ABSTRACT:
A fender having a compact spring shape for protecting an object, such as a dock or boat, includes a mounting portion connected to a resilient leaf spring portion. The leaf spring portion is designed to collapse and absorb a substantial amount of energy upon impact with another object while a free end of the leaf spring slides along a front side of the mounting portion. In a preferred embodiment, the leaf spring portion is extruded of a high-strength abrasion-resistant plastic material having a low coefficient of friction, such as ultra high molecular weight polyethylene (UHMWPE). The leaf spring portion may include multiple access holes sized admit a tool for installing or removing the fender.
