Boat Maintenance

The January 2010 issue of Practical Sailor features letters on such subjects as: orbital polishers, seasickness, MOB technology and heads.

The new line, Scotch Tough Duct Tapes, includes: a new No Residue tape, said to handle temps up to 200 degrees, that can be left on for up to six months without leaving a sticky mess behind; an Extreme Hold tape, which uses a double-layer adhesive for a better grip that wont fail under pressure; a Heavy-duty All-Weather tape designed for long-term (even permanent) exterior repairs that 3M claims will stand up to UV and moisture without cracking or peeling; and Outdoor Painters Clean Removal tape, which is marketed as a paint pros choice for high adhesion, waterproof backing, and clean removal for up to two weeks. The line also touts the first-ever transparent duct tape for "invisible" repairs.

Sight is the mariners most important sense, and tools that enhance visual acuity can be worth their weight in gold. Leicas newest addition to its line of premium-priced, high-quality optics delivers brilliant viewing-and at $2,200 costs nearly its weight in gold-but for the sailor preferring an uncompromising pair of binoculars, the German-made Ultravid 7x42 HD is a navigators dream. Although they lack a compass, they do afford camera-lens quality resolution and their low-light gathering ability is truly astounding. The ergonomic two finger-focus adjuster, water-tight armored coating, and extendable eye cups round out their superior design.

Exterior wood finishes-including one-part varnishes, two-part varnishes, synthetics, sealers and stains, and teak oils-were evaluated one year after application. Testers rated the wood finishes on ease of application, the integrity of the gloss and appearance, and how they fared over the 12-month period during which they were exposed to Florida sun and weather. Testers looked at color retention and gloss retention. After a year, 20 of the original 22 one-part varnishes were still performing well, and all six of the original two-part varnishes remained in the running. Varnish alternatives like teak oils and teak sealers struggled to make the 12-month cut, but the Cetol-coated panels still looked good. Products that were doing well 12 months after application included Interlux Cetol Marine and Cetol Marine Light, both with the clear gloss overcoat; Pettit Clear High Gloss and Pettit Wood Finish; Interlux Perfection; and Nautiking NautiThane.

I have a Pearson Ensign 1962 now at a slip in New Rochelle, N.Y. This season marked the first time we had the luxury of keeping our boat at a slip. In order to maneuver through the marinas byways without worrying, I bought a 24-volt Minn Kota outboard (80 pounds of thrust) and two 12-volt batteries, which I hook up in series. Not only am I able to stop start, turn, etc., in the marina, but-to my surprise-in the calm sound water, I can nip along at about 3-4 mph with myself, two crew, and the 3,000-pound boat. The result is that Ive only used my 5-horsepower Mercury outboard once this year. My electric outboard doesn't stall; it has variable speed like no ones business; reverses with relative ease, and is less expensive-though more cluttered-than the self-contained electric outboards you recently reviewed. Am I part of a growing trend or just weird? If the former then it might be worthwhile testing electric outboards for boats my size (22.5 feet) and commenting on their applicability.

To keep from being pulled under in a collision between a tanker and my sailboat, I "pulled the ripcord" to release the snap shackle on my Standard West Marine Safety Tether . The tether release lanyard was outfitted with a series of balls. (See bottom photo at right.) I had rehearsed reaching for and feeling the release toggle many times so it would come naturally in an emergency. The balls have a distinct feel. There was nothing on my PFD or foul-weather jacket that resembled them. The replacement tether I bought from West Marine (ISAF Specification Safety Tether, No. 9553504) has a new toggle on the snap-shackle release lanyard that consists of an open triangle of plastic. This is dangerous, in my opinion! In my first few hours of using the new tether, in moderate sea conditions, I managed to snag the triangular loop on something and release the snap shackle. I am now replacing all triangular loop pulls with bead pulls that I have crafted myself.

Practical Sailor testers compared Tackticks improved Race Master system to the Nexus Start Pack 3, a hybrid wired/wireless system. The Tacktick Micronet wireless wind instrument, a compact system featuring wireless display and a masthead sensor, has a strong following among racers. It has proven to be a good choice for those sailors serious about improving race performance as it has many options for tracking performance on the course in real time. Its ability to work with a 12-volt system makes it a good choice for small boats. The versatile, expandable Nexus hybrid has an impressive and intuitive interface and a graphic analog wind representation. It provides all of the basic functions a cruiser or racer uses most, and testers found the analog wind display appealing.

In August 2008, Practical Sailor launched a topside paint test in search of a high-gloss, easy-to-apply, durable coating for fiberglass hulls. The initial report focused on the application characteristics for 29 topside paints, including multiple white coatings and a handful of colored topside coatings. This report taps the best topside paints after their being exposed to the New England weather for a year. Testers rated each paints appearance, abrasion resistance, scratch resistance, hardness, and stain resistance. PS compared seven enamels, 12 mono-urethanes, eight two-part linear polyurethanes (LPUs), and two water-based paints. After 12 months exposure, the majority of the topside paint test field was holding up admirably. Test paints included products from Interlux, Crystalac, Epifanes, Insignia Coatings, Kirby Paint Co., Pettit, Sherwin-Williams, Signature Finishes, and West Marine.

Billed as the worlds only shorepower corrosion detector with reverse polarity indicator by West Marine, Marincos new Galvan-Alert attaches to your existing 30-amp shorepower inlet and power cord and monitors galvanic and stray current corrosion flowing through the green ground wire ground of your shorepower system. Appearance-wise, the GalvanAlert is similar to a miniature Marinco power cord. It is well constructed and utilizes the same plugs, connectors, and locking rings that are familiar to most every boater with an AC shorepower cord. The GalvanAlert has four LED indicators-a green LED to indicate power, a red LED indicating reverse polarity, and two other LEDs to show medium (green) and high (red) galvanic corrosion activity.

Practical Sailor tested bottom paints from seven major makers of boat maintenance products. In this report, we compare the 12-month performance of 39 ablative paints and 31 hard paints. We also offer the test results of 18 antifoulings after 24 months in the water, and rate the top specialty antifoulings in specific niches, such as eco-friendly bottom paints, aluminum-safe paints, race-ready antifoulings, fast-drying bottom paints, and budget bottom paints. The bottom paints were tested in both Florida and Connecticut waters. The manufacturers include Alwgrip, Blue Water, Epaint, Flexdel, Interlux, Pettit, and Sea Hawk. Some of the best bottom paints included Epaint EP-21, Pettit Hydrocoat, Epaint ZO, Blue Water Kolor, Interlux Fiberglass Bottomkote, and Sea Hawk Sharkskin.
