocker)
one thing to consider…
you only really need the extra speed from the design when it’s not already provided in the wave
otherwise you’re looking more at “controlling speed” when the wave has more speed and power than you can handle.
This is important, thanks for posting Oneula.
I think this is something that I’ve overlooked on my last few boards and something I’m looking to incorporate on the next.

Maybe it's good design and shaping...
Around 40 years ago I shaped a board that had almost no rocker and down rails. Around 6’0" with a wide tail…narrow nose and a huge Greenough style fin. It was actually too fast down the line and I couldn’t control it very well. So whats my point?
Just like they taught us.low rocker…flat bottom is fast. I don’t know about the fin thing. Of course there is the thing about red boards but that is a not widely known.
Every Board is about friction and release. The best board designs are a balance of these to basic concepts. Friction gives a board control and of course release is how you give a board speed. In my Opinion the fin set up is a minor player in increasing speed. It is more how the fins interact with other elements that do allow a board to move across water. The fins main function is to add drag where it is needed to organize the flow of water into something the surfer can use. If there are 3 areas of the planing surface nose mid section and tail there are at least 10 combination or how to make each section work and more combinations or blending each section together. now there is the rails to think about and how they relate to the bottom contours and then the combination of valium in nose, mid section and tail. Now ad to all that the tail it's self. Swallow tail, Round tail, Round Pin, square tail. squash tail and many others all told you may have well over 2000 different combinations to choose from and play with well before we even get to the fin combinations.
As Mike said above, It's good design and shaping.
Thanks for all the answers guys, I learned a quite a bit from the discussion, especially the fact that there’s always more to learn!
