Our current marina is located inside of an estuary. Filled with mangroves and even some crocodiles, the water has a visibility of about zero. It’s muddy and coconuts and other debris float by with the tide. Sometimes the coconuts knock against the hull and more than once have we thought somebody was coming to visit.
Camille gets pretty bad “ring around the tub” – what we call it when the white part above the waterline gets brown – and grows a lawn of marine freeloaders on her underbelly. All of this is not good for her gelcoat and fiberglass. If left too long it can leave permanent damage.
When at anchor in clean water, we usually scrub our own bottom (the part of Camille that is underwater) to remove marine growth. But in this water we let the professionals come out and scrub her up. At a dollar a foot it’s really not a bad deal. Guillermo comes out with his team of helpers and the three of them get to scrubbing, scraping and poking for about an hour.
The divers also inspect the sacrificial anodes (commonly known as zincs because that is the material they are made of) and replace them as needed. Good zincs are very important because they work by dissolving (or sacrificing) themselves, before the piece of metal that they are attached to does due to galvanic corrosion. We have zincs attached to the propeller shaft and the strut which holds the propeller shaft.
We don’t have much of a schedule for getting the bottom cleaned – just whenever the ring around the tub gets too ugly. How often do you clean your bottom? Do you have a set schedule or just wait until it needs to get cleaned?
