Interesting Nautical Fact of the Day...

It wasn't until the invention of copper hull plating that the Toredo worm became less of a problem. Copper plating? That would kinds dull their fangs, I'd imagine... Mariners long ago discovered that one of the natural properties of copper was it's ability to kill off bacteria preventing it from growing on it's surface. Copper plating was used, later replaced by anti-fouling paint with very high copper content (until it was banned). Makes me wonder about any potential health hazards due to the increasing practice of replacing copper pipes with PVC in the water supply side of new homes. One word - cheaper. |
