Yes, the Kona has more of a "hybrid" rockerline.
They plane with the nose significantly higher (relative to the water surface) than does a true longboard (with the moslty flat longboard rockerling).
The Kona gives up a bit of ultra light wind (< 7-8 knots) glide to the true longboards (Mistral Equipe,
Fanatic Ultracat, F2 Lightning, etc) for a bit better/earlier planing at >12-14 knots.
Let us know how your new found ideas work out.
I'll be interested to hear.
