A surfboard having
- a core;
- a first elongate spring member located adjacent an upper side of the core;
- and
- a second elongate spring member located adjacent a lower side of the core;
- wherein the first elongate spring member extends substantially from a nose portion of the surfboard to a tail portion of the surfboard, and
- wherein each elongate spring member includes a plurality of layers of resilient material, and wherein a number of layers of resilient material is greater in a central portion of the elongate spring member compared to a portion of the elongate spring member towards the nose of the surfboard and compared to a portion of the elongate spring member towards the tail of the surfboard.

A method of manufacturing a surfboard, including the steps of
- shaping a foam core;
- forming a channel in a top surface of the foam core, the channel extending from a tail portion of the surfboard to a nose portion of the surfboard;
- inserting a first elongate spring member in the channel in the top surface of the foam core, such that the first elongate spring member is located adjacent the top surface of the core, wherein the first elongate spring member includes a plurality of layers of resilient material, and wherein the number of layers of resilient material is greater in a central portion of the elongate spring member compared to a portion of the elongate spring member towards the nose of the surfboard and compared to a portion of the elongate spring member towards the tail of the surfboard;
- and
- covering the foam core and the first elongate spring member with a shell layer.
