My 6’11" x 22" x 3" double wing round pin( I weigh 215+lbs), I moved the thruster fins up to 13 1/8 and 1 5/16 from the wider winged portion of the rail, and mckee(ish) quads locations about 6 1/8" , both in line with the wings. I was always more front footed and would have my back foot infront of the fins on previous boards, so decided to move the fins up closer to my backfoot, but kind of regret it now and would likely choose 12.5 with the probox 1/4 inch fore or aft adjustment, if i were to do it over.
I can’t say much about the Mckee quads as I have yet to click with it as a quad. I use proboxes and pretty much always prefer them all the way back. While I don’t like traction pads in general, i recently installed one only over my rail fins with no arch bar or tail kick near back fin, just so I know without looking or moving my foot, if it is in the right spot or not on pop up. I find frontside I am usually placing my back foot forward of it, and backside it falls right on the pad,or behind it
Next fins I make, are having the tabs moved forward on the fin so it can sit further back in the board, but these are much higher aspect ratio fins than the norm, and these should be further back.
So I think proper placement is kind of determined by how your client surfs, though I would say not to go past 12.5 for the fronts, as bringing the fins closer to where my foot naturally falls frontside, does not feel quite right.
Not sure of toe in in terms of 1/8 or 1/4", I use a straight edge and the inside flats all point to a spot ~23 inches in front of the tip of the nose.
Not exactly the same thing but I can check where I put the fins on my 7-2 bat tail. I’ll do that today. I looked in the archives and couldn’t find anything posted from when I built it.
rears are approx. 5 1/8" up from the corner of the tail to the trailing edge of the fin itself, 1 3/4" in from the rail, fronts are 11" up to the trailing edge, 1" in from the rail
Looks great, I would probably enjoy riding this. Looking forward to the glassing shots, hoping you keep em coming!
I didn’t mention cropping cuz for me its just an aesthetic thing, the screen grab takes in the extraneous periphery, but I can post them unedited. But yes, I do follow the screen grab with cropping before posting.
