Manufactured to the highest material standard, it delivers reliable sacrificial protection in fresh, brackish, and saltwater environments — and is the preferred choice for freshwater use where aluminium's greater potential difference outperforms zinc.\u003c\/p\u003e\n\n\u003cp\u003eStreamlined for minimal drag, the WOA004A is welded directly to the hull via steel straps.
