VETUS Aluminium Hull Anode

For vessels which mostly cruise on inland (fresh) waters, we
recommend aluminium anodes, since aluminium has a greater
difference of potential with other metals than zinc. This is very
important, as fresh water provides a higher electrical resistance
than salt water.

Cathodic protection by means of anodes is a must for the protection
of all metal parts under water. Therefore, not only for steel
boats, but also for wooden, fibreglass and aluminium hulls, anodes
are required. VETUS aluminium anodes consist of an
aluminium-indium-zinc alloy Mil – A – 24779 (SH). All VETUS anodes
are streamlined and mounted either with specially made studs, which
can be welded to a steel hull, or special through-hull bolts for
fibreglass and wooden boats. VETUS supply these studs and bolts
separately.

When ordering, please always specify the material of the hull. All
metal parts must have a direct contact with the anode. Therefore
the bolts supplied for e.g. fibreglass hulls must have a
wire-connection, so that contact can be made with the metal parts.
On fibreglass and wooden boats only the metal parts must be
protected.

The anodes are supplied excluding connection kit. For anode type 8
you need one connection kit. All VETUS anodes have a protective
layer of paint at the mounting side to prevent damage to the paint
work of your boat.
