Grom board fin placement

Tom, I got two boards laying around that were used my boys about 5 years ago. 1. 5’4" squashtail (Rusty): Fins are placed, 3" and 10" (3" wide base fins) 2. 5’7" wing swallow (Tony Staples): Fins are placed 3 1/2" and 11" (4 1/2" wide base fins). Hope this helps out, Underground

Underground: Good stuff, just what I need to work up some numbers for this shape. Thanks!
