1. A pivotal surfboard fin assembly for use with a surfboard, the assembly comprising: an insert bracket mountable to the surfboard and defining a board face and an opposing bracket face, the insert bracket having a lock pin aperture and a flex pin cavity each extending from the bracket face toward the board face;an elastomeric flex plug disposed within the flex plug cavity, the flex plug having a flex plug hole formed therein;a surfboard fin pivotally connected to the insert bracket and having a fixed lock pin configured to be insertable within the lock pin aperture, and a flex pin disposable within the flex plug hole; anda compression element coupled to the insert bracket and configured to compress the elastomeric flex plug to control pivotal movement of the surfboard fin relative to the insert bracket. 2. The assembly recited in claim 1, wherein the compression element is configured to selectively compress the elastomeric flex plug to allow for selective control of the pivotal movement of the surfboard fin relative to the insert bracket. 3. The assembly recited in claim 1, further comprising an adjustment element coupled to the compression element to control compression of the elastomeric flex plug. 4. The assembly recited in claim 3, wherein: the compression element includes a compression pin translatable relative to the insert bracket and the flex plug to compress the flex plug and;the adjustment element includes a thumbwheel coupled to the compression pin, wherein rotation of the thumbwheel relative to the compression pin effectuates translation of the compression pin relative to the flex plug. 5. The assembly recited in claim 1, wherein the compression element includes a first compression pin having a first compression pin first end engaged with the insert bracket and a first compression pin second end sized and configured to compress the elastomeric flex plug. 6. The assembly recited in claim 5, wherein the compression element includes a second compression pin having a second compression pin first end engaged with the insert bracket and a second compression pin second end sized and configured to compress the elastomeric flex plug, wherein the first and second compression pins compress the flex plug in opposing directions. 7. The assembly recited in claim 1, wherein the flex plug is fabricated from a rubber material. 8. The assembly recited in claim 1, wherein the flex plug is cylindrical. 9. A pivotal surfboard fin assembly for use with a surfboard, the assembly comprising: an insert bracket mountable to the surfboard;a surfboard fin pivotally connected to the insert bracket; andan adjustable pivotal restriction element coupled to the insert bracket and configured to allow selective adjustment of the pivotal movement of the surfboard fin relative to the insert bracket; wherein the adjustable pivotal restriction element includes an elastomeric flex plug connected to the surfboard in and a compression element configured to selectively compress the elastomeric flex plug to allow for selective control of the pivotal movement of the surfboard fin relative to the insert bracket. 10. The assembly recited in claim 9, further comprising an adjustment element coupled to the compression element to control compression of the elastomeric flex plug. 11. The assembly recited in claim 10, wherein: the compression element includes a compression pin translatable relative to the insert bracket and the flex plug to compress the flex plug; andthe adjustment element includes a thumbwheel coupled to the compression pin, wherein rotation of the thumbwheel relative to the compression pin effectuates translation of the compression pin relative to the flex plug. 12. The assembly recited in claim 9, wherein the compression element includes a first compression pin having a first compression pin first end engaged with the insert bracket and a first compression pin second end sized and configured to compress the elastomeric flex plug. 13. The assembly recited in claim 12, wherein the compression element includes a second compression pin having a second compression pin first end engaged with the insert bracket and a second compression pin second end sized and configured to compress the elastomeric flex plug, wherein the first and second compression pins compress the flex plug in opposing directions. 14. The assembly recited in claim 9, where in the flex plug includes a flex plug hole formed therein, and the surfboard fin includes a flex pin disposable within the flex plug hole. 15. The assembly recited in claim 9, wherein the flex plug is fabricated from a rubber material. 16. The assembly recited in claim 9, wherein the flex plug is cylindrical.
