Seawater and electricity love each other with a fatal attraction, and when they break barriers to get to each other, we suffer from the destruction left in their wakes. Enter aerosol corrosion inhibitors. If you spray sensitive electrical circuitry-including printed circuit boards-with the aerosol rust inhibitors we tested, theyll prevent corrosion from interrupting circuits and water from creating circuits where they arent wanted. Our test lineup included Boeshield T-9, Corrosion Block, CorrosionPro Lube, CorrosionX, CRC Heavy Duty Corrosion Inhibitor, CRC QD, LPS 1, Strikehold, TC-11, WD-40. The TC-11 was our top pick.
Minn Kota's 3X steering and ergonomic features push the RT80/S-3X past the competition in the 80-lb. thrust class. In the 50-lb. class, we like the no-frills MotorGuide SW46 HT.
Sanitation systems aren’t the sexiest part of sailing, but they are, well… necessary. And although the risk of transmission of COVID-19 through means other...
When we last touched on electric propulsion conversion in September 2008, PS noticed several small companies catering to the niche. Among them was Above the Waterline Marine in Santa Barbara, Calif. (www.abovethewaterline.net). Owned by James Lambden, the company specializes in alternative energy systems; it also builds and markets an electric propulsion system, made by subsidiary Propulsion Marine.
According to multiple reports, most AC electrical fires occur at the boats shorepower inlet. To address this and other shortcomings of the standard twist-type boatside connection, SmartPlug Systems developed a new AC shorepower system that the company hopes will become the new marine standard. Loose and corroded connections are most often the culprits when overheating occurs. Corrosion typically results when moisture gets in at the plug-inlet connection, while arcing-which in turn leads to pitting, scorching, and heat build-up-is partially due to the shape and small contact area of the connector pins.
The bigger the joker valve, the less chance of clogging.
Everyone hated the first generation of CARB gas cans. Intended to reduce volatile emissions by recovering vapors and reducing spills, they did exactly the opposite. The nozzles were cumbersome, hard to control, and fragile. Pouring was slow and spills increased dramatically. Many, like us, resorted to hoarding older non-CARB cans with user-friendly spouts, collecting them […]
Todays 9.9-horsepower four strokes pack just the right amountof punch for a portable dinghy engine. The downside, as you may have guessed, is their hefty weight. The three Practical Sailor tested range in weight from 82 to 92 pounds. All are two-cylinder, water-cooled engines that take about a quart of oil, and all are pull-start models, with chokes that need to be used only when the engine is cold. All come with a standard 3.1-gallon plastic fuel tank, a fuel hose, and an aluminum propeller. In terms of propulsion, none of these portable outboard engines has it all. So after evaluating how easy each was to operate, transport, store, and maintain, we based our recommendations on weighing each engines pluses and minuses.

Reverse-osmosis watermakers run from $3,000 to over $8,000, and though many are similar, close examination is required for the buyer who wants the right one for his or her onboard needs.
