A method is described for inhibiting marine fouling on a surface. The surface is contacted with a composition comprising a waterborne polyurethane that is crosslinked with an acrylic acid functionalized polysaccharide, water, and a preservative. The composition is then dried to form a deposited film. The polysaccharide may be xanthan.
