1. Choose your material:
- Zinc for saltwater boats
- Aluminium for saltwater or brackish waters
- Magnesium for fresh water
2. Select Style and Model:
- Bolt-on hull anodes come with 8" or 9" hole centres (You have to buy the studs or bolts separately) weld-on requires the anode to be welded in place (usually commercial vessels)
- There are different models of anode depending on where you put it. Shaft and beneteau anodes protect the drive shaft and stern tube. Hull anodes can be placed anywhere depending on where you want to protect and pencil/engine anodes tend to be specially designed for each brand and model engine. Button or disc anodes are designed to protect rudder / trim tabs.
*For more information on placement or engine anodes please contact us on 00353 28 23190.
**With regard to steel boats, it is vital that special attention is paid to areas around the water line. These are particularly vulnerable but receive no protection from anodes above the water line.
***All MGDuff anodes will suit wood, GRP or steel hulls. For aluminium hull anodes please contact one of our branches.
Do not mix and match aluminium, zinc or magnesium anodes on the same boat.
