The singlefinned version, which rode well.
The first fin setup, with a very thin 12 inch base bulb tipped keel fin , and only 6 inches deep. The entire fin system was 16 inches long foreand aft. This combination resulted in one of the fastest boards I've ever ridden, a ridiculously fast section making rocket. Turns were easy and precise, but restricted to very long arcs. Shorter radius turns could be accomplished with a lot of effort, but were only required if paddlers got in the way.
Here's the second fin used for the MkII prototype, which was a great all round fin, many waves were ridden with this one in conjunction with the 6 inch tunnel and I was very happy with it.
MkIII sporting a new bulb tipped flex fin with carbon fibre upstand, which is still on the board today.
