Boat Maintenance

In regard to the March 2014 wind instrument reviews: I installed a Garmin package, including a GWS10, a little over a year ago. The unit works well enough, but the flimsy windvane has fallen victim to birds three times. The biggest threat to a windvane is birds, not rough weather. This applies to all models, from a simple Windex (estimated life expectancy about three months) to the old Nav5 all-metal vane.

In November 2013, I bought a 65-pound Mantus Anchor. Living in Maine, I had not yet had the pleasure of using it but was disturbed by your recent report (PS, February 2014) regarding their shank strength. I contacted Mantus about getting a replacement shank.

During our April 2014 performance test of rubbing compounds, we sullied a dozen brand-new wool buffing pads, all of which were Shurhold brand. Since quality buffing pads are reusable (and not cheap), we thought the rubbing compound test was a great opportunity to also check out Shurholds new, professional-grade Serious Pad Cleaner (No. 30803). Mixed with water, this powdered concentrate is formulated to dissolve compounds and waxes from wool, polyester, cotton, microfiber, and foam buffing pads or cloths.

Over the years weve owned Josepheline, our 38-foot Lightwave catamaran, weve figured out a few simple fixes to some niggling onboard problems-some boat hacks, if you will-and we thought wed share a few in the hopes that other boat owners may benefit. If you have any little fixes of your own that youd like to share, email your story to [email protected].

Lately, readers have been asking us about which antifouling paints serve well for specific bodies of water (or type of water). So, in this article-our annual spring bottom paint report-we will try to answer these questions with some recent reader survey data and sales reports from the two biggest brands in the U.S. (Pettit Paints and Interlux Yacht Finishes). But before we get into the regional breakdowns, a quick recap on choosing bottom paint and our paint testing program is in order. If youre a longtime subscriber, feel free to skip down to the Current Testing section.

PS Reader Mark Baldwin wrote: "I used Uni-Gard pink antifreeze (rated for -50 degrees) to winterize my boat. The leftover jugs all froze solid at -14-or perhaps they froze before the night got that cold. The consequence for my boats systems? No telling until the spring, I guess."

Early this month, irate boat owners from Marina del Rey, Calif., packed the regional water-quality board meeting, protesting a rule that would require them to switch to a copper-free antifouling paint by the year 2024. The board unanimously voted in favor of the rule, moving it another step forward in the legislative process-a bureaucratic cricket match that will drag on for several years.

A lot can be learned from really small boats that carry no crew. In fact, sailing robotics-SailBot for short-is attracting sailors and engineering students from universities across North America and Europe. These competitive research programs are a proving ground for on-the-water autonomous craft, and they give us a glimpse of what the future of marine electronics may have in store.

Tankless propane water heaters carry serious risk of causing carbon-monoxide poisoning or oxygen depletion when mounted in a tight or sealed space. Because a boat is more tightly sealed than a shoreside home, the carbon monoxide is more likely to become trapped. Multiple boater deaths have been attributed to tankless water heaters, and several brands have been recalled over the years-among them Wolter Water Heater, Paloma, and Rheem-Rudd-because they posed a carbon-monoxide poisoning hazard.

Sailboats have a bit of advantage over their power cousins in that we have more high spots that can be used creatively. In my installation, the diesel vent line (fuel-grade hose) loops high inside at the transom and back down to the through-hull. Through the use of a check valve, air flows out, but intake air comes in through the AVD, which is attached to the underside of the deck; no additional support needed. The unit is readily available for inspection or replacement through the transom locker, and it is not in the way of any equipment that needs to go in or out. Love the H2Out AVD2 vent filter; kudos to Pindell Engineering.
