Cabell/Morgan/Lynch Keelfin in a smallwaveboard?

General Discussion

I've been toying with the idea of making a board with a single widebased keelfin for milking softwaves or rely fast tiny zippers. The above mentioned boards Nat and Wayne surfed needed big powerfull waves to work, so why am I considering using the fin in the small waves. Well defining work in this cas would probably mean that the narrow 7-8ft pintails tended to track in smaller or weaker waves, but If you are only after pure speed and drive down the line and minimum amount of drag I think these fins could be hard to beat.

Instead of the narrow gunny outline, I would use a widetailed veloesque outline around 8ft, with hint of roll in the entry otherwise a pretty flat bottom, with low rails.Will probably track like hell, but why stick to keels on the rails if you are mostly surfing the board flat and almost never on rail in tiny or fat waves. This board would be for days when I would not be able to catch or make the waves with my 9'5 fishsimmons. No turns jsut get in if you can and run like hell, speed frills..

Tons of drive and minimum amount of drag, right? Almost like a finless board or alaia..

You might be able to try the idea out first by running 2 fins in tandem on an existing board, like 3" in front of a 7" with a wide base like a 4A.  

I guess a couple of the finless guys are using the little bonzer runners, like 2" tall, at the rear corners in conjunction with their channels.   I forget who was doing it but the runners added enough hold that they ended up putting a cutout at the corner to loosen the board up for better turning.
