Anchoring Mooring

In recent years, our chain tests (see PS September 2006, July 2007, July 2008, and October 2012 online) were limited to G30 and G43 (high-test) chain. Our conclusions were pretty straightforward: We would avoid stainless steel for several reasons, the most persuasive being its tendency to fail without warning-as our test sample did. Recognizing that corrosion is what ends the life of most chains, we were not convinced that shelling out more money for the extra strength of G43 chain made sense. It lasted no longer than G30.

The value of catenary varies with the depth of the water. In shallower waters, bottom friction replaces gravity as a force of resistance against shock loading.

Every decade or so, local sailing clubs go through a re-evaluation of their mooring fields, looking for ways to improve or upgrade equipment without straining their budget. Island Mooring Supplies, the same Rhode Island-based company that introduced the splinter-free Deluxe Pickup Stick we featured in the April 2010 issue, has developed a new, soft mooring buoy designed to put an end to the annoying hull-knocking of conventional mooring buoys.

After nearly four decades of being married to my CQR plow anchor, I decided to try a new anchoring solution aboard my Ericson 41, Wind Shadow, and mounted a Manson Supreme on her bow roller. Ill be long-term testing the Manson, but heres a preliminary look at the CQR and the Manson.

In our continuous research of ground tackle, we noticed that large oil rigs are often anchored into place with a spider web of stranded wire-or in some cases, Dyneema, a low-stretch, high-strength synthetic fiber. We wondered whether Dyneema or a wire cable might have some application in recreational sailboat anchoring, and we launched field tests to find out. These tests also looked at how changing the diameter of your anchor chain affects anchor performance.

Our test anchors included a small, 11-pound Spade anchor, which we set using a chain winch off a beach in Pittwater, Australia. We set the anchors using two different rodes: 30 feet of 5/32-inch stainless wire strop that we fabricated using old lifelines and 33 feet of quarter-inch, short-link BBB chain. We extended each rode with 5/16-inch chain and aimed for length-to-depth ratio of a 5-to-1.

Late last year, we had our first look at the bolt-together Mantus anchor. Although we liked the design, and prices were favorable (around $330 for a 35-pounder), we raised concerns about the shank strength, which by our estimation was the weakest of all anchors of a similar design.

Practical Sailor recently looked at various ways to take the load off the windlass and roller by means of a short rope snubber or bridle, but we did not talk about how to attach a snubber to the chain. The Mantus Chain Hook takes an innovative approach, and seemed particularly useful for catamaran owners with long bridles. Testers put the 1/4-inch stainless Mantus hook through more than 50 anchoring cycles and dozens of tide cycles aboard a PDQ 32. Find out how the Mantus fared.

Alpenglow I would like to take this opportunity to express my gratitude to (and recommendation of) the folks at Alpenglow Lights (www.alpenglowlights.com). We have many of their fixtures and have contacted the company on numerous occasions for new sales, upgrades, and technical questions. Without fail, they have exceeded our expectations, from offering to perform upgrades at minimal cost, to telling us secret workarounds that enabled us to use locally sourced parts and supplies to re-invigorate their excellent lighting units.

A photographer friend stumbled upon this photo of my wife, Theresa, from our cruising days. It was taken in Fiji around 1995. She doesn't usually look this serious; it probably had something to do with having two guests on board a cramped 32-foot Atkin ketch for a couple of weeks. I thought the image illustrated well something that Ive been thinking about lately: the value of resourcefulness while cruising. This notion of the self-sufficient sailor came to mind most recently while watching the movie trailer for All is Lost, in which a single-handed sailor (played by Robert Redford) tries to keep his beloved Cal 29 afloat.
