I have a total of 8 anodes on my 32 feet bilge keel steel
boat, small one on rudder
and small one wired to shaft, two fish
shaped ones either side of the skeg and and the same either side of each keel
. First two are still ok after 5 years the rest will need replaced next year. The boat is kept in a half tide harbour for 5 months a year. Do I need this many anodes fitted to the skeg and keels. My only concern is the replacement price
. They have went up 300% in the last couple of years along with all types of metal.
