King StarBoard® is trusted by professional boat builders, marine fabricators, and DIY boaters for applications including console panels, tackle center components, bait well lids, hatch covers, rod holders, leaning posts, and general marine hardware mounting boards. The 1/4-inch thickness is well-suited for lighter-duty panels, cabinet faces, and decorative or functional trim components where a thinner, manageable sheet is preferred.
As the original marine-grade polymer sheet with over 30 years of proven performance, King StarBoard® is the go-to replacement for marine plywood and teak, delivering a long-lasting, maintenance-free result on any watercraft.
