Energy is the heart of any eco-friendly sailing program, and heavy consumers of electric power will want an efficient battery charging system if they intend to remain off the grid for long periods. How effectively a wind generator can help meet your energy needs depends on where and when you plan to cruise (see PS April 2018, “Choosing a Wind Generator”).
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 mechanisms. Fossil fuels seem the most obvious, but in fact that represents only a tiny portion of the total. Most found its way into carbonates sediments, including limestone and sandstone. Plants, […]

However, if you use less than 20 percent alcohol or glycol (after dilution with water left in the system) you are at risk of biological growth; the lower the concentration the greater the risk. This is the reason why vodka and other alcohol-based winterizing fluids should be avoided. In our testing these solutions acted like an invitation to a microbial feast.
