A hull protected against osmosis

For the underwater parts and more generally, composite exposed to seawater, the use of vinylester resin, especially epoxy, is a guarantee against ageing of the composite. Vinylester resin is much more resistant to moisture ingress than polyester resin and eliminates any risk of osmosis when used properly. Epoxy resin has even better properties. Aureus XV yachts are therefore fully protected against any risk of osmosis.
