1. A fin module for attaching a fin to a surfboard comprising a top deck, a core, an underside, and a bore extending through the core between the top deck and the underside, the fin module including: a fin comprising an inner core integral with and including an extending base portion made of substantially rigid material and a cover forming a fin blade made of substantially resilient material, the substantially rigid material having a hardness greater than a hardness of the remainder of the fin; anda fin box made of a substantially rigid material and having a cavity for receiving the base portion; wherein:the fin box is formed separately to the fin and adapted to receive interchangeable fins having a similarly extending base portion construction;the fin box is adapted to engageably receive an engagement end of a connector having a head anchorable at or near the deck and an elongate member extendable through the surfboard core, the connector operable to pull the fin box toward the connector head to adjustably space the connector head from the fin box;the fin box is engageable to a separate extending base portion of an interchangeable fin for attachment to the surfboard; andwherein the fin base is engageable to a separate fin box for attachment to the surfboard. 2. The fin module according to claim 1, wherein the inner core is a reinforcing center that comprises three bars joined in a triangle. 3. The fin module according to claim 2, wherein the bars are thick in elevation and thin in plan view. 4. The fin module according to claim 3, wherein the apex of the reinforcing center extends to about half the distance of the fin apex in use from the underside of the surfboard. 5. The fin module according to claim 4, wherein a multiplicity of fin units corresponding to the fin are alternatively combined with the fin box and are provided in the form of a modular kit. 6. A fin module for attaching a fin to a surfboard comprising a top deck, a core, an underside, and a bore extending through the core between the top deck and the underside, the fin module including: a fin comprising an inner core integral with and including an extending base portion made of substantially rigid material and a cover forming a fin blade made of substantially resilient material; anda fin box made of a substantially rigid material and having a cavity for receiving the base portion;wherein the fin box is formed separately to the fin and adapted to receive interchangeable fins having a similarly extending base portion construction;the fin box is adapted to engageably receive an engagement end of a connector having a head anchorable at or near the deck and an elongate member extendable through the surfboard core, the connector operable to pull the fin box toward the connector head to adjustably space the connector head from the fin box;the fin box is engageable to an extending base portion of an interchangeable fin for attachment to the surfboard;a boss to receive the connector engagement end, wherein the boss is configured to receive an insert, the connector engagement end being engageable within the insert portion in the boss;the insert is in the form of a plug forming an internal lining within the boss, the insert made from a softer and/or more resilient material than the fin box and the connector; andthe insert frictionally engages the engagement end to prevent inadvertent loosening of the connector relative to the fin box. 7. The fin module according to claim 6, wherein the insert is internally threaded, the engagement end forming part of a threaded bolt adapted to secure the fin to a surfboard. 8. A fin module for attaching a fin to a surfboard comprising a top deck, a core, an underside, and a bore extending through the core between the top deck and the underside, the fin module including: a fin comprising a core and an extending base portion made of substantially rigid material and a cover forming a fin blade made of substantially resilient material; anda fin box made of a substantially rigid material and having a cavity for receiving the base portion; wherein:the fin box is formed separately to the fin and adapted to receive interchangeable fins having a similarly extending base portion construction;the fin box is adapted to engageably receive an engagement end of a connector having a head anchorable at or near the deck and an elongate member extendable through the surfboard core, the connector operable to pull the fin box toward the connector head to adjustably space the connector head from the fin box; andthe fin module is configured to attach more than one fin to the surfboard. 9. The fin module according to claim 8, wherein the core and the base are formed in two separable parts, a fin with a fixing base or tab and a separate fin box. 10. The fin module according to claim 8, further including a boss to receive the connector engagement end. 11. The fin module according to claim 10, wherein the boss is configured to receive an insert, the connector engagement end being engageable within the insert portion in the boss. 12. The fin module according to claim 11, wherein the insert is in the form of a plug forming an internal lining within the boss, the insert made from a softer and/or more resilient material than the fin box and the connector. 13. The fin module according to claim 10, wherein the boss defines a chamber that is substantially cylindrical and includes an internal wall feature that cooperates with a complementary insert feature to prevent rotation of the insert in the boss. 14. The fin module according to claim 13, wherein the insert is separable from the boss chamber and replaceable. 15. The fin module according to claim 8, wherein the fin box includes more than one cavity to receive a plurality of fins. 16. The fin module according to claim 8, wherein more than one fin module may be used on a particular surfboard, to provide a twin, triple or quad fin arrangement. 17. The fin module according to claim 8, wherein the cavity defines a horizontal engaging surface in the fin box. 18. The fin module according to claim 8, wherein the cavity is a central, longitudinally aligned cavity in the form of a channel shaped slot and the fin base portion includes a corresponding mounting edge. 19. A fin module for attaching a fin to a surfboard comprising a top deck, an underside, and a bore extending through a core between the top deck and the underside, the fin module including: a fin comprising an inner core and an extending base portion made of substantially rigid material and a cover forming a fin blade made of substantially resilient material; anda fin box made of a substantially rigid material and having a cavity for receiving the base portion; wherein:the fin box is formed separately to the fin and adapted to receive interchangeable fins having a similarly extending base portion construction;the fin box is adapted to engageably receive an engagement end of a connector having a head anchorable at or near the deck and an elongate member extendable through the surfboard core, the connector operable to pull the fin box toward the connector head to adjustably space the connector head from the fin box; andthe fin box has an outer chamfered edge.
