MgDuff Magnesium Round Hull and Rudder Anodes – Dish-Shaped, Ø100–150 mm, MD56 / MD58

The MgDuff Magnesium Round Hull and Rudder Anode is a sacrificial anode designed to protect metal components of boat hulls and rudder blades against galvanic corrosion. Manufactured from magnesium, the range is intended for freshwater applications.

The anode features a round, dish-shaped profile designed to minimise water resistance when installed on underwater surfaces. Two models are available: MD56, measuring 100 mm in diameter and 25 mm in height, and MD58, measuring 150 mm in diameter and 35 mm in height. Both versions feature a central mounting opening.

Dimensions and Model Selection

The MD56 and MD58 models differ in their external diameter and overall height. Dimensions are specified as diameter × height.
- MD56 (1786): Round magnesium anode measuring Ø100 × 25 mm.
- MD58 (1787): Round magnesium anode measuring Ø150 × 35 mm.
The MD56 has a diameter of 100 mm and a height of 25 mm, while the MD58 has a larger diameter of 150 mm and a height of 35 mm.

When selecting a replacement anode, compare the diameter, height and mounting arrangement with the existing installation.

Construction and Mounting

The MgDuff magnesium anodes feature a round body with a dish-shaped profile. This design is intended to minimise water resistance when installed on the hull or rudder blade.

Both models feature a central mounting opening. The diameter and height of the anode vary according to the selected model.
- Anode Material: Magnesium.
- Body Shape: Round.
- Profile: Dish-shaped.
- Mounting Feature: Central opening.
- Installation Location: Boat hull or rudder blade.
Galvanic Corrosion Protection

The magnesium anode acts as a sacrificial component, corroding preferentially to help protect other metal parts of the vessel against galvanic corrosion.

The range is designed for hull and rudder applications in freshwater environments. Its dish-shaped construction is intended to limit water resistance while providing sacrificial protection for underwater metal components.
