Thanks Tiesda for your answer on this. It confirmed what I was thinking and readily eliminates any misunderstanding.
I'm still a bit curious though about the added small fin at the rear of the board. I'm thinking that it tightens up the straight line tracking of the board, particularly to windward, but I was wondering whether its addition makes the tacking or jibing a bit more technical? Also, is there a chance that a view of the small fin will be added somewhere on the Starboard website?
Thinking back on the video that Remi posted on the forum a few months back, I remember that the board included a small fin at the tail of the board. Seems fairly clear now that the board was very likely a prototype for the 2009 model.
