I’m no pro on fin placement.
But IMO the Moonstone is a swallowtail.
(Placement of keel fins for a “Fish” is more specific.)
I have seen a wide range of recommendations for twin fin placement.
Seems like board length is a factor also.
Starting first with this old Sways thread;

Twin fin - fin placement

Hey all, I have shaped a number of single fins and 2 +1 boards so far but no twinnies. I was wondering if anyone had any idea of where to place fins on twins or the angle to set them. Also is the principle of moving the fin up the board for more snappy turns and closer to the tail for longer drawn out arcs the same? I’m shaping a pintail single winged board to be a twin at the moment. Thanks in advance for advice, Felix [image]
