7'0 Mid length fin placement, Single and Quad

General Discussion
1

I’ve been really interested in the Chris Christensen C-Bucket.  So decided to skin an old longboard and shape one myself.  7’0 x 16 x 21 1/4 x 14 x 2 5/8.  It’s a slight hull up front, to flat, to single concave out the back. 

I am planning on putting a single box in it as well as a quad set up so I can run it either way.  However, I don’t know where to put the fins.   How far forward should a single box be on a mid length?   What is proper placement for a quad set up?

Thanks for the knowledge!

Single fin 4"-6" from tail. Quads rears 5-8" from tail quad fronts 10-12" from tail. Or check out McKee setup.

I usually put the back of my box close to where a thruster fin would go. Then you have the option of single, quad , or thruster. For Quad placement I always go with the Bruce McKee system.
