Testing Top-Down Furlers
Top-down furlers have proven to be a legitimate means of taking the drama out of spinnaker setting and dousing, and they represent a new breed of hardware thats carefully designed and manufactured to be durable for the long haul. In Part I (PS, January 2014) of this two-part report, we introduced five top-down furlers, detailed how they work, and made a good case for their use. In this article, Part 2 of the series, well take a closer at the furlers and the results of on-the-water and bench tests. Spinnaker furling systems we tested were made by Colligo, Karver, Profurl, Ronstan, and Selden.
Reader Experiences with Top-down Furlers
Following the publication of Part 1 of this report, we heard from several readers about their experiences with top-down furlers. Here are a few of their comments.
Anchor Rode Report
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.
Rodes Tested from Shore and Catamaran
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.
Mantus Upgrades to a Stronger Shank
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.
Spinnaker Furlers
The first in a two-part series, this article takes a look at the latest furling systems for nylon and other lightweight, off-the-wind sails dubbed A-sails, gennakers, asymmetric spinnakers, and other appellations referring to light-air, curved-luff sails. We compare the basic features of five systems: the Colligo CN3s; Selden GX15; Karver KSF2; Profurl Spinex 2.5; and Ronstan 120. In part two of the feature, we will report the test results and final ratings.
Boom Furler Test is Overdue
I was re-reading your review of in-boom furlers in which you compared five different manufacturers products. You did not review the unit made by Southern Spars, which is a spinoff of the Leisure Furl system by Forespar, but I wonder whether you have ever reviewed and compared the Southern Spars in-boom roller furling system?
Mantus Anchor-chain Hook
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.
LMs Quality Has Won Over Many European Fans
The LM32 construction is conventional but well done, and the boat lives up to its reputation for high-quality and fine craftsmanship.
Reversible Awning: Made in the Shade
While everyone likes fun in the sun, theres nothing better than having it made in the shade-which is a precious commodity aboard a sailboat. At anchor, over-the-boom awnings provide both direct protection from the sun and cabin cooling by shading the deck and cabintop, significantly reducing temperatures down below. Most canvas shops can design and create custom awnings for a boat, but this route can be pricey in some markets. For those wanting to keep their cool without hiring a custom designer, other options include devising a homemade setup for next to nothing, or searching out a quality, pre-fabricated sailboat awning like the UltraShade reversible sun shade.

Tartan 31 Piper: Used Boat Review
The Tartan 31 is one of the new line of performance cruising yachts from the venerable-and durable--Grand River, Ohio boatbuilder. In the last few years, Tartan Marine has come out with a range of new models, including the T-28, the 3500 and the 4600. A 41-footer is in the works. Both the 28 and the latest version of the 31 are part of the new Piper series, which are marketed in sailaway condition. Tartan has a reputation for solid construction and good workmanship and that's what the 31 is: solid and well put together. The hull is hand-laminated with alternating layers of chopped strand mat and unidirectional E glass. Behind the NPG/ISO gelcoat there's a layer of vinylester resin, which so far appears to provide the best osmotic blister protection available.
