Abstract: A flexible surfboard is provided in an embodiment. The surfboard includes a foam body having a length, width, and thickness. The surfboard includes a flexible structural component tapered in at least one dimension, and disposed within the foam body. The flexible structural component has as dimensions a length, width, and thickness, and is configured to flex under induced forces during use. The flex characteristics of the flexible surfboard are primarily dependent on flex characteristics of the flexible structural component. The tapered flexible structural component is oriented within the foam body such that the length, width, and thickness of the tapered flexible structural component align with the length, width, and thickness of the foam body, respectively. The thickness of the soft body is less than the width of the soft body, and the width of the soft body is less than the length of the soft body.

Abstract: The present invention is a variable-rocker surfboard, comprising: a tapered composite panel enveloped partially or entirely in a soft foam. The tapered composite panel is oriented horizontally partially or entirely within the soft foam, such that the length, width, and thickness of the panel correspond with the length, width, and thickness of the soft foam. The objective of this design is to provide a surfboard with desirable flex characteristics that result in variable rocker, wherein the tapered composite core attributes the flex characteristics, and the soft foam provides volume for the desired buoyancy. The present invention may be provided as a surfboard blank, wherein the soft foam needs to be worked into a surfboard shape. The present invention, may also be provided as a surfboard, wherein the soft foam has been shaped to the desired design and may be laminated with an exterior skin.
