A anti-fouling composition comprising: - a cured or cross-linked polymer free of perfluoropolyether moieties, and - a fluid fluorinated alkyl- or alkoxy-containing polymer or oligomer. Preferably, the fluorinated alkyl- or alkoxy-containing polymer or oligomer comprises a repeating unit of the general formula: -{[CFR-(CFR)m-(O)n]p-[CFR-O]q]}- wherein: n is 0 or 1, m is an integer from 0 to 4, R independently is H, F, CI, Br, or CF3, and the ratio q/p is 0 - 10, and the fluorine-free polymer is an organosiloxane-containing polymer comprising a repeating unit of the general structure -[SiR1R2-O]-, wherein: R1 and R2 are independently selected from hydrogen, alkyl, aryl, aralkyl, and a vinyl group. Also disclosed is a method for inhibiting fouling of a substrate in an aquatic environment by applying the anti-fouling composition disclosed.
