Each manufacturer offers specific guidance for terminal assembly, and some do a better job than others. The following is a generic description of the assembly process using a Norseman fitting as an example. The other two fittings in our comparison, the Sta-Lok and the Hi-Mod, incorporate a third component, a crown that helps guide and hold the wire strands in place.
A couple of months ago, PS Technical Editor Ralph Naranjo disassembled a headstay that he had used aboard his Ericson 41 sloop, Wind Shadow, for nearly a decade. It was set up with Norseman fittings as terminals for 3/8-inch diameter, 1x19 stainless-steel wire that had supported a Harken roller-furling system. During disassembly, neither the wire nor the end fittings showed signs of corrosion or physical wear. And when the fittings themselves were taken apart-requiring heat to free the sealant in the terminal-the wire bundle was pristine and showed no sign of any slippage or corrosion.
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.
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.
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.
For decades, adjusting the genoa sheet leads from the cockpit was a luxury ascribed to racing sailboats. But todays cruising sailboat equipped with a roller-furling headsail also benefits from an efficient, safe means of adjusting the genoa sheets lead angle. We tested 11 genoa sheet-lead cars and tracks from the top manufacturers of sailboat deck hardware: Antal, Garhauer, Harken, Nautos, Ronstan, Schaefer, and Selden. Testers looked at the genoa-sheet controls operational efficiency, design and attributes, construction quality, and ease of installation; price and warranty were also considered.
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 few issues ago, you had a short article on deck hardware (blocks, traveler, cars, etc.) that included Garhauer, and you mentioned that the manufacturer offered individual parts and complete systems that allow conversion from on deck to cockpit adjustment of the car position. We recently installed the EZ adjustable genoa car system from Garhauer and are very pleased with the results. This equipment fits on existing traveler tracks, is easy to install, and performs as advertised.
Titanium’s high price is only one thing that is keeping in the realm of mega-yachts and Cup boats. Some of the essential roles that lightweight metals once played in deck hardware are now being taken by high tech fibers like Spectra or Vectran. Carbon fiber laminates are also taking the place of metal fittings, at a slightly lower cost. Nevertheless many manufacturers see a bright future for titanium. Here is some feedback we got from manufacturers on this topic.
Stainless steel is exactly what the name says; the steel “stains less.” As PS’s February 2007 special report “Marine Metals Warning,” pointed out, stainless steel is not the maintenance free miracle material many boat owners imagine it to be. Some stainless steel is more stainless than others. With over 500 different grades of stainless steel, only a few meet the mark for use in the corrosive marine environment. Most marine stainless steel is grade 304 or 316. Stainless steels are made up of metals with a blend of iron, chromium, and nickel. Chromium resists corrosion, and nickel resists acids.
