PSs Best Practices to Combat Fuel Problems
Additives can’t solve real gasoline-quality problems. At best, consider additives to be only a final tweaking opportunity, something to supplement the following fuel management practices.
Marinco’s Shorepower Solution
We’ve seen a slew of new shorepower cords, plugs, and accessories coming onto the market in recent years, and with good reason. The majority of AC-related onboard electrical fires occur at the vessel’s shorepower inlet. The twist-lock connector used in shorepower cords and at the boat outlet has been around since the 1930s, and the design has seen little updating to make it better suited for use in the marine environment. The electrical contacts are small, exposed to the elements, and often required to support the plug and cord, all factors that beget corrosion and loose connectors, which can lead to electrical arcing, overheating, and fire.

SpeedsealLife Kit Test Update
In the Practical Sailor August 2010 issue’s Chandlery, we reported on the installation of a SpeedsealLife kit aboard one of our test boats, a Union 36 sloop powered by a 43-horsepower Beta Marine inboard. An improvement on the original Speedseal (PS, July 15, 2005), the SpeedsealLife is designed to extend the life of a water pump impeller, even in a run-dry situation.
Y-valve Installation Advice and Troubleshooting
All waste plumbing hoses should be kept as short and straight as possible with no dips where waste could collect. The diverter valve should be located for easy access to the selector handle and free of other stored “stuff” that could bump the handle. The handle positions should be clearly marked for no confusion as to tank or overboard. Before mounting, make sure there is enough room for all three hose fittings and hose bends. Use 120- or 90-degree hose fittings where necessary to prevent tight bends in discharge hoses, and make sure to use the correct reinforced hose designed for sanitation systems.
Y-valves Under Pressure
Continuing with our most recent evaluations of marine sanitation systems, Practical Sailor tested eight marine-grade diverter valves (Y-valves), the valves that control the flow of liquid from one source to two different outlets or from two sources to one outlet. The test field comprised seven manual diverter valves and one electric valve from seven manufacturers. Testers looked at construction, performance, ease of use and install, price, and warranty. The manual Y-valves tested included products from Bosworth Co., Jabsco, Forespar, Groco, Johnson, Whale, and Trudesign (distributed in the U.S. by Raritan). Testers also looked at an electric Y-valve from Trudesign.
Marine Sanitation Hose Test
Sanitation hoses are specifically designed to contain odorous gases. They are made of very different materials than the many similar-looking hoses used for fuel, coolant, and potable water—and they are not interchangeable. In a home, sewage is contained by rigid metal and PVC pipes, materials that are not practical on a boat. So what are the best hoses to use in an onboard waste system? Practical Sailor tested hoses made of butyl rubber, white vinyl, and polyurethane from Raritan, SeaLand, Shields Marine, and Trident to find. This report covers the test results at the one-year mark.
Installing Hoses Highlights Their Differences
While model holding-tank testing allows side-by-side comparisons, there’s nothing like on-the-boat testing to sort out practical differences. Our test boat, a PDQ 32, had been plumbed with a mix of low-end vinyl sanitation hose and water exhaust hose; the rubber hose was permeated, cracked, and discolored, and the sanitation hose was permeated to the point of having a thin film of sticky goo that had condensed on the external surface. A textbook case of time showing the weaknesses of poor material selection.
Worthwhile Advice from Hose Manufacturers
Before starting most tests, we like to interview the participating manufacturers. Below is a rundown of some advice we gleaned from the waste hose manufacturers.

There are two primary reasons why U.S. boat owners are required by law to display the familiar “Discharge of Oil Prohibited” placards aboard. For one, it serves as a reminder that we all must do our part to help protect the environment. Secondly, it helps enforcement officials because those carrying the placard can’t plead ignorance of the Federal Water Pollution Control Act.

Union 36 Used Boat Review
While not the best boat for light-air sailing, the Union 36 is a good sailboat for the bluewater cruiser. It wont get you there fast, but it will get you there comfortably and in one piece. The boats teak decks and lavish use of interior wood is attractive but requires much upkeep and maintenance. A product of the Taiwan-U.S. boatbuilding industry, the Union 36 is a heavy-displacement, full-keel, cutter-rigged double-ender designed for ocean sailing. The Union 36 is nearly identical to several other boats built during the same period: the Hans Christian 36, Mariner Polaris 36, and the EO36. According to well-known naval architect Bob Perry, the Union 36 and its cousins are all based on the design of a 34-footer that Perry was commissioned to create back in the early 70s.
