Sails, Rigging & Deck Gear

Stroll through your local marina, and youll likely see plenty of resurrected, vintage sailboats sporting fresh paint and new rigging, but all too often, antique mainsheet blocks have somehow escaped the upgrade. Part of the reason for this oversight is that the sheaves get only an occasional, no-load test spin, and all but the most severely deteriorated pass the scrutiny. A mainsheet tackle upgrade can be a relatively inexpensive investment that pays high dividends in improved sail efficiency. Practical Sailor tested eight 4:1 mainsheet tackle systems sized for 20- to 30-foot sailboats to find out which is the best. The test field included fiddle blocks and fiddle blocks with cams from Antal, Garhauer, Harken, Ronstan, and Selden.

The string of anchor tests weve carried out in the last year presented a good opportunity for us to also test an anchor accessory: the Shockles anchor snubber. Makers claim it helps your anchor stay set by reducing the constant shock loads during strong winds or in rough seas. We did some real-world testing aboard a 6-ton Lightwave 38 catamaran in a range of conditions and anchorages, and we also bench-tested the snubber, using a load cell and chain winch.

Summers warm breezes and lazy weekends have arrived, so PS testers have put together a lineup of cool toys and tools for the dog days. Tower Adventurer Inflatable Standup Paddleboard: Inflatable SUPs are sprouting up everywhere on the Internet; many boards are identical, made by different brands at the same factories in China. Quality varies. Generally, boards 6 inches or thicker offer better stiffness and stability, making them easier to ride.

How thick is too thick for the buildup of old layers of bottom paint? This question arises because I have just finished painting the bottom of my boat. Even though I diligently sought out potential flaking spots with my knife, while rolling on the paint (Pettit Ultima Eco), I would frequently get a mess caused by the paint flaking off. I have only owned this boat for three years, so I really do not know how many layers there are.

In the first part of this series on anchor-shank strength, we examined how the shanks of anchors that supposedly met the most stringent industry standards could bend under loads that a typical cruising sailboat could encounter. With this installment, we wanted to demonstrate how that might happen in a fact-finding field test. Based on our previous findings, we concentrated our study on a specific group of anchors and specific type of load. The anchors are regarded as super high holding power (SHHP) anchors, and the load was a sudden, snatch (or dynamic) load applied at a 90-degree angle to the direction each anchor was set.

As more and more anchor-makers source their materials and move their fabricating offshore, Practical Sailor has been fielding an increasing number of questions about anchor quality. Is the tensile-strength steel used to fabricate anchors consistent with the application? Is anyone actually measuring shank strength? And how much does it matter? At the heart of this discussion is shank strength. There seems little point in having a high holding-capacity anchor, if the shank isn't strong enough to cope with projected loads.

Anchor testing at Practical Sailor has always been a controversial enterprise, sure to fire up someone. As one reader commented in response our most recent anchor report (PS, March 2013): Anchors are a whole lot like religion. No matter what the tests show, each of us has a favorite that well defend to the death! This month, our report on anchor-shank strength approaches the topic from a different angle. Rather than singling out specific anchors for holding power or design, we take a closer look at the way anchors are evaluated and promoted.

Taking the advice of a PS review, I installed a Lewmar V2 windlass on my boat in 2008. I went with the installers recommendation of 100 feet of galvanized chain and 100 feet of eight-part braid, connected with a rope-to-chain splice, and I have a Delta 35 anchor. I found that a chain hockle (a twist in the chain that jams the windlass) will terribly mangle the vertical windlass. I have just completed my second mangling and ordered replacement parts-but these parts will not save me from the next mangling. The Lewmar distributor told me to install a chain swivel, but PS has warned about this (PS Advisor, May 2010). Is an all-chain rode a dumb idea? Is there some solution?

Practical Sailor has carried out dozens of anchor tests over the years. This month, we set out to compare anchor performance when the boat position changes under the forces of wind or tide, a shift that often causes the anchor to move and reset itself. The test compares 12 anchors, including some newer fixed-shank anchors-such as the Rocna and the Manson Supreme-and some concave fluke designs similar to the Spade, one of the strongest performers past tests. The test field included: the CQR, Spade, Ultra, Super SARCA and SARCA Excel, Manson Supreme, Rocna, Kobra, and the Lewmar Claw.

For 20-plus years, I have removed my mooring buoy from the water at the end of the sailing season on Lake Champlain. This year, however, I was surprised to find that my mooring chain was totally covered by zebra mussels. The 3/8-inch chain was about 3 inches thick with mussels when I hauled it up! Do the zebra mussels affect the chain strength or its life expectancy?
