McTavish Quad Fin Placement -- Doh.

Match them to foot width.  Drift magazine article. Slater reference.  Dang.  Funny how (to me) surfboards keep having to evolve toward working with the dimensions of the body riding it, rather than being designed that way from the get-go.

almost all boards and fin configerations benifit the most when your fins are directly under your rear foot. on my quads i have always rolled with your heel on your rear fin and your toes on your front fin… thats why design of a quad boards tail and fin placement is so critical to each person. the thruster just averaged out those placements so that the one setup will work with a wider variety of surfers & conditions. i have always asked and used the surfers old board as a guide to where thier feet are most on the tail. this has helped me determine the fin positions when making a new custom for them.
i would of thought this was common practice for shaper/designers?

sweet jesus,

i thought mckee was australian? why did he not mention him? he OBVIOUSLY put the fins OFF the rails.

damnsee

are they for real      paten this ha’’    i dont there the only ones that ever looked at foot placement’’

**more goblegook from the spinmaster   when will it ever end?

Now, I just got an idea: why not put just ONE fin that would be centered right on the stringer so that your heel and toes would have the most leverage each side?

I think I’m on to something…

I might call that a “single fin”.

Sorry Balsa old mate

Already got a patent going on that but I call it the MONOFIN.

As in all cutting edge design placement is critical.

Once again sorry to burst your bubble

Cheers

I’m gonna patent Aussie-style shit-talking.  You all are gonna be into me for a heap of dough.  And no I WON’T take that VEGEMITE shite.  

Nobody ever thought of glueing a flip-flop to the tail.

Let’s call that footstraptailpad and put a bunch of fins underneath…

Munch munch, good food for thought Jankrow, thanks

BTW, I’m supposed to meet Bob Mc Tavish tomorrow at Pukas’ in spain (he’s here on a european tour with Steve Walden and a few others). I’ll try and talk about that with him if I can.

now you're just trying to make us all jealous Balsa... ha!

 

Well, er…, yes!

 

And, yes, you may be jealous because I had the privilege to talk with Bob for something like half an hour about many things. This interview about the shorter span between side fins, of course (he seemed surprised that I had read it, asked me where, and I said “Swaylock’s”) but also Nat Young coming to Guéthary in 1968 with his first “short boards”… He asked me lots of questions about my work and seemed sincerely interested in it. I had a great time and I hope that Bob will drop by my shop in the next few days. I also got to talk with Steve Walden (who took this photo, BTW, thanks Steve!) and Thomas Meyerhoffer. Not a bad day…

more goblegook from the spinmaster when will it ever end?

 

Straight over their heads Huie!

 

Started in November 1967 - still going strong - couldn’t have done it without Eric Blum, Surfer Magazine and then Surfer’s Journal!

 

The lame surf journos who swallowed it hook line and sinker have faded from the scene, but their nonsense is now being regurgitated as legitimate history.

 

Funny as…

ah midget     oh so true

Poisinous dwarf?

I  like the concept, but it’s definately something you couldn’t claim as “your own”

Huie…       Have you tried this idea, and what are your findings…?

If I were building the same popular  lenght / outline / rocker etc., I’d make it my duty to adjust the fin box locations to find what worked best for the riders weight / footsize, and ability., if for nothing more than my own curiosity , and peace of mind…

That’s what “custom” means to me, anyway…

A board builder friend recently said to me  ::   " Don’t knock it, 'till you try it " … A humbling shock to the system, I must say…
