Will FCSII fins eject out of the system unintentionally when surfing?

The FCSII system has a high fin retaining force (around 12kg/26Ibs) and fins cannot be removed from the system by placing force on the front or side of the fin (i.e. the direction of forces applied to the fin during surfing). A fin can only be removed from the system by applying an upwards force to the rear of the fin.
