FAQ:

Q: What do anodes do for boats?

A: By definition an anode is an ingot of sacrificial metal attached to the underwater hull of a narrowboat or canal boat which corrodes due to electrolysis more readily than the hull and propeller. Magnesium anodes are used for boats in fresh water. Aluminium anodes are used for boats in brackish water.

Q: What are anodes and how do they work?

A: Anode The anode is the positively charged electrode. The anode attracts electrons or anions. The anode may be a source of positive charge or an electron acceptor.

Q: What exactly are the anodes purpose?

A: Anodes are a component of batteries and of electrically-charged tanks that are used to polarize or deposit layers of various metals. There are also a number of devices that use special types of electrodes, called sacrificial anodes, to protect other metal components.

Q: What are Zincs on a boat?

A: Maintaining the sacrificial anodes, commonly referred to just as “zincs,” on your boat is an essential part of keeping your boat in top shape. Zincs are what protect your underwater metal boat components from galvanic corrosion. Zincs need to be replaced when about half of the anode has corroded away.
