ABSTRACT:
A marine marker providing a service life, both of the structural rigidity as well as the surface finish that is presently unknown in the industry. The present invention utilizes the structural features of a high strength, readily formable plastic resin material in layers of high density polyethylene, nylon 6/6 and ethylene vinyl alcohol and employs a specialized manufacturing technique to provide a net shape of layered resin materials in the marker further enhancing its physical rigidity and serviceability. The invention further includes a protective surface unknown in marine markers with additional advantages to the application of the necessary informational messages on the marker, the addition of an ultra-violet protector and the providing of improved scuff-resistant outer surface.
