Asymmetrical rocker profiles: aberration, or customization? ;-) All of my boards seem to get a “right point twist”, especially my longboards with the starboard side of the nose rising a bit higher than the port side when sitting on the floor.
This goes back to the Terry Martin 40 minute board philosophy, but sometimes when I’m shaping a board that I’ve shaped before or trying to recreate something that I have seen I focus on all the minute little details and take foam and take foam and take foam…
and we all know where that ends up 
most fun board i have ever ridden was a board i shaped out of a 10 year old blank mold. everything about it was silly and stupid. but fun.
and i have also made a bunch of asymmetrical templates. accidentally hahaha
Aberration :
1) a deviation from what is right, true, normal, ect.
2) mental derangement or lapse
3) Optics the failure of light rays from one point to converge at a single focus
I pick number two.
Smile everybody...... surfing is all about having fun.
and....some of the best boards I've ever ridden came right off the rack. Don't see many articles about rack boards.....
I'm suprised shops can even sell them.....:)
When I saw “Aberration,” I thought the thread was going to be about ghosts… haunted boards or something… Then I thought, well… maybe it’s one of those, "oh… my board has “soul” or something threads.
Then I read the thread and was seriously disappointed.
Are you sure that the aspect ratio is 10%?
Aspect Ratio = span / avg chord = (span^2) / area
For the fin outline you posted: span = 5.00 units average chord = 2.72 units Aspect Ratio = 5.00 / 2.72 = 1.84
An aside: The effective aspect ratio of the fin when mounted on the board will be approximately 2x the aspect ratio calculated above.
If I assume that the thin shaded strip near the base of the fin is the cross-section view of the left side of the foil, and that the fin is symmetrical,
then the percent fin thickness for the foil (for that cross section) would appear to be about 6% (100 x 2 x ~0.1 units / 3.4 units = ~6%)

Math makes my head hurt.

[quote="$1"] One of the best longboards I ever had was nearly given away. It was maneuverable, but had no drive or projection until it snapped just forward of the fins. The extra stiffness & weight of the repair really made it come alive! [/quote]
interesting outcome hmm this perspective on rigidity & heft turns around some of the arguments re flex & lightness for performance-oriented boards
cheers,

B I N G O !
The base foil is 8" long and .8" thick, and is scaled proportionally to the tip. Noserider fin. -Carl
I’ve never met Dave, but I have found much of his writing to come across as him being so full of his own shit it’s mind blowing.
The thing that trips me out the most is what seems to be the notion there is some “right way” to make a board, or the “best” board. Machine, hand, what ever…
I’ve been thinking about some of the “talk” on the ‘The modern short board is a hoax’, and the “Kelly S. shorter is better’” threads. Not unlike this subject, there is the science of why a board works - in general - and that seems to be so complicated the finest of threads here have only spelled out some of the basics, as the interaction between the boards features and the water are changing so rapidly it’s not “easy” math. Yet, my observation is, there is not as much talk as there could/should be about personal preference. How one wants to ride a wave is as individual as the waves and to the applicable extent the boards.
Ok - Thanks for putting up w/my philosophical ramble. (I had to cut myself off… Ha!)
This was the second time the filter thought I was spam… Hmmm…
Test - ‘shit’ Ya know, in case ‘shit’ brings it up…
Yep - guess that ‘shit’ tries not to fly here… I’ll try to remember so I don’t have to fill in the CAPTCHA!!! Ha!

If you haven't, you need to see dane's aberration on his site http://marinelayerproductions.com/

I went to the website, but wasn't sure exactly what I was looking for! Did see some aerial acrobatics, 'tho!
Dave Parmenter reminds me of some architects that I have worked with. As one architect explained to me (referring to another more famous, more arrogant architect)- when an architect gets a little bit of fame, it’s best if he starts acting like a total genius, someone who knows everything, and you better listen to him because everyone else is an idiot, and if you don’t listen to him you’re an idiot too…
They do this because they know there is a percentage of the population that will then bow down and treat him like a genius.
Parmenter is a maker of computer shaped, Asian manufactured, pop out SUPs…yeah?
As a person who has dealt with Dave P. I would like to come in his defense…
Dave makes all his shapes by hand in a container shaping bay in his yard (now moved to town). From that they get the master molds to the china boards(boardworks). So they are hand shapes, until they get to china! He is very smart and a great shaper!(strange at times like every shaper).
That being said, i think the computer should be use to reproduce hand shapes. Not just cut boards for someone who can connect to dots. If this is done then it frees up the shaper to work on new shapes and ideas.
There are people out there that call them selves shapers and cant even make a board with out a computer!?
I hand shape for fun and to create and use Aku shapes to reproduce good hand shapes.
I do not condone SUPs when you can ride a normal board!
sorry for venting

Hey Dutch. I am sorry I even mentioned his name when I started this thread. My point was that his comments were interesting (not gospel, just interesting LOL) - regardless of who said them. I guess some people are gonna take their potshots, and maybe they have their reasons, but like I say, I feel it was an unfortunate byproduct of what I still think were some interesting and thought-provoking comments.
To Huckleberry, No worries… i can agree it is a great food for thought.
I believe in computers… but prefer to hand shape its my fun and thats why i do it …
keep up the good work
