Have been riding with asymmetrical fin positioning lately, with improved responce.  Thruster set-up converted to two fins, using much larger center fin, with a very small fin on the heal side.

I think using a more upright pivoting fin on the back side of a standard thruster  board setup with a more swept back fin on the front side would provide some Asym Assist.  Your thoughts?

You are correct.

Windigo Surfboard. This my newest ayso. Built for myself. 5'10" Toe side. 5'8" Heel side. Also one of my newest shapes the "Hitchcock" model. 22" x2 5/8".Did one of my "Faux" tint paint jobs over a play one the old Converse logo's airbrush.. Heel side has more tail rocker and Tri-Fin set-up. Toe side has a twin fin set-up.Thin tail. Single to double concave to a pretty hefty panel "vee" to put this thing on rail.  Will be surfing it soon! Barry

Hi,
Nice Board Barry, i like the way you have got more rocker on the heel side...
Been shaping another asymm board , outline much inspired by Southpaw and Will, I thought id try with a standard thruster setup but make the toe side rail straighter and add a little more rocker to the heel side. Had it shaped and then decided to insert a extra stringer through the line of the toe side fin to stiffen the heel side. It was a bit nerve racking cutting a perfectly good shape apart to insert the stringer, here it is so far...

I've been thinking about a simple asymm shape as per Noceans image just above. But I want to be able to surf it as a single fin as well as a thruster or quad so I may be restricted to symmetrical fin set ups. The board will also have a gentle roll bottom.


Folly or not ? Any advice for the fin setup (can I leave the single fin on centreline) ?

Hi, Cheers kiterider!

Yeah RDM, my thoughts would be if you want the single in the middle just do a similar outline to mine where to just straighten the outline one side as opposed to lenghtening it as some others have done. Lengthening the toe side rail would obviously lend some more drive on forehand bottom turns but just straightening it allows the pivot to be more central and I figured cut out a few variables and keep the fin setup symmetrical..., just my thoughts so far;)

heres an example of a board I found which is maybe close to what your thinking but the rail has been lengthened and the fin is off to one side, may be of help...

Inserted an extra bamboo stringer through the toe side fin line and asymmetrical deck patches:

here's one I have from a mate who is a collector, its PTs' board from the 81 Huntington Pro, which he won, yep on this board too ( so I have been told...pretty advanced for 81 I think... yet to ride it, but its been in the wagon about 15 times, just got so many other boards on the go, but its gettin a run real soon....

nice work Nocean...I did one similar about 90-91, it was rounded pin on one side and rounded square on the other, thruster and everything was symmetrical until approx the last 18"....did 2 of them almost identical, and the first one was the best, or maybe I was just trying to make the 2nd one go like the 1st....it was very different to what everyone else was riding back then thats for sure....

I've been thinking a bit about all of this recently and finally did something about it on the weekend.


I surfed my round tailed stubbie in head high beachbreaks with a heel and centre fins at standard thruster locations (90mm and 290mm up from the tail respectively) and a larger toe side fin (134mm high) set at 150mm up from the tail.


I was expecting that with such a disparity between the fin locations that something weird was definitely going to happen. But it felt fine - faster and a little looser than the standard thruster set up it seemed.


I surf the same board with all sorts of fin configurations (single, twin thruster and quad) so I'm used to adjusting to the different "feels" - maybe that helped me. And I'm not what you would classify as a "performance" surfer so I probably don't push surfboards anywhere near to the limit of their designs. But I'm still suprised that the issues I might have expected didn't raise their heads at all. Maybe my surfing is that bad that it doesn't matter what's underneath?


I need to surf it in bigger waves and at higher speeds to confirm what I felt and to expose any issues, but at this stage I can't yet discount that such a set up is without merit.


I will report back again after the next surf.
