Rocker curves — Remain engrained to the original proven curves.
Outline curves — Both nose and tail were usually the same width at 12” and remain true, but with more precision, including added curve and width around 6” from the tail. One “secret” about the original’s success was that, unlike most all other “fish” the tail width on ours was closer to that of a typical HP Shortboard. This allows much more control off the tail than typical fish designs.
Bottom Contours — The classic single concave to double concave, accelerating vee combination are defining design elements and hold true to adherence.
The Thickness Flow, Deckline, Rails, and Tail Foil — They were all over the map in those rudimentary hand shape days. Each board was different, with most of them having noticeably different curves and thickness from one rail to the other.
