Presently there is very little information or specifications to compare surfboards of similar size. To date no one has thought to measure and mark surfboards with a buoyancy or flotation rating. This invention seeks to improve the chances of a person buying a new surfboard to choose a board most suited to his or her weight and surfing ability. Currently surfboards are marked only with the length, width and thickness. The additional buoyancy rating would be very helpful when choosing or comparing surfboards. The process and testing equipment consist of a tank of water where the board is placed. A strap is attached to the board. A foot lever is used to submerge the board. A scale or force gauge is situated between the board and the lever to record pounds or kilogram of weight required to submerge the board. A permanent marking of the buoyancy recorded is fixed to the board.
