Yet another anode question

[pheran]

Do I need them on a steel hulled boat?

 

[Robin]

Yes yes and again yes!

Probably about 3-4 each side of the hull, 1 on the prop, and 1 each side of the rudder! get ready to dispose of lots of beer tokens: /forums/images/graemlins/smile.gif

I have 4 each side of my hull/keel, 1 each side of my rudder and one each side of the rudder skeg, attached to M10 studs welded to the steel plating.

Deciding how many is a bit of a black art but there was a very informative thread a little while ago.

Give MG Duff a call and they'll help with what you need and where. You definitely need anodes!

Oops. And there's me thinking they were probably only required on plastic boats. Many thanks for everyone's input.

Would be very surprised if the boat is not already fitted with anodes, although if it is in fresh water they would be magnesium not zinc. If you are not getting problems with galvanic corrosion on props and other bronze fittings (if you have them) there may not be a need for more anodes. As suggested, find out what you have and if you need advice contact Duffs.
