He sails a Sparkman & Stephens-designed Yankee 30 out of St. His weekly blog Inside Practical Sailor offers an inside look at current research and gear tests at Practical Sailor, while his award-winning column, "Rhumb Lines," tracks boating trends and reflects upon the sailing life. Coast Guard 100-ton Master license, has logged tens of thousands of miles in three oceans, and has skippered everything from pilot boats to day charter cats. Practical Sailor is edited by Darrell Nicholson, a long-time liveaboard sailor and trans-Pacific cruiser who has been director of Belvoir Media Group's marine division since 2005. Its independent tests are carried out by experienced sailors and marine industry professionals dedicated to providing objective evaluation and reporting about boats, gear, and the skills required to cross oceans. Supported entirely by subscribers, Practical Sailor accepts no advertising. Practical Sailor has been independently testing and reporting on sailboats and sailing gear for more than 45 years. Other monitors were much easier to manage, and could be installed and calibrated by any handy boater who is capable of closely following instructions. Some units were clearly too challenging for most boat owners to install and calibrate themselves, and the units were so poorly supported that the average do-it-yourselfer would soon become frustrated. It was in these areas where we found a rather broad disparity between the different manufacturers. Voltage meters are also used to indicate battery state of charge.

Digital Battery Discharge Level Display, Electric Vehicle Fuel Meter. Testers spent time analyzing the potential difficulties with installation and what the manufacturer provided to facilitate installation, including a wiring diagram and calibration instructions. A hydrometer cannot be used with sealed, AGM or gel cell batteries. Model TQZN-12 and TQZN-24, 12V / 24V Digital DC Voltage Indicator, Solar Power Controller. The need to recalibrate this equipment as batteries age cannot be overstated, if extreme accuracy is desired. We found that all of the units were quite accurate, but understand that this was a very controlled test using new equipment, most importantly, a new battery. We compared these values as we timed the constant 12-amp draw. We ensured that for each product tested, our battery was at full charge, and we monitored both amp draw and voltage levels as we discharged the battery. We confirmed voltage and current draw using a Fluke Model 867B graphical meter and a Blue Sea Systems Model 8110-amp clamp/multimeter. ![]() This setup created a 12-amp DC load on the battery. Our test gear comprised a ProMariner ProNautic 12-40P battery charger West Marine-branded, flooded-cell, deep-cycle battery with a 75-amp hour rating and two 120-volt, 70-watt incandescent light bulbs powered through a Heart 140-watt DC to AC inverter.
