The cover does not have to be some elaborate, fiberglassed or custom-made battery containment system. A simple piece of plywood covering the tops of the batteries will work. All your surveyor wants is to prevent any possibility of a dropped metal object, tool or part falling upon the terminal posts. ABYC requires that all 12 volt positive connections be protected from possibility of accidental contact. Of course the batteries must also be secured so they cannot shift in rough conditions. So the requirement to secure the batteries combined with the requirement to protect the terminals usually means a overall containment system. In my boat, the only covers over the tops of the house battery is the plywood floorboards of the engine room. Joe Engel Portland, OR

True. And a some penetrating epoxy soaked into the plywood will protect it indefinitely from the battery acid that will inevitably get on it.
