Any advice would be great thanks~
Couple of charts around the place are specific to rounded square tails - are fins on a round tail generally a bit further forward from the end of a round tails because they are not “squashed”?
I would be keen for a bit of pivot with the fin layout if possible

Are you truly going to be using this board as a “Gun”? For use in larger waves? Eight foot plus? Because if your intent is so; You would be better off to “Quad” that board. Or at least set it up with an 8 or 10” center box and fin boxes for a Quad. When I set a board up like that I use FCS Fusion boxes because they are lighter in weight. As I recommended on a thread for placement on a 7’0; 5, 5 1/2” or 6” off the tail. A long box will give you forward adjustment. Quad fins off the rail or McKee setup. You can ride it either way or as a Five. AS a five use the “Rail” setup for Quad placement. Then use a FCS Adapter in the center box with a Fifth fin of your choice.
Hi OSS1 thanks for your reply, yes big wave set up only, 8ft+ and I should have said I was looking at a quad/thruster set up yes. I didn’t consider doing the centre fin as a single but now that you mention it that does sound pretty cool.
The MCKEE quad placement (F13 15/16” R 6 13/16”) but the American Surf Industries table is front: 16 1/4” - that seems like a huge variance between 13 15/16 and over 16”??
Can you link me anything about what off the rail versus McKee means?
Is that setting the distance of the fin dot from the rail compared to measuring their placement from the stringer?
Cheers

There is info here at Sways in the Archives. Search Robin Mair. He is a proponent of an “on the rail set up”. From the rail.

Mckee quad set up is fine for gun. In big waves that’s back rail the more important. You want it lock in wave, quad help for that, also need small fins and low cant because you don’t want lift from fins, only keep rail loocked. On the rail back fin quad work for that but some guys (heavier in general) don’t like the lower drive feeling at take off when board is flat.
For gun i set back fins with no toe-in and no cant, back somewhere between 1.75" to 2" from rail.
