I had the bottom cleaned for the first time since purchase
yesterday and was told by the diver that:
1. There were no zincs on the boat - not even a trace on the end of the prop where one would normally be installed.
2. The prop was in great condition despite this.
3. There was something extruding from the hull
bow the waterline forward on the port side. He described it as a clear "window" in the hull
I had him place a zinc on the prop to be sure, but he thought what he saw there might be to prevent electrolysis
. I'm dubious, but thought someone might be able to tell me what I'm looking for to verify whether that's what this thing is that he's seeing.
From what he understood there's some type of system that will prevent electrolysis
via some method other than traditional bonding with zincs. He mentioned that all my thru hulls might be bonded together on the inside. He couldn't even say what the system would be called, so I'm at a loss as to what to even look for. Can anyone shed some light on this?
