We started smelling a bad odor a couple hours ago. It was clearly coming from our boat because we didn’t smell it outside.

After flushing the heads a lot (even though they didn’t seem to smell), we thought the odor might possibly be coming from the sink in the galley. But it didn’t really stink either.

Several hours went by and Michael mentioned the smell again. I then realized that it smelled like sulfur. That led us to look at the house batteries. (We had been trying to figure out for some time why we had to run the generator so much to maintain a charge but hadn’t found the source of the problem.). Turns out one of the three house batteries had failed.

Our theory is that because the battery charger had been removed from the boat the voltage was drained down too much when the boat was in the Seychelles. It was just a matter of time.

We disconnected the battery cables from the battery terminals. We are now using just two house batteries. The voltage already looks better than it has.
