OK fast? reduced wetted area, right cutouts (oh we're ignoring fins here BTW), flat rockered.
What else makes it fast? Not much on that list....?

Now I have a fast slalom but without affecting top end speed too much, what to make it turn?
Smaller cutouts to help plane thru gybes......what else? (don't want to play with rails too much and slow it down)


Now to make it more comfy and easier to ride fast in chop? We still want a slalom board,not heading to freeride...
Little bit more vee, little bit double concave.
What else?
