Subscribers Only In some ways, the good old days just werent that good. Just ask any old salt who has watched an expensive canvas dodger mildew, rot, and fall to pieces. When Sunbrella entered the market four decades ago, the strides forward were significant. When it comes to fabricating a long-term, waterproof fabric cover, its hard to beat the combination of vinyl and acrylic or vinyl and polyester. Practical Sailor compared Sunbrella, Sunbrella Plus, and WeatherMax in a long-term field test and some creative bench tests. Testers compared weight, sewability, breaking strength, water shedding, permeability, and price.
Subscribers Only Two years ago, we sewed up our own dodger and assorted deck covers made from Sunbrella and WeatherMax fabrics and monitored how well the materials stood up to 24/7 weather exposure and the extreme climate flip-flops of the mid-Atlantic region. On a parallel track, we did some controlledand creativematerial testing restricted by tight budget constraints. For example, we lacked an Instron tension test machine to carry out a formal ASTN D5034 elongation and breaking strength test, so we did the next best thing: We made our own.
To keep your Biminis, dodgers, and sail covers clean and in service for the long haul, regular maintenance is a must. Here are some best practices and care tips we’ve picked up over the years.
Subscribers Only In the November 2011 issue, we compared the chart-plotting features of four small-screen plotter-sounders from Garmin, Humminbird, Lowrance, and Raymarine. In this article, we look at the fundamental sounder functions of five plotter-sounders, priced from $700 to $1,500. The high-end products in this test, the Raymarine A70D and the Garmin 740S, have larger, high-resolution screens, can handle 3D charts, and are designed to network with wind instruments and autopilots. The smaller units were the Lowrance Elite-5, the Humminbird 788ci, and the Humminbird 798ci SI, which has side-imaging capability; these are marketed mostly to anglers. Units were tested for screen visibility, sounding capabilities, and user-interface.
Subscribers Only In May 2010, Practical Sailor reviewed a prototype man-overboard (MOB) recovery device called the Seascoopa. The parbuckle-type device functions much like a human trawler net, enabling the recovery of injured or unconscious MOBs while the boat is slowly making way. While the device performed as advertised, it needed some design fine-tuning. After an extensive re-design, the production version of the new Seascoopa addresses most of the concerns testers had with the prototype and cranked the construction quality and design up a notch. Testers felt there are certain benefits to the improved Seascoopa that other recovery aids do not offer, but it's not our preferred device for use as a primary MOB aid.
Subscribers Only Practical Sailor treated used running rigging with Downey fabric softener, Grangers 2-in-1 Cleaner and Waterproofer, and Nikwax Rope Proof to determine whether softeners or waterproofing treatments improve the performance of nylon and polyester double-braid lines on a boat. Can aftermarket treatments improve line handleability, reduce water-weight gain and strength loss, and prevent lines from freezing in colder climateswithout damaging the lines? We also wondered whether any treatment would keep aging lines from squeaking as they run over blocks under high strain. Our tests found the definitive answer.
Subscribers Only Practical Sailor followed manufacturer instructions for treating used lines, with one exception. Both the Grangers and Rope Proof advise users to dry the treated ropes in a warm dryer after soaking them in the diluted solution and laundering them. As weve learned in past tests (PS, July 2011), most rope manufacturers caution against placing rope in a heated dryer, and cleaning them in a washing machine can be damaging (to the rope and the machine). So for this test, we opted to clean the test ropes by gently agitating them in a bucket by hand, rinsing them in a pillowcase on a shortened gentle cycle, and air drying them. (We did test one set of lines by air-drying and heat-setting, but there was no measurable difference.)
Subscribers Only Titanium is of particular interest to sailors due to its resistance to galvanic corrosion. It has the highest strength-to-weight ratio of any metal and is non-magnetic. It is up to 20 times more scratch resistant than stainless steels. Practical Sailor contributor Patrick Childress takes an in-depth look at the metal and its use in the marine industry as his boat, a Valiant 40, is refitted with titanium chainplates and other rigging.
Subscribers Only Titaniums high price is only one thing that is keeping in the realm of mega-yachts and Cup boats. Some of the essential roles that lightweight metals once played in deck hardware are now being taken by high tech fibers like Spectra or Vectran. Carbon fiber laminates are also taking the place of metal fittings, at a slightly lower cost. Nevertheless many manufacturers see a bright future for titanium. Here is some feedback we got from manufacturers on this topic.
Subscribers Only Stainless steel is exactly what the name says; the steel stains less. As PSs February 2007 special report Marine Metals Warning, pointed out, stainless steel is not the maintenance free miracle material many boat owners imagine it to be. Some stainless steel is more stainless than others. With over 500 different grades of stainless steel, only a few meet the mark for use in the corrosive marine environment. Most marine stainless steel is grade 304 or 316. Stainless steels are made up of metals with a blend of iron, chromium, and nickel. Chromium resists corrosion, and nickel resists acids.
Subscribers Only No good ever comes of fouled diesel fuel. One of the best ways to keep fuel free of contamination issues like condensation buildupand the bacteria growth it promotesis fuel polishing. Fuel polishing in its most basic form is the act of circulating the diesel in your tank through a filter. The Parker FPM-050 diesel fuel polisher is designed to be plumbed into the fuel supply line between the existing primary fuel filter and the engine. Testers plumbed the FPM-050 to recycle fuel into a container for several days. Testers looked at flow rates, contamination, sludge, ease of installation, and price.

Its a good idea to keep expired flares on hand to use as backups (on board or in a vehicle), but be sure to store them in a clearly labeled container separate from your current flares. If you find yourself with an overstock of oldor unwantedhand flares, however, you must dispose of them properly. Unfortunately theres no set agency that deals with expired flare disposal or recycling. Because state and federal laws pertaining to flare disposal and transportation vary, theres no single disposal policy.
On Oct. 31, U.S. Sailing released independent reports on three highly publicized sailing accidents that happened this year. Practical Sailor has been closely following the WingNuts capsize, in which the captain, Mark Morley, and Suzanne Bickel died of “head injuries and drowning,” while still tethered to the boat, and six crew were saved by fellow racers. Practical Sailor Technical Editor Ralph Naranjo served on the U.S. Sailing panel; his focus was on the weather and the boat design features that led to the accident.

Technical Editor Ralph Naranjos recent market survey of mechanical rigging terminals in the June 2015 issue of Practical Sailor demonstrated just how long these terminals can last if they are installed correctly. That report came close on the heels of rigger Brion Toss photo essay on what can go wrong if they are not assembled correctly, or assembled without any sealant. Yet manufacturer's are still not entirely clear where they stand on the use of sealants in these fittings.
