Boat Maintenance

Practical Sailor had a chance to compare how three common snap hooks and three tether types function in actual use on a passage from Boston to Bermuda. Testers evaluated the pros and cons of elastic tethers and non-elastic tethers, double-legged tethers, single-leg tethers, the new Kong snap hooks, carabineer-style safety clips, and the Gibb-style clip. The Wichard elastic single-leg tether (nearly identical to our 2007 tether test favorite from West Marine, the West Marine 6-foot elastic tether with Wichards double-action hook at the deck end) was unanimously preferred over the non-elastic tether. Testers also preferred the Kong snap hooks over the others.

Practical Sailor closes in on its search for the best teak oil, best marine varnish, and best synthetic wood finish this month. Testers check in on the 53 coated wood panels on our test rack, which have been enduring the elements for six months. Testers rated the panels for single-season gloss and color retention and coating integrity. The test products included dozens of one-part varnishes, two-part varnishes, synthetic wood finishes and stains, spar varnishes, wood sealants and teak oils from makers like Interlux, Pettit, Epifanes, Le Tonkinois, Minwax, Ace Hardware, Star brite, and West Marine. The long-term evaluation aims to find the best exterior wood finish based on overall ratings for ease of application, gloss integrity and appearance, and how the coating fares over time under real-world conditions. At the six-month mark, this report offers our single-season recommendations for finishing teak decks, cockpit trim, toerails, and other exterior wood surfaces.

In light of your recent letters on copper/epoxy antifouling bottom coatings, Id like to share my experience. Near the end of my Searunner trimaran boatbuilding project, I decided to apply a product known at the time as Copperpoxy. I applied the coating to all three hulls to about 20 mils thick, and then sanded this "orange peel" surface down to about 10 mils. I finished up with 220-grit sandpaper. In the end, it was beautiful. It was just like a perfectly smooth, new copper penny, and just a bit thicker than recommended. We started our cruising adventure in the foul waters of Beaufort, S.C. Very soon, I was doing a huge scrape job every week. The bottom was covered with grape-size barnacles. I noticed that the aft half of the main hull, the part with underwater metals, was fouling the worst. (I was changing zincs every week.) Two years later, in Pensacola, Fla., we decided to give up on this product and paint over it with Pettit Trinidad SR bottom paint. When doing the weeks-long prep for this painting, we could see that the skin of our epoxy/ply boat was electrically conductive and corroding all the way through in the entire area of the bonded shaft, strut, prop, gudgeons, and copper mast ground. We put on three coats of Trinidad, waited a few days, and splashed the boat. Within two weeks, the new paint had peeled off in the electrically active area. We re-hauled, stripped the paint in this area, and coated the problem Copperpoxy area with three coats of epoxy. After sanding and repainting, we set off for the Western Caribbean. Over the following six months, we noticed that even the epoxy would not stick to the Copperpoxy.

Practical Sailors May 2008 issue looked at green practices in marine maintenance outside the hull. This spring, we look at eco-friendly products and techniques for the boat interior. We focus on areas belowdecks where we can reduce our impact on the environment. Proper disposal of petrol fluids used in most inboard engines-fuel, lubricant oil, and transmission fluid-is paramount. Preventing engine fluid spills by using careful filling techniques is key, as are careful preparation for a possible spill and proper cleanup should a spill occur. The best products we found for preventing oil spills and cleaning up oil spills include 3M Sorbent Pads and MDR Oilzorb Engine Pads; Jabsco Oil-Changing System; and the Vetus Bilge Water/Oil Separator. We recommend RydLyme Marine and Barnacle Buster for a green descaling of a boats heat exchanger.Eco-friendly bilge cleaners that we recommend include CRC Industries Big Bully Natural Orange Bilge Cleaner, Clean Water Solutions Microbial Powder, Star brites Sea Safe Biodegradable Bilge Cleaner, and Star brites Super Orange Bilge Cleaner. Eco-friendly soaps and detergents recommended for green cleaning include Dr. Bronners Sal Suds and some cleaners in the Simple Green, Spray Nine, and Thetford Marine lines. And, don't forget plain old blue Windex.

