Hey guys is there a rule of thumb for "basic" canards positioning? Lets say I will shape a traditional fish, position the fins 7.5 inches from the tail, and wanna put some fcs1 plugs to try a twinzer for the first time. What positioning should I try and which fins should I buy? Thanks!!

More than one way to skin a cat
This may be a stupid questions, but why do you say there is more than one way to skin a case? I am assuming that the McTavish setup is different than yours. I hope that I don't sound to dense, but I find Twinzer fin placement fascinating. It sounds like there is no real tried and tested rules. Is there any where that I could get more technical discussions on Twinzers and how placement and channels affect the board?

Thank you

Yes.

The link below would be a good start:

I have ridden twinzers exclusively from the last 7 years. During my early exploration I experimented with fin size and placement to achieve a desired feel, this was the driver in to fin making. Ultimately I ended up making my own boards using shape3d to control all the variables. Some riders are quite particular to twinzers having Wil original placement (although the two Jobsons I measured showed me Wil's placement wasn't static) I'm a little more open minded and am driven by performance and feel more than what Wil did in the 90's

I also experimented traditional slots, channels and concaves. For me, even thou aesthetically I prefer the traditional Jobson slot out the tail I stopped doing them to simplify construction as I didn't feel enough of a difference to warrant the additional work required

Use a fusion plug cut in half for a stronger canard box.

Wouldn't the FCS fusion take up a lot more space? You are already close to the rail and the fin is small so I would think a regular FCS I plug would hold just fine. Also, the FCS I would weigh less and provide you with the ability to be more precise in the placement of the plug.

Thank you for the info. I love this stuff. I have been working on fin placement on twins with my shaper and I really like having my fins up a little further than a traditional fish, more like a twin plus trailer set up, with a bigger fin like the BMT. For me, the combo of the hold and speed without being tracky is perfect. The way we have it dialed in, the set-up literally feels just like a thruster, but faster. I want to experiment with a Twinzer fin to see if it will add a hair more drive for those mushy days and a little more hold for those hollow punchy days. I figure that I can always take out the Twinzer fin if I don't like it.

It also seems to me that a short little stubby fish would have the fins placed further back, where as a longer board with more rail line would work better being positioned a little further forward. But, I just don't know that much about fin placement yet. As I am getting older I am wanting to experiment and see what design differences can do for a board in various conditions. My shaper and I are pretty good friends and he is going to help teach me how to shape here in the near future if I can ever get the time. He is more than helpful in sharing his opinions, I just wanted to see what other people are experimenting with in other areas of the world. It is surprisingly hard to get detailed info on Twinzer design elements. I am honestly surprised that Twinzer aren't more popular.

@Bluehorn
imo you are on the right track. I set fins on a 6-2 old man HPSB at 6 3/4" I use a Griffin template scaled up to 5 3/8"H x 5 1/8"B this achieves a more drivey thruster like feel, only faster and without the need to pump as much for speed. On a my 6-5 at set at 7" and my 6-8 at 7 1/2"

Wil did a very small series of Twinzers called the "Hyperfenuvion". These were shorter, wider twinzer shapes designed to be used with elliptical fins. The Hyperfenuvion series twinzers were the only ones that had the fins set back. I think Ghosty, and Charles got to sample these designs. Maybe this is what you measured up and keep mentioning?
Who has those boards now??

It's was Charles' originally (@Dudebro's when I got a hold of it) I made my own version of it. Kind of a quad fishy outline, bevel rail, double concave nose to tail (iirc) I don't know if it came with those weird fin sets or not. I'd have to look but I think they were set @8 3/8" and closer to rail (than 1 5/8")
Not off much but @retodd 6-6 were set @8 5/8"
It would be great if @sk would offer some input from his extensive knowledge on the subject matter
