The Mastic Treaty
Or Anode-r Half Day as it takes a long half-day to fit all of the 16 hull anodes. These are fixed with some mastic sealant to stop them vibrating as they erode and are locked off with medium strength Loctite.
We have been advised that where the disc anodes become too worn the bolt heads become acive and the anode drops off. Eventually the remaining studs have to be drilled out and then helicoiled to fit anodes again. This information immediately lead us to swap out a couple of older anodes.
