The Ultimate Test Boat Test

January 3, 2017 - I’ve been the fortunate witness to the rebirth of a boat and the marvelous effects that sailing can have in the life of a boy. And Practical Sailor readers have unknowingly been along for the ride. For the past five years, boatbuilder Robert Helmick has allowed his Endeavour 42 Lost Boys to serve as a test platform for a wide array of sailing gear featured in these pages.

Can a Snubber Hook Weaken Your Rode?

December 25, 2016 - In the March 2016 article “Changing views on chain hooks,” we pointed out that the major manufacturers of marine anchor chains caution that some chain hooks can weaken chains under extreme loads. These chain hooks are often used to attach an anchor snubber to the anchor chain. We confirmed this effect with testing and advised that if you want to use a hook on your anchor snubber, you should choose a hook that doesn’t weaken the chain through point-loading (concentrating shock loads on a small area of the chain link). Greg Kutsen, president of Mantus, the maker of one of the chain hooks that we tested, contends that the real-life loads encountered when anchoring with a snubber are not significant enough to worry about any point-loading caused by the hook on the chain. Kutsen explains the reasons for his view here.

The Chilling Facts About Cold Water Survival

December 21, 2016 - After living in Florida for so many years, it is easy to forget the risks associated with colder waters, as the video on cold-water survival that I have included in this week’s blog post demonstrates. According to the U.S. Coast Guard, the risk of drowning increases nearly five times if the water temperature is below 59 degrees. That puts many sailors in the Northeast, West Coast, and Great Lakes areas at risk for most, if not all of the year.

Storage Tips for Gasoline and Diesel

December 14, 2016 - If you're putting your boat into storage this winter, one of the simplest jobs you can do to save you headaches next spring is to make sure you’ve treated your fuel system for storage. For owners of diesel engines, you want to protect your tank year-round against biological growth—primarily fungus and bacteria. For owners of gasoline powered boats—the bad side effects of ethanol fuel are your chief enemy. Our test of biocide treatments safe for diesel fuel singled out products from Biobor, Racor, Starbrite, and Valvtect as good choices. For those with gasoline engines, the problems with ethanol require a specialized product. This month’s issue has an update on our test of ethanol fuel additives for marine engines. BioborEB again proved its superior ability to fight corrosion. Sta-Bil Marine Formula, Star Tron, and Mercury QuikStor (the most expensive treatment, by far) picked up recommendations. Sea Foam came in as the low-budget contender.

Dealing with Dirty Sails

December 6, 2016 - For washing your sails, most sailmakers recommend using mild soap and water, and avoiding anything abrasive. Use a soft brush, if necessary, to loosen dirt. For dirt or stains that are more deeply embedded, you may need to soak the sail, so you'll have to locate some kind of large container, depending upon the size of the soiled area.

Don't Let Refit Pitfalls Derail Your Cruising Plans

November 29, 2016 - As a good friend finds himself in the middle of the often daunting process of equipping a full-size cruising boat for an extended cruise with his family, I found myself reflecting on some of the things I discovered over the years through my own experience and the experience of others. There seems to be no shortage of books that tell you what you need to do to go cruising, but very few seem to caution about what NOT to do or what to avoid. Here are a few things that I found get in the way of a long-term sailing escape. I’d love to hear more tips on how to avoid these and other pitfalls that can swallow the cruising dream.

Can You Have Too Many Zincs?

November 23, 2016 - Although it is unlikely in a typical installation, you can have too much anodic protection. This is more common with miscalibrated impressed current systems, where a transformer is used to provide the electrical potential, but too many zinc anodes or too reactive anodes can also have unintended consequences you should recognize. This is particularly important for owners of wood or steel boats.

Corrosion Protection: Ethanol Fuel Additive Test

November 16, 2016 - Those boatowners preparing their gasoline-powered boats for winter storage will want to take a look at our gas additive test which compares the corrosion fight characteristics of such products as Biobor EB, Valv Tect, Sta-bil Marine Formula, Mercury QuickStor, Sea Foam and others. It is important to keep in mind that additives can’t solve real gasoline-quality problems. At best, consider additives to be only a final tweaking opportunity, something to supplement the following fuel-management practices.

Tips for Caulking Polyethylene

October 26, 2016 - In our upcoming test of marine sealants we looked at ways to develop bonds between common polyurethane sealants and polyethylene plastics—the kind of plastic used in a variety of marine products ranging from fuel tanks to baseplates. Starboard is one of the most common brand-name high-density polyethylene materials, and it is notoriously difficult to seal or bond using conventional caulks or adhesive sealants. But there is a partial solution to using an adhesive sealant with plastic, and our tests show it works.

The Blow-by-blow Boathook Test

October 11, 2016 - Our first surprises came when we began pull- and push-testing the telescoping boathooks. Only one pole consistently held firm under load. All the others slipped at loads between 100 and 185 pounds. We then tested them in compression. Most of the poles could manage 170-pounds of compression, although a few telescoping poles slipped.

Is Stainless Steel Really the Best Metal for Use in an Anchor?

September 27, 2016 - Each time Practical Sailor conducts an anchor test, we get questions about the materials used in anchors, particularly stainless steel. Stainless steel is much less prone to unsightly and destructive oxidation than mild steel, even when it has been hot-dipped galvanized and protected by a heat-bonded zinc coating.

Tips on Choosing and Sizing Anchor Shackles

September 21, 2016 - In the most recent issue of Practical Sailor, we identified four anchor shackles that fell below expectations and are advising readers not to buy these shackles. Two of the shackles were stainless steel, a material we regard as unsuitable for use as an anchor shackle, and two were galvanized shackles distributed widely in the United States and abroad.

Tips on Caring for Marine Canvas

September 13, 2016 - Canvas dodgers and biminis are the hallmark of a cruising yacht, keeping the sun at bay and allowing the crew to “dodge” the worst of the weather. On board, canvas also protects sails, windows, and machinery. Collectively, these represent a substantial financial investment, and we wanted to find the best way to protect the investment and get the most life out of the canvas.

A Simplified Internet Connection for Boats

September 7, 2016 - As high-speed, cellular data service extends throughout the coastal U.S. and abroad, the ability to turn your phone into a mobile hotspot (MiFi) has diminished the need for a Wi-Fi connection to a shore-based network. But cellular data plans can be expensive, service can be spotty, and high-speed data isn’t offered everywhere. In the October 2016 issue of Practical Sailor we look at an integrated antenna/WiFi adapter/router that allows you to quickly connect to the internet using either a shore-based Wi-Fi network or cellular service (2G/3G/4G/LTE).

Preventing Fuel Problems in Marine Diesel Engines

August 19, 2016 - Murphy’s Law has an affinity for old marine diesel engines with aging fuel systems. Contaminated fuel is a common problem, and late last year we looked at various additives that claim to preserve stability in both gasoline and diesel fuel during long-term storage. But fuel system maintenance doesn’t stop during the sailing season. Here are some fuel-system management practices that will help you avoid any fuel-related problems this season.
