Boat Maintenance

Letters to Practical Sailor, October 2010. Subjects include an owner's comments about MacGregor boats, digital maps, teak cleaners, props and adhesives.

Not only do bilge pumps serve to clear incidental water, but they can also give the crew extra time when a boat is taking on water-time that can be spent repairing a leak, donning life jackets, or making a distress call. Practical Sailor tested more than a dozen centrifugal pumps from Attwood Marine Products, Rule/ITT Corp., Shurflo, and Johnson Pump. In this report, we look at the eight higher-capacity electric bilge pumps (output rated at or above 1,600 gallons per hour, or GPH) and see how they fared in exhaustive bench testing. A follow-up report next month will examine pumps rated for 1,500 GPH or less. Testers measured bilge pump flow rates and power ratings at two voltages and tested for compliance with the American Boat and Yacht Councils standards for dry run performance. In the final analysis, we picked the best bilge pump based on performance, warranty, wiring, and price.

Gelcoat, particularly porous gelcoat, requires a more specialized wax than what youd use on your car. And while most of the liquid waxes we tested are liquid polymers designed specifically for gelcoat surfaces, we also tested some automotive waxes to see how theyd fare against the best marine waxes. These test products are designed to be the final layer of hull protection applied to a new boat or to a boat with oxidized gelcoat that has been thoroughly compounded and polished to a smooth, shiny finish. We tested liquid waxes from Star brite, Cajun Shine All, Collinite, 3M, Mothers, Restructure, Interlux, Imar, Nu Finish, Flitz, Yacht Brite, Woody Wax, Marine Shield, Meguiars, Flagship, Glare, West Marine, Turtle Wax, Island Girl, MP Pros, and Zaino Brothers.

Practical Sailor offers the annual selection of Editors Choice products for the Gear of the Year 2010 lineup. We hope the list will guide you through the dizzying array of gear at the fall boat shows, or at least help you whittle down your wishlist for Santa. The roster covers a broad spectrum of products-from gadgets for measuring speed to a performance multihull built for speed-that have bested their peers in our tests. The lineup includes gear from Spinlock, Brion Toss, Lopolight, Selden Mast, DuBarry, Keen, Standard Horizon, and Mastervolt. It covers LED navigation lights, bosun chairs, footwear for sailors, and marine electronics. Boat maintenance products from Polymarine and Interlux also made the list.

Letters to Practical Sailor from our readers. September 2010's topics include barnacles, teak finish, knots for a bosun chair and LEDs.

I use Collinte’s No. 885 Heavy-duty Fleetwax in the Chesapeake Bay area, and I’ve been impressed with how well water still beads each spring as I wash the hull in preparation for a new coat. But no matter how nice the shine, black streaks develop, starting with the first rain following waxing. I think the boat would look better with no wax than with wax with black streaks.

Originally designed for pumping operations on land, the Fast Flow engine-driven pump has a tremendous pumping capacity, with the ability to move nearly 5,000 gallons of water per hour (at 800 rpm). Thats nearly five times the amount of the average electric bilge pump. The Fast Flow Pump comes in a variety of sizes, but a close look at installation and fittings is necessary to determine if the pump will fit on a particular boat.

Practical Sailor rounded up seven readily available marine sealants and adhesives, including products from 3M, West Marine, BoatLife, and Sika Corp. The test included four polyurethane-based products, one silicone product, one polysulfide caulk, and one polyether caulk. Testers found that not all caulks will work for all applications. For example, the versatile polyurethane 3M 4200 was fast drying but didnt adhere well to wood, and all polyurethane products have to be kept away from acrylics and Lexan surfaces. Products tested were: 3M 5200 Fast Cure, 3M 4200 Fast Cure, West Marine 8200, Sikaflex 291 Lot, 3M Silicone, BoatLife Life-Caulk, and West Marine Multi-caulk.

For those of us who spend nearly as much time under the water as on it, the Liquid Image 310 video mask sounded like a great addition to our diving kit-and a good fix for our gadget addiction-so we had to give it a try when we came across it at a spring boat show.
