I'd love to know how this board was riding...
I suppose you've tried it already? Any comments?
If you're talking about my rail fin concept, it works a treat. A real treat. Its really designed for flat water and tons of power but I've had it out in gust of 20/23mph on my pl g18 in mad chop and it just holds an edge like glue. I'm a few revisions on from that board. Currently a 122 with rail fins on one side and a normal side cut modelled after a jimmy on the other, the bindings can be switched around
Lots of fun, a little too much concave makes the board a little too skatey but I think I'm going to sort that with bindings instead of straps.
Again, probably best suited to flater water but the concave suits the chop at the same time. the rail fin starts acting like a foil above a certain speed and it feels like your riding a knife through the water.. AWESOME feeling but probably not everyone's cup of tea. 122 is probably a little too short as the board really twitches if you put both fins in the water while travelling.
