So, this is a design forum, so I figured I would spend a bit of time and explain a few design prinicipals with anyone who was wondering what exactly is going on with your board or why your shaper put this curve here or that flat spot there.

This is going to take a long time, so I'll start with the template curves and work from there...
When you're designing the template of a board you want to keep in mind the wave you are shaping it for, and you want to match the curve of the wave to the curve of your board, think:

Twin fish's have a long straight template (wide straight tail), so they are going to work best with a flat faced wave. Whereas a drawn in pintail is going to fit you nice and tightly against the wall of a steep wave (ie; a thumping barrel).

The planing area of your board is going to give you more or less overall lift in any given wave so again; a wide flat fishy tail gives you more planing area which will help you on a slow, mushy wave; and a pintail which has very little planing area wont do well in a mushy wave since there is no tail area to provide lift...but you don't need that planing area in a powerful, hollow wave.

(I realize I'm using extremes of the board design spectrum, but I don't want to go into SUPER specifics and put you to sleep!)

The nose width of your board is going to give you paddling and planing lift, so again, more nose = more planing area = more paddle speed; BUT:
there is a major issue here depending on what waves youre surfing; a wide nose will tend to hang you up in a beachbreak or hollow wave no matter how fast you paddle...which is why nose-less shortboards do so well in beachbreaks; they 'slip' into the wave more than glide into it, you fit in under the lip and won't get caught and thrown.

Bumps, Wings and Hips:

All three of these template changes provide a good pivot point for turning and water release; so the placement of them is very important. In terms of pivoting, youd want to place a wing or bump or hip near the fin cluster and at your back foot, where you pivot off of.

the squarer your tail shape is, the squarer the board will surf!
long smooth templates make long smooth lines, bumps and hips pivot and snap better (in general but not ALWAYS).

an abrupt curve in the tail template can accomplish the same effect, but can be hard to make visually pleasing...

more to come on rails, bottom shapes, rocker, foil and fins in the next few days as I have time!

post any questions you have and ill do my best to answer them!

I don't know if this is supposed to be related only to your type shapes. Old man that I am and no longer able to experiment with cutting edge design, I am still interested. It obviously had a lot to do with the conditions and the size, but Kelly's board for the Pipe was pretty radical for a Hawaii board. He explained the design idea in an interview and said basically it was a longer board design with the nose cut off. The back half of the board looks like a lot longer board. If you watch the vid he is riding it way up for a modern short board. Thoughts??? I saw him at small Con a couple weeks ago riding one of those super short quad Pods.

Well since I didn't get any bites here, there is a good article on the board at Surfline today. I assume it was shaped and designed at the Carp factory. If I was a young gun I would try one for sure. Thought it was intersting how he made the point of tow surfers riding the biggest waves on 5'6"s. He's trying to move there.

What works for Kelly ain't gonna work for many.

Anyone who has an interest in seeing this board up close and personal, it's now on display at the CI shop on Anacapa.

If I could figure out how to embed photos... I would.
