Battery power has come a long way, whether considering automobiles, power tools, lawn and garden equipment, or marine outboard motors. Cost parity between electric...

This article launches Practical Sailors long-term test of electrical wires, electrical connections, and corrosion inhibitors for electrical applications onboard sailboats. Ultimately, the goal of this ongoing project is to examine corrosion in wires and connectors in a marine environment. More concisely, it could be presented as a closer look at three common elements in marine wiring to answer some basic questions: What is the best wire to use on a sailboat? Is it tinned wire, automotive wire, or stranded machine tool wire? What are the best corrosion preventatives? Do you apply the anti-corrosion treatment to every connection and every crimp, or just certain types of connections? What are the longest-lasting connections? Which were most prone to electrolysis? We made observations during the six-month test period without disturbing the samples. At the end of the full one-year test period, we will unbolt all of the fittings from the terminal strips and look for corrosion under the fittings.

“Yay! Another article about blackwater holding tanks!” Said no one ever. This is nobody’s favorite subject, but like it or not, responsible waste management...

We often get this question. My car has air conditioning when Im running down the street so why can't my boat? First, your car only has air conditioning when the engine is running, which works out fine because we only need air conditioning when the engine is running. Second, the air-conditioning load for the car is a tiny parasitic load compared to the power required to drive the car down the road. Its actually less than the increased drag caused by driving with the windows rolled down. Thus, it is more or less an engineering afterthought with regards to the energy balance of an automobile.

The tools and materials required to maintain and repair everything on a boat will barely fit in a room. Just the kit required to maintain vital systems will raise the waterline of a large boat and is impractical in a smaller boat. Fortunately, when day sailing and even cruising locally, all we really need to do is get back to the dock...any dock.

When summer comes, a dozen or more sparkling white lights will adorn every popular anchorage. Visible from miles away, they promise to provide good...

Any sailor who has tried to wrestle a full-keel ketch with a barn-door rudder into a tight slip has probably wondered if they could...

So, you’ve finally purchased that new (or new-to-you) boat of your dreams. Now is a great time to familiarize yourself with its systems—a good...

If youve followed the first two installments in this three-part series on ensuring safe, fresh-tasting drinking water onboard, youve cleaned your freshwater tank, pre-filtered all water going into the tank, screened the vent, and disinfected the contents. Now that the water has sat in the tank, its time for one more filtration process; this time, focusing on improving taste and eliminating micro-organisms.

Running the wires for new electronics requires your best cursing vocabulary, lots of sweat, twisting body contortions, luck, and the occasional bandage. For tips on how to make this job easier, we turned to PS contributor Bill Bishop. A professional marine-electronics installer, Bishop has many ingenious ways to thread a wire from point A to point B.
