Simmons-inspired mini-fish rocker?

can anyone share rocker dims on a 5’10" Simmons-ish hully twin fin? My dims are 5’10" x 20 x 23 x 19 x 16 (across tail block) and 3 thick.

Kirk,

Nose: 4 inches

Tail: 1 inch, to maximum 1 1/2 inches. (flatter for larger surf, and higher speed)

A board that size does not need much rocker to function properly.
