Testing a Dynamic Traveler

Sailors gaze longingly at the rope wall at the local chandlery, coveting rope made from exotic fibers that promises ultra-low stretch and light weight, perfect for every halyard, sheet, and running-rigging application. But are they really? Certainly, there must be applications where a little stretch is a good thing, perhaps the best thing.

Refining Furling Line Fairleads

There was a time when headsail handling meant snapping on bronze piston-hanks and hauling on a smooth-running halyard. Times have changed, and now its all about how the furling drum rotates and the headsail wraps around a foil-covered headstay or freewheeling torque rope. (See PS August 2009 for our in-depth jib furler comparison.) Some systems behave more willingly than others, but all benefit from low-friction leads guiding the furling line back to the cockpit. The following report takes a close look at how these fairleads stack up and how much efficiency they add to the furling process.

Untangling Furling-line Fairlead Logistics

Headsail furling on sailboats 40 feet and shorter should be able to be accomplished with a hand-over-hand pull on the furling line. If a large genoa is set and the breeze fills in abruptly, it may take a little coaxing with a winch to get things going, but when its a fairly light-wind day and you need to start cranking away on a primary winch to instigate the furl, something is wrong with the system.

Going Soft on Shackles

Fiber shackles have been in use for centuries-the simple knotted toggles provided all manner of service on square-riggers and even older craft. When made correctly with the right material, fiber shackles are strong, can be released without tools, and are jam-proof in the most severe weather. Like cotton sails, this 200-year-old technology has been updated through the use of modern materials.

UV, Chafe Protection

Last fall, we reported on how to build strong, hand-stitched eyes in the ends of a rope, a skill particularly useful for older halyards and sheets that are too stiff for a typical bury splice (see PS October 2014 online). We also warned against the ravages of ultraviolet rays (UV) and chafe on the stitching, since so much of the strength lies vulnerable on the surface. In this report, we look at means of protecting stitched splices from UV and chafe.

Abrasion and Break Testing

Testers first task was to determine whether any of these coatings could weaken line in the near term. To do this, we formed 20-inch loops of 1/8-inch polyester braid and nylon braid, coated a 1-inch length of the loop with each of the products, and broke these in our test rig.

Survey: Mainsail Track Hardware

Its been almost 10 years since Practical Sailor weighed in specifically on mainsail track hardware. (See Practical Sailor, Feb. 1, 2005 online) At the time, we offered a summary of the products designed to manage what we termed the three Ss of mainsail handling-setting, shortening, and striking. In that article, we focused on the gear used with full-battened mainsails, which were becoming increasingly popular among a broad spectrum of sailboat owners then.

Top Whipping Twines

The term whipping twine is somewhat misleading, suggesting a single purpose for a product with seemingly endless uses. These are the thin-woven strands that all hand-sewing projects depend upon, and in the process of exploring various stitching projects, weve gone through spools and spools of it.

Rope Clutches Tighten Their Grip

Like the character Jaws in the old James Bond movie, rope clutches grab hold with a ferocious bite. This month we take another look at these toothy devices and how changes in materials and design are reshaping the art of clamping down. Since our last test (see Practical Sailor March 2009 online), several manufacturers have improved their existing designs to grip better than ever. Others have unveiled completely new approaches.

Higher Loads Call for Careful Installation

Rope clutches are a great innovation that can help sailors better control the lines that lead aft to the cockpit and those that cluster around the mast base. But as with many good things, there is the risk of over-doing the benefit.

Winterizing Your Boat’s Water System

Much of your winterizing success will depend on the initial condition of your existing water system. If it is nearly sterile (effectively chlorinated water), there may be too few bacteria and fungus present for infection to start. However, if you use less than 20 percent alcohol or glycol (after dilution with water left in the system) you are at risk of biological growth; the lower the concentration the greater the risk. This is the reason why vodka and other alcohol-based winterizing fluids should be avoided. In our testing these solutions acted like an invitation to a microbial feast.
