Asymmetrical Surfboards
These boards will change your surfing!
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.
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.
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 negligeable and commercially unviable in a shrinking market requiring 2x the number of board models (goofy/regular). But the theory remains sound.
So, in theory, 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.
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.
This design concept is a rational and logical step in producing a board that specifically takes into consideration the differences between front side and backside surfing. As a general rule your backside turns are somewhat more drawn out (larger arc). Your front side turns have a tighter arc and are a little snappier. The goal is to tighten up the backside arc while maintaining down the line projection. Also, your front side cutbacks will be improved as will be you're off the lips (front side). The board is basically 2 boards mated together at the center strip. The front side rail line is the longer side (swallow tail design). Front side turns are easier to make and the arc is somewhat tighter than backside. The front side rail line is pretty much designed for projection and down the line speed. The backside rail (3-4" shorter) has a curvier plan shape (round tail). This change in plan shape produces a tighter arc for better cutbacks and coming off the top. Also the backside board has a wide point that is 3-4" back because of its shorter rail length, this gives the board more of a quick pivot. Fin placement also enhances your front side cut backs and front side off the tops. Overall, this design is meant to help your backside surfing while maintaining the down the line front side projection. Surfers are surprised at the fun and functionality of this approach. I have shaped everything in-between a 5'7" and a 9' long board in this design. They work great!
At my factory, I have two demo boards for customers to try.
My friend, Lorenzo has a surfboard review website. He tried my Aysms. Thought I'd never get them back. He loved them & is spreading the word. Aysmmetrical Surfboards work!

This is the Four-fin version. But actually, one side of the board is a Tri-fin, the other is a Quad.
