Surfboard and blank for a surfboard

A surfboard constructed using a surfboard blank, the surfboard blank comprising:

• a central portion extending from a nose to a tail end of the surfboard blank wherein the central portion comprises a stringer with one or more central panels;
• rail panels attached on either lateral side of the central portion such that the central portion is flanked by said rail panels, wherein the rail panels generally extend along a longitudinal axis of the surfboard blank;
• wherein said central panels are formed from a first resilient foam core material and the rail panels are formed from a second resilient foam core material, whereby the first resilient foam core material has greater buoyancy in water relative to the second resilient foam core material, and wherein a coating is applied to the surfboard blank to provide the surfboard with resistant properties.
