Hi, I am currently working on designing a single fin for really fast hollow hurricane surf, essentially being built for getting barreled. I am not that big weighing in at 5’9" and 145 lbs. after a large meal. I am able to hold my own in longboarding contests and I can do allright on my sub 6’ fishes too. Mainly I am just having trouble deciding where to put the wide point on the board. So far I have come up with making a 6’ rounded pin. I was thinking the width should be around 20 to 22 inches and the tail to be pretty thick and wide also. I am not really sure what to do about rocker either. I don’t tend to put lots of rocker in my boards but I have always heard that rocker was good for barrels. For rails, starting from the back and going up a third of the way i was going to make them rolled and then i was going to round them off for the rest of the board. I was thinking wide point about 2-3 inches forward from center but I don’t know if that would be good or not, as I tend not to surf hard on either foot but shift them around alot (longboarding background I guess). Any ways, any help would be greatly appreciated.
Many thanks

P.S. I was thinking about making the board 2-2.5 inches thick for early entry(?) into the wave. I guess it would essentially be a single fin semi-gun.
