The Vetus WOA004A is a weld-on hull anode in aluminium-indium-zinc alloy (Mil-A-24779 SH), designed to protect steel hulls from galvanic corrosion. 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.

Streamlined for minimal drag, the WOA004A is welded directly to the hull via steel straps. Studs and bolts are available separately for fiberglass and wooden hull applications.

Key Features

  • Aluminium-indium-zinc alloy — Mil-A-24779 (SH) specification
  • Suitable for wood, GRP, aluminium, and steel hulls
  • Recommended for freshwater and brackish water use
  • Streamlined rectangular profile — minimal drag
  • Weld-on mounting via steel strap (included)
  • Replace when 50% sacrificed — inspect annually
  • Studs and through-hull bolts available separately
