Tandem Wherry skeg

I'm building the TW, and this evening filleted my previously attached skeg. As I'm looking at it, I'm wondering if the front of the skeg should be feathered down to a point, or should there be the flat expanse of the bottom and then all of the sudden, the 1/2" front of the skeg jutting up out of the bottom? The instructions don't mention anything. 

I would probably taper it or round it off a bit so if you ran into anything it wouldn't grind to a halt. You would think there would also be less turbulence / drag with it rounded off.
