Q: I have a 38ft ferrocement long keel yacht in salt water, please advise type of anodes required

Cathodic Protection for a Ferro Cement vessel is the same as Cathodic Protection for a GRP vessel. We are only looking to provide protection to the prop and shaft, but there are special considerations. Please see the Ferro Cement technical download

Protection is based on the prop size. For props of around 10-20" in diameter we would use a ZD77 anode, and would also suggest a shaft anode to go with this. This would provide a seasons protection
