Does anybody have a proven fin placement for a 7’4" round pin tri fin(11x19.5x14x2.75)Nothing fancy on the bottom, flat to slight spiral vee through the fins. Purpose of the board is big wave semi-gun. Thanks - Skip
A lot depends on the rocker. Safe is 12 to 12 1\4 side fins and 3 5\8 to 3 3\4 rear TW
