Bonding, Grounding and My Boat's Anodes?

I love it when readers write in. Eric wrote in over the weekend with what I think actually ends up being three good questions. One of them has to do with bonding and grounding, the other anode consumption, and the third with transducers and fairing blocks. For those of you who have no idea what the bonding system on your boat looks like, the photo below shows a green wire connected to a sea strainer. That wire is there to attach the strainer to the boat's bonding system.
