A blank 100 for a buoyant sports board, such as a surfboard, comprises a body structure 102 formed of a first material; and a core structure 104 formed of a second different material; wherein the core structure is embedded within the body structure and is a reticulate structure comprising a plurality of interconnected elongate members 106. The core structure preferably comprises multiple regions having different stiffness to provide varying torsional stiffness along the length of the board. The first material may comprise a foam material; the second material may comprise fibre-reinforced polymers. A method of producing a blank comprises inserting the core structure in a mould, introducing the first material into the mould and curing the first material to form a body structure in which the core is embedded. The core structure may be vacuum formed against a mould surface or may be additively manufactured. A method of producing a board may comprise cutting the blank into a desired shape and coating the cut blank. A core structure for a buoyant sports board blank and a buoyant sports board are further claimed.
