I don't have the original fin yet, board shipped without it but they are on the way. As far as the fin position goes well I guess you would need to talk to Brian Szymanski about that. The fin in the photos is a fin I bought from John at G Board, but it felt way too big in the first try out, the board tracks very straight, completely different to The Pin which really seems to need the bigger than stock fin to allow you to paddle on one side for any distance.
Here is a picture of the fin I'm guessing will come with the board.
Interesting the whole fin position thing, this is a down-wind surfing board. You need to be able to turn the board without stepping back much at all, if the fin was further back I don't think you could do that.
The reality with a board like this is that surfing mainly consists of turning from straight down the wave to trimming across the face of the wave, you also need to be able to turn pretty quickly to change direction to pick up a swell coming from a different direction from the one you are already on. Very different requirements to a normal surf board. I've heard it described as always pointing the board "downhill", you constantly look to get the board to track into a lower piece of water than the one you are currently on. By focussing on that rather than trying to get the killer wave you will actually be going fast enough to catch that killer wave when it comes along and the average speed will be much faster. When you see someone really expert doing this it almost confounds belief, they seem to dart left and right on little swells you can hardly see, paddle less than you are and just blast past.
On down wind boards with rudders you can achieve this "darting" by constantly steering but a board like this needs to be super manoeuvrable but also feel stable when trimmed onto a bigger face. Pretty complex set of requirements to deal with for any shaper.
