20 interesting statemente re quad v tri

Just like an omellete,that post had everything in it

i really do feel some have closed the door and convinced themselves otherwise, whilst some are happy in their choice and remain objective

it only needs to be one section of one wave to be sure...every other time is just like Yul Brynner...a repeat performance of the King and I (actually im more into analogyies than metaphores...suggests understanding and experience)

dont sow to many seeds to barren ground ....just in case i dont understand

But it's not a gradual increase but a sudden boost in the turn.

This may be a result of the equipment - don't confuse cause and effect.

Obviously you've never felt the wrinkles on your face smoothing out as the G-forces start to take effect midway through the turn - if you keep going you feel the shudder as your skeleton starts to dissemble - then you ease off the power and things return to normal - until you whack the foam and invert into the bottom turn...

Don't tell me you don't have wrinkles. Show me a kneeboarder without wrinkles and I'll either show you a bodyboarder or Matt N (sorry, the women are also all unwrinkled)

It's all elephants..all the way to the bottom (oops, wrong forum - that one's for the Flat Earth Society)

It's all about trade-offs. Different boards do different things. I think thrusters are capable of providing more sustained drive because cavitation effects (those HW provides as a benefit) are less in fins further apart

To quote Jimmy Hendrix before playing a song by Cream', "It's not that we think we're better than them, it's just that we think they're cool and want to do it our own way" (bugger - now I have to find the CD)

By the way, it's faster moving water around foil vs slow moving water, not low vs high pressure - the same effect that's used in water pressure (venturi) meters. It is sort of virtual low pressure, but you'll have to do the research

UNDENIABLE TRUTH # 1

a surfboard leaves its mark on the wave

UNDENIABLE TRUTH # 2

the wave dies on the shore

THEREFORE

all surfers are GUILTY!!


R.I.P. Johnny Cochran, we could use a creative defense here

but

the Honorable Red is presiding

and Headwax leads the defense

in the trial of Hart, McCray and Parks et al
vs
Mother Nature

mornin, good stuff,gets the brain loosened up..
Question...When talking of water movement around submerged moving objects-fins boat props.Are we possibly confusing cavitation with ventilation???
I do remember a conversation between two boat owners as to what was what-very heated-don't recall the outcome.
The answer is.......

But Willli


a wave dies on the beach surfer or no!


whose guilty then?


the creators are not on trial but the judgers

or as Tilopa said to Naropa in India many years ago

"Son, you are not bound by the perceived but by clinging ( to what you perceive) so cut you clinging Naropa"

or as parkes said to dorje many months ago

"careful of over analysis"

12345(fins) once i got a wave alive
...678910 then it died on the shore again


only to become the next set

its good you don't ride the A train

to quote a local philosopher

"Give me you wallet mutha f***er"

and obliging I lost my skegs

but my turn was quick

and my speed fantastic

for being on foot

[Bryan Jackson]

Unfortunately all of your discussions regarding the Bernoulli Principle and what provides lift are, for the most part, wrong!

I refer you to the following web site for an accurate and scientific depiction of the forces acting to provide lift in an airplane wing and thus, by way of analogy, a surfboard fin:

Air and water, flying fish maybe thats the next step

The 24th interesting statement quad v tri



[quote = headwax]


I'm not saying quads are better than tris. I'm saying that quads have surprising characteristics which should be explored.

[ quote = headwax]






your objectivity on all counts remains a pleasure headwax - the benefit of being an eyes man....looking through both



willli - to be sure - the big apple would eat me -

ps: thanks must go to Dr Strange for the continuing saga of this thread as his initial question back in Jan 04 got the ball rolling for the statements

(but does he have the key?)

is the door locked?

i get it now thats very clever!
I have admitted elswhere that i think quite slow

or as mick mallthouse (AFL coach) said in quoting someone else "the ox is slow but the earth is patient


i might make it to new york yet



I can always count on New Yorks finest!

[quadfin]

I think we need new classifications of "Quad" with so many variations of that species.

The Tris seem to be Aussie Tris or Traditional.

What I ride I consider a 2+2, with 2 trailers replacing the rear fin in an Aussie Tri config.

On the low pressure/high pressure, velocity, drag coeffcients, cavitation, angle differentials, etc....imagine you would could devote years just to one setup. Don't know how you could quantify other than performance. That is why I have stayed with one fin layout (with minor adjustments) for 15 plus years (right or wrong) and rotated surfboard design around that layout.
