Advanced concaves on 1970s equipment

Hey Stu, did you get the pics I sent through to you for this thread?

Thanks so much Stu, that's what I wanted to convey. For Udo, you can see the concaves, and I won't break down exactly where it transitions but basically it's a tiny bit of nose vee - going into a big single concave, going into double concaves - then the panel vee begins and the concaves continue running through the vee. Then it neatly fades out.

I like this type of bottom contour in pretty much any board I ride - more speed/sense of urgency than a simple panel vee, nicer meatier bottom turns as of the vee in the tail compared to a concave setup without.

Simba, this board has been dated about 1974 so before the Drifta. It's an excellent design.

And the point of the thread is to show concaves were very much refined well before the 1990s.

thanks once more Stu.

Yep, this board at Winki - can get a lot closer to kicking out at the valley than most. Something also should be said about how pinched the rails are going into the flyers - I think Fitz said to hold in high on a wave when it was critical - as you said. They do work.

It's a down the line speed machine, turning is of lesser priority, although it does so as big carves.
