The premise is this: As much as you'd like too, you can't drive your board equally on your toe side as your heal side, you can't. Your body does not bend the same way. Heel side you loose the flex/power of the ankle flex. Your ass drops in a different position, hips and upper body is different. To boot, your front foot is (almost always) pointed somewhat forward, putting your toes 2\" to 3\" further forward relative to your heel from the tail of the board.<br /><br />Based on the theory that the human body and the way it is designed, when you lean forward, all your weight is transfered to your toes. That's why your frontside bottom turn is easier. The opposite is true about your heel-side. That's why you have to squat more and apply more pressure.<br /><br />So in theory, in order to make the board handle the SAME on the heelside turn as it does on a toeside turn, the board would have to be asymmetric in order compensate for our bodies not flexing/powering the same, to be have the same ride. This was the premise used to design the asymmetric race snowboards. As snowboards got narrower, so the degree of asymmetry offset was reduced until it became neglige-able and commercially nonviable in a shrinking market requiring 2x the number of board models (goofy/regular). But the theory remains sound.<br /><br />The theory is, to make a board handle the same on both turns, you need to move the hip and foil back on the heelside, shorten the rail length overall on the heelside, and give it more curve overall. The rail should also be slightly less boxy. The distance between the center fin and the side fin on heelside slightly less than on the toe side.<br /><br />By shortening the heel-side, it relieves the pressure required to engage that rail. Through years of R&D, I have unveiled my first Aysm. model. \"The Einstein\". The thinking mans board. Not only is the outline Aysm, so is the fin placement.

Asymmetrical's, anybody into them?

This is my type of schitt. Keep talkin BSnydes. I like where this is headed. Innovation.
All things being constant an asymmetrical board makes a lot of sense. That's why you see them tearing up perfect point breaks. I really love the concept and am jealous of people that can actually specialize their equipment to that level, specifically you west coast folks.
East coast folks aren't granted that luxury and have to use adaptive styles rather than adaptive equipment. I think they're sort of the ultra cool fad right now especially if you're going finless even though it goes back to hydrodynamica influences from 50-60 years ago.
I'm obviously out of my league talking shop with you but I like take my design cues from nature. The most dominant and beautiful species are the ones with the most symmetry. It's not until you get into completely isolated environments that you find asymmetrical development as a positive feature in survival of a species.

I ride an asymm fish shaped for me by Rick Malwitz. The backside is shorter and has a sharper radius than the front side with a different rail outline, and the frontside has a single keel fin, the backside a twin fin setup. I ride this in moderate Rhoade Island surf . . . 945679_371422809647474_1566280986_n.jpg
How do these asymmetric boards work in east coast beach break garbage?

Those things have been around for ages. But I have never seen anyone truly rip on them. Great for dudes to talk about but I can't see them helping me make sections, set a rail on late backside takeoffs or weaving through bowls- frontside or backside. Why put a short rail on your heel? To remove glide from my backside bottom turn? To make it feel jerky on said turn? Spread out my top turn when I change rails on the same wave? I say the beauty of surfing and skateboarding is that I'm not attached to the plank except by wax and gravity (unlike snowboards). I can step over here to set the rail on this section and over there for that turn. A good surfer can figure out any shape. I want to see some vid of someone shredding an asym. Get some under the neighborhood legendary beach athlete and record on the same day and wave.
