When it comes to building or replacing wood, laminate or plastic accessories on boats, leading builders and OEM choose our Marine Lumber, aka Marine Starboard, because it lasts a lifetime. Our Marine Lumber is a UV-stabilized, marine-grade polymer sheet that provides excellent resistance to the sun and saltwater. Our Marine Lumber will not rot, delaminate, swell or splinter, and the matte texture requires no painting, finishing or maintenance. It can easily be cut, routed, shaped and drilled with standard woodworking tools. We compliment our Marine Lumber line with Lumber Lite – a cellular marine-grade utility sheet designed to withstand the harsh marine environment. Lumber Lite is 40 percent lighter than Marine Lumber – an ideal product for wood replacement or upholstery backing.
