A method of making a surfboard comprising the steps of: a) forming a small panel for making the surfboard from one of ethylene vinyl acetate (EVA) and polyethylene (PE) foamable material; b) hot pressing the panel in a heating mold by placing the panel in a mold cavity having a surfboard shape and bounded by upper and lower mold portions and heating the panel to a temperature between 150°C-170°C for between 30 to 40 minutes to partially foam the foamable material of the panel. c) removing the partially foamed panel from the mold and allowing the panel to continue foaming and expanding until reaching a volume of between 6-10 times greater than an initial volume of the panel. d) placing the panel in a baking device and baking the panel at a temperature of between 150°C-200°C for between 10 and 30 minutes to complete the foaming of the panel. e) removing the panel from the baking device and placing the panel in a cooling mold at a temperature of between 30°C-60°C for between 10 and 30 minutes to cool and harden the panel into complete surfboard; and f) removing the complete surfboard from the cooling mold.
