A little work around the house.

Nobody likes house work (no normal person anyway). And even fewer people like watching videos of house work being done. But I thought this one was pretty cool.

I’m not going to go into all the details of why a boat has zinc plates on them. It’s part magic and part science as far as I know. But basically, the zinc is a weak sauce metal that corrodes faster than the other more expensive more important metals on the boat, like the prop shaft, prop or through hulls. So as with most things in nature corrosion takes the path of least resistance and corrodes the zinc plates first before attacking the other stuff. This of course mean that from time to time, usually about once a year, we have to replace our old worn out zincs. They are cheap, $20 buck or so each, but it has to be done.

In order to be effective they have to be under water. The easiest, driest way to change them is to do it while the boat is out of the water. But since that only happens maybe once every 4 years, the other options is to pay someone to SCUBA dive down and do it for you or, if you have your own SCUBA gear, do it yourself.

Since we have our own SCUBA gear, we did it ourselfs. I did it last time and this time was Tawn’s turn.

So with nothing to do while she worked, I grabbed the camera, stuck it underwater and filmed her as she replace the old prop zinc with a new one.
