Silicone-based paints can provide more environmentally friendly protection, at least for some hulls—although at a much higher price than copper. These products theoretically make a boat’s underside too slippery for fouling organisms to hang on once the vessel gets underway. If your boat does 20 knots and you spend plenty of time on the water,
silicone-based paints could be a definite possibility. “The faster you move,” says John Ludgate, vice president of sales and marketing at Pettit, “the faster the growth gets removed from the bottom of the hull.” With any nonstick paint, if you seldom leave the dock, you’ll have to scrub your hull regularly. According to Ludgate, most nonsticks must be wiped down weekly. Coatings based on silicone shouldn’t be confused with ablative bottom paints, which operate on a different principle. The surface of these paints wears away slowly like a bar of soap, each time exposing more copper or other biocide

Veridian is a biocide-free easy clean coating for propellers, out-boards, outdrives and stern-gear. It has an ultra-smooth, non-stick surface which can be cleaned quickly & easily with a sponge or soft cloth to maintain a bright, clean finish. No need for time-consuming abrading or high pressure water-washing to remove fouling during the season!

Unlike many coatings, Veridian adheres strongly to aluminium propellers & stern-gear substrates after suitable surface preparation and priming (where necessary). Even substrates with a previous antifouling coating still present (except VC®) can be overcoated providing the system is in good condition & well adhered. Not suitable for bronze or stainless steel. This product contains no biocides.
