The present invention relates to a resiliently flexible fin for a surfboard or another surface watercraft, the resiliently flexible fin comprising a titanium or titanium alloy core and an opening in the trailing edge that enables a portion of the rear of the fin to resiliently flex against the force of water as the surfboard is turned, which can generate additional forward thrust for the surfboard as the surfboard exits the turn and the fin returns to its unflexed state displacing water in its path with force.
