Abstract
Abstract A fender apron protects the surface finish of a boat hull from dirt and damage from the actions of a boat fender in use. The apron is constructed of a flexible, resilient transparent plastic sheet. It is secured between the hull and the fender. It is adapted to move with and cling to the boat so that the fender moves against the outer surface of the apron.
