Switching to small-diameter, high-tensile chain (G70 or greater) leads to a hunt for small shackle pins to fit the chain’s smaller-diameter openings without weakening the rode. A small-diameter, high-tensile pin joins two U-shaped parts in a hammerlink (at left). Some sailors use omega links (at right) like these 6-mm Excel omega links from Van Beest (pictured with G80 chain). The yellow omega connector shows an assembly with a very short clevis pin (centering load). The identical, grey omegas were both Armorgalv-coated; the one on the left was tested to failure. The bow opened slightly, allowing the pin to be released and sheared. (Photo/ Jonathan Neeves)

Anchor Shackles: The $15 Insurance Policy

Were always amazed how a sailor can spend months agonizing and wringing his hands over which anchor to purchase, and then, when he finally shells out $700 or much more for the anchor, hell attach it to a shackle that has no business being on a boat. Weve plowed through the topic of shackles in several recent issues, but we havent looked specifically at anchor shackles for more than a decade. Choosing a properly sized, high-quality shackle is important, but its also essential to be familiar with proper use.

Making Sense of Marine Chain Standards

Chain is made from wire. The cross-sectional area and strength of the wire determines the strength of the chain. The weld of each link should be stronger than the wire, so if a chain breaks, it should break in the body (wire)-usually at the crown, or the curve in the link-not the weld.
Ultra claims its ball-and-socket swivel (top) is stronger than the chain it is meant to pair with, even when side-loaded, so attaching it directly to the anchor is no problem. Nevertheless, it’s obvious how the forks on a streamlined, jaw-and-jaw barrel swivel could pry open as side-loading increases. We saw evidence of this in our samples.

Anchor Swivels: Caution Required

Stroll down the docks at any boat show, and youll see a surprising number of boats equipped with expensive, stainless-steel swivels between the anchor and the chain. Almost all of these swivels are highly polished, machined and/or welded gems that cost anywhere from $80 to $200 or more. By comparison, a galvanized anchor shackle rated to withstand the same or greater loads as the chain rode we rely on costs less than $15.

Anchor Snubber Shock Load Test

In the past, a snubber was simply a device incorporated into the anchor rode to take the load off the windlass. We recently tested different types of snubber material, including nylon octoplait, rock-climbing rope, and rubber. Our tests were conducted as part of a long-term project on anchor-snubber selection, deployment, and care. Although there are some pre-fabricated snubbers on the market, most cruisers make their own, so this initial comparison was more generic in scope, focusing on common materials and designs.
Anchor chocks hold an anchor securely on any reasonably flat surface, but you’ll need to drill 10 holes to mount the component parts, so think twice about this option. (Photo and line drawing courtesy of Sea-Dog)

Advice on Buying a Pre-Owned Anchor

Since defects are usually obvious, anchors is one category of gear in which “what you see is what you get.” Certainly, there are counterfeits and home-welded one-offs that you’ll want to avoid, but the fakes and do-it-yourself anchors are usually easy to distinguish. Before you buy a used anchor, you should have a very clear picture of the size, type, and brand of anchor will best suit your needs. Depending on the specific anchor you seek, you can save 30 to 50-percent on cost by purchasing a pre-owned anchor instead of a new one.

Superlight Anchors: Not Just for Racers

The anchors a sailor chooses to carry onboard are often a compromise between weight and necessity. Since different anchor types are designed to work best in different conditions, it is a good idea to carry several anchors of different designs. So where does a lightweight alloy anchor fit in the hierarchy of cruising anchors? Practical Sailor looked at the weight, performance, design, and price of lightweight, alloy anchors from Spade, Fortress, Manson, and Anchor Right.