Spring could not have come at a better time. Winters don't bring much drama here in Sarasota, Fla., but theres a chilly mood upon the land, and Ill be glad to finally be rid of it. Spring, no matter the latitude, brings with it new hope. There is nothing quite like the first breath of May in northland, when a grey fog gives way to warm sunshine, and the promise of June suddenly becomes real. I remember well spring in my former home state of Rhode Island-cherry blossoms, red-wing blackbirds, and the faint whiff of summer when we finally shook the tarp clear of our ODay Javelin, Misty. There is a reason why were alive, and spring reminds me of that. I don't pretend to know what it is, but Im sure of what its not. Its not to moan about missed chances, lament financial losses, or measure ourselves against marks set by other men. A sailor, above all others, knows that good fortune is like the wind. Todays warm westerly will be tomorrows noreaster, and we must make the best of each. I can curse the foul tide at the top of my voice, but that wont make it turn. Turn it will . . . but in its own good time.

Being able to communicate with a hands-free communication device along the length of the deck allows crew to coordinate activities like anchoring, docking, and going up the mast. Practical Sailor testers experimented with two systems: Motorola SX800R two-way radios and Nautic Devices Yapalong 3000. Both the Motorola and the Yapalong comprise a cell-phone-sized transmitter/radio unit and a separate handset. We tested them during anchoring, masthead repairs, and docking. The products were used with their mated headsets in various weather and sea conditions, including light rain and spray. The Motorola unit also was tested with a compatible Fire Fox Sportsman Throat Mic.

For those of us living, working, and playing on the water, rust can show up all too often, as the trailer for one of Practical Sailors test boats recently reminded us. Testers tried four aerosol products marketed as penetrating oils-WD-40, Liquid Wrench, PB Blaster, and CRC Freeze-Off-on the rusted U-bolts, and seized nuts and bolts of the neglected trailer to determine which is the best rust buster.

I read with interest your evaluation of first aid kits, which wrapped up with the final installment in the December 2008 issue. Id like to add a couple of points: Weekend, cruising, and bluewater sailors should invest in a good up-to-date first aid and CPR course. It is as important as a functional bilge pump. The responsible sailor can outfit a substantial and superior first-aid kit for much less money than a commercially available kit. The kit should be appropriate for the expected duration a victim will need treatment prior to evacuation. Most commercial kits contain a lot of fluff and are unnecessarily redundant-a lot of Band-Aids. I stress to distance sailors stocking a few prescription items and aggressive treatment for seasickness, beyond Bonine. I favor a solid medical text such as "A Comprehensive Guide to Marine Medicine," by Dr. Erick Weiss and Dr. Michael Jacobs, or "Medicine for Mountaineering and other Wilderness Activities," by James Wilkerson. The latter is available from Mountaineer Books. Both texts give guidance on stocking kits appropriate for your boat. Remember, the victim may be the captain or medical officer, and a novice may be the one rendering treatment. A medical guide is an invaluable resource.

While world leaders and presumed financial wizards set to work trying to right the global economy with some very expensive bailers and sponges, Practical Sailor has taken the time this month to dig through our recent collection of Chandlery submissions to see if we can find anything more useful. Given sailors capacities for innovation (aka "jury rigging"), were holding out hope that the next great invention-the ultimate stimulus package-lies somewhere in our growing stockpile of Chandlery items.

Over the years, Practical Sailor has tracked the evolution in marine antifouling paints. Shaped by government regulations, environmental concerns, and industry innovations, the shift started with tin-based paints in the 1980s. After tin-based paints came under fire for the harm they cause marine life, copper-based paints grew in popularity. Now, concerns about the impact of copper on the environment have led to the development of copper-alternative paints, such as zinc-biocide and water-based antifoulings. We continue to sort through the data to help you find the best bottom paint for your boat. This report offers an update to our panel tests after six months and 18 months in the water as well as the head-to-head tests under way on our test boat fleet. Some of the best performers (out of 72 paints tested) at six months were hard paints and specialty antifoulings such as Copper Shield 45 Hard made by Blue Water, VC Offshore by Interlux, Copper Guard by Pettit, and Sharkskin by Sea Hawk. The best ablative paints at six months included Copper Shield SCX 45 by Blue Water, EP-21 by Epaint, and Hydrocoat and Vivid Free by Pettit. The top long-term bottom paints-those appropriate for multi-season antifouling protection-included Interlux Micron 66, Pettit Trinidad SR, and Interlux Epoxycop. These extensive tests also included marine bottom paints from Awlgrip, Flexdel, and Microphase Coatings. The lineup also covered re-branded products from West Marine.
