Before diving into the topic of responsible boating, we’re required to say something about global warming and carbon. Primordial carbon was sequestered by several...

A new Lithium Iron Phosphate (LFP) battery is sold as having a stated storage capacity, such as 100-amp hr. In practice, however, there will...

In "How to Charge Your LFP Battery the Right Way" we explored the charging needs of LFPs and how smart chargers, fed from shore...

Everyone hated the first generation of CARB gas cans. While they were intended to reduce volatile emissions by recovering vapors and reducing spills, they...

If you are thinking of managing a conversion of your own existing, all lead acid system over to one with a Lithium iron phosphate...

The crud that is clogging my filters are microrganisms, primitive creatures that live in water and feed on oil, informally called “HUM-bugs.” The HUM stands for Hydrocarbon Utilizing Microorganisms. There are many kinds of HUM-bugs—bacteria and fungus (mold, yeast, algae, etc.). Some need oxygen, some don't. Many are airborne. Some thrive best in freshwater, some in salt. They all create thick slime, which helps them stick to surfaces and protect themselves from attack. It's unlikely that you can buy diesel fuel without getting some.

Marketing literature does a good job of promoting the primary advantages of lithium iron phosphate batteries (LFP or LiFePo4), such as life expectancy, weight,...

Early in the sailing season, the things we overlooked during winter storage can come back to haunt us. And with regard to our boat's...

Let's dig into the truth to the 75-80% power reduction claims for Energy Recovery Watermakers, review some comparison data, chat with the inventors, and...

After my experience last weekend while hunting down odors on our project boat, the 1971 S&S-designed Yankee 30 Opal, I thought I’d revisit some...
