This is all amazing to me after posting these 2 articles .
It seems that none want know this history of this term and yes it became used for double concaves after its origin by Bob .
Bob started using concaves shortly after .
Inter Island Brewer’s had slight Roll tappering to Vee like a Spiral - no concaves .
Wish you were there :-)
Hi Mike.
I think all human beings are visual learners (unless you are vision impared of course) as it’s the way we were designed/evolved (but let’s not get into that discussion right now). But we are capable of so much more than that.
I agree that a picture is much more efficient in the process of the explanation of some ideas, but I think that in the process of that we miss the opportunity to actually think as deeply about the idea as when you try to describe it.
Maybe I’m a bit twisted, but I actually enjoy trying to decipher the ideas hinted at on here by those with a lifetime of experience on the subject. Supposedly the written word is one of the things not hard wired into the human brain, even though verbal language is. Arguably mankind’s greatest achievement, despite the amount of shit that has been written since it’s invention. But that’s more of an application issue than anything else.
And of course you (and all of us) are well within our rights to ignore, speak or double speak as we see fit. Although ideally I’d pefer the double speak to be left to those who have pearls to share. I don’t mind if the answers don’t come easy. That’s half the fun.
Cheers

Take it easy on us Greg. We’re still trying to define what it actually is. We’ll get to the history of the original term once we get past that.
Unless of course the history of the original term actually explains what it is. If that’s the case, then fire away and tell us more of the history.
Looks like a girl I used to know. Not her pelvis, but her diaphragm.
I own a 9’ Brewer Gun and have seen Brewer describe the bottom contours of a standard Brewer Gun. And I don"t remember Brewer using the term “spiral” At All.
Thank God for Bob Cooper, Dennis Ryder and Tom Hale. Because they took Mctavish’s rather crude and ineffective design, refined it, redesigned it ETC. and made it into something that is the basis for everything we shape today, Lowel
That means he didn’t in 1969-70 either :-)
You selectivly ignore most of what I say here , very similar to Surfermag posters .
I don’t need more of you .
See ya
Forgive me.
Just really pissed in general about the negativity generally dished out upon schedule by certain “stoke sucking fools”.
Meant no real malice just sayin’ which is kinda BS.
Greg no crap here!
You are among a select few that have earned respect.
Also I can back it up, by simply saying what you profess has been proven to me your designs are very functional and more.
Enough brown nosing.
IF your attention is drawn in.
I would love to know you option on single concaves…
PM me if you like but…
I “needs to know” cuz I am old, once again building and really don’t have time for BS.
Aloha.
Thanks Zourite! Mike
Jeez, Greg. Are you here to try to ruin Swaylocks with your negativity like you did surfermag?
Ive never heard the original vee-bottom described as a spiral vee ?..not in Australia , anyway…Ive always regarded a spiral vee to have the vee apex , in front of the fin , and the rail line accelerating gradually above the stringer line @centre , creating a spiral in the bottom contour , from the apex of the vee , and out through the tail ?..early ones were convex , not concave…they were often used in conjuction with multi-flyer tails , and could pull amazingly short arcs…and they were , in fact , a true spiral… I think “spiral vee” is a term commonly misused .
That is so very true. Same can be said about your other comments, in the above post. (very true)
“Ive never heard the original vee-bottom described as a spiral vee ?”
I posted an interview with Bob a few years ago here were he says Spiral Vee in describing his original design …
The Brewer article I posted has RB saying he uses Bob’s Spiral Vee in all his boards at that time .
Bob McTavish showed me how to make a spiral vee. I’ve used it ever since. Read more at - See more at: http://www.swaylocks.com/node/64445#sthash.MvFS4e0M.dpuf
This was 45 years ago which explains why Mc ding did not hear RB say anything about Spiral anything in his current Brewer shape. 
Fits the Spiral description - wide arc at center narrowing at center at tail
Midget was my favorite of all surfers in Oz at this time .
What year is this pic ?
Winter 67 , I think Greg…not certain though.
Wind and sea Longreef contest was in November 1967 , I was there in December .
…well you may find this an interesting read…http://www.surfresearch.com.au/1968_Farrelly_Design_Interview_Surf_Int_V1n3.html
Gordon Woods had a 7-11 model , stringerless , step deck when I was there .
Things changed monthly :-)
The 7’-11" sounds like a Foley board , or a product of the extreme length reductions…most things went over my head when these things took place …I was 13 , and wouldn’t have known if my arse was on fire…(lol)
