Boat Maintenance

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.

Letters from the August 2010 issue of Practical Sailor. Subjects include: Shore anchoring, feathering props, earth-friendly cleaning products, staying hydrated and dink repairs.

In our search for the Holy Grail of prop paints, Practical Sailor testers delved into specialized multi-part coating systems. In the spring of this year, we had Matrix Engineering Concepts Mussel Buster Prop Coating applied to the propeller of our Union 36 test boat. Prior to that, the prop had been the test platform for Oceanmaxs Propspeed, which we featured in the November 2006 issue. In this report, we take a look at the newer product, Mussel Buster, and its application, and will weigh its pros and cons against other prop coatings, including Propspeed, Interlux Trilux Prop & Drive, and Pettits Alumacoat SR.

Letters to the editors of Practical Sailor in July 2010 include questions and comments about mildew, galley blenders, teak cleaners, online captains courses and personal hydration.

In January 2009, Practical Sailor tested 14 mold and mildew cleaners, and two household products stood out: the super-chlorinated Klean-Strip Mildew Stain Remover and Spray Nine, a chlorine-free household cleaner. After that test, several readers asked about products to prevent mold. One product in particular, Concrobium Mold Control, was repeatedly suggested for testing. We found Concrobium at Home Depot, and to make things interesting, we included two other mildew preventers that readers suggested: 3M Marine Mildew Block, a treatment formulated to follow the 3M Mildew Cleaner tested in January, and Mold Off, a product billed as an eco-friendly commercial-grade cleaner and protectant.

For many sailors, boatbuilding can be the ultimate do-it-yourself project. The skills derived pay off as extra dividends when it comes to repairs or fitting out projects aboard larger sailboats. And as Matt Zephry and his 12-year-old son Alex found out, sharing the boatbuilding process with a loved one is like passing along an important piece of family history. The father-son duo began their boatbuilding project without any plans. Their intention was to create a boat that was easy to row and could double as a sailing skiff for father-and-son fishing trips. Their dream boat-and first boatbuilding project-was a success, and the Z&S team launched Odyssey in time for a Fathers Day sail.

Weve touched up our varnish, slapped antifouling on the hull and, brightened that bootstripe. Now what to do with those half-full coatings cans? Its not too late to save some bucks next season by making sure the cans wont skin over or go clumpy. The trick is to chase out the oxygen. We could dump marbles into the can to fill up the remaining air space or transfer the contents to a smaller can from the local paint supplier. Instead, following a suggestion from several readers, this year, we pumped our half-empty cans of finish with Bloxygen.
