The benefit of an asym is that you get to ride one type of board on your front side and another on your toe side. The trick is figuring out what two types you are going to blend together.
The logic is that an asymmetrical surfboard combines two different boards, one to compliment your frontside, and one that works better on your backside. It’s easier to apply pressure when turning on your toe side because your foot naturally pivots that way, whereas it’s more difficult on your heel side. Therefore a shorter heel side rail makes it easier to turn the board.
This isn’t a new concept,for many years now there’s been a small flicker of asymmetric thinking.
One small shop, Nelson-Ekstrom in La Jolla California made them for years. Ekstrom had the idea patented in 1967, Jeffrey “Midget” Smith made a hook-back that lengthened one rail back in ’63 and Bob Razby shaped plenty in Byron in the early seventies and plenty of people have taken a crack at it since then but for some reason it has never caught on. I’m pretty sure its because of aesthetics out of the water rather than performance in the water. Most asyms look strange.
The two boards I am combining are not too much similar, only the front 1/2 of the board is a symmetrical (with blunt nose). For the toe side I went with the template of a 6’7″ with a very straight design and a large swallow tail. To loosen up the heel side of David I went with a 6’4″ round lite-diamond tail design.
The bottom shape including a vee on the nose that blend in a single concave, that blend with a double concave… but for the 6’4” side the double concave continues until the end of the tail, in addition there has the vee.Instead on the other side (6’7”) the double concave stops in the middle of the fins and the bottom shape of the tail is flat; Since David wants to use it even finless, I have shaped two channels on this side…”
THE FEATURED BOARD DIMENSION ARE: 6’7” – 6’4” x 20”1/8 x 2”1/4
