Sails Canvas

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.

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.

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.

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.

I am currently working with sailmaker Carol Hasse (www.porttownsendsails.com) on a new set of primary sails. She is the best at making cruising sails, and it is a luxury I am surrendering to. However, that is why I’m considering a DIY project for the trysail track. Any input on details such as proper track size, length, placement, and preferred mast fasteners and track backing (to combat corrosion) would be helpful.

In some ways, the good old days just weren’t that good. Just ask any old salt who has watched an expensive canvas dodger mildew, rot, and fall to pieces. When Sunbrella entered the market four decades ago, the strides forward were significant. When it comes to fabricating a long-term, waterproof fabric cover, it’s hard to beat the combination of vinyl and acrylic or vinyl and polyester. Practical Sailor compared Sunbrella, Sunbrella Plus, and WeatherMax in a long-term field test and some creative bench tests. Testers compared weight, sewability, breaking strength, water shedding, permeability, and price.

Two years ago, we sewed up our own dodger and assorted deck covers made from Sunbrella and WeatherMax fabrics and monitored how well the materials stood up to 24/7 weather exposure and the extreme climate flip-flops of the mid-Atlantic region. On a parallel track, we did some controlled—and creative—material testing restricted by tight budget constraints. For example, we lacked an Instron tension test machine to carry out a formal ASTN D5034 elongation and breaking strength test, so we did the next best thing: We made our own.

To keep your Biminis, dodgers, and sail covers clean and in service for the long haul, regular maintenance is a must. Here are some best practices and care tips weve picked up over the years.

One of the themes seen among the new entries is a trend toward thermal-setting rather than thermal-fixing plastic construction. The latter is representative of the most common approach to fiber-reinforced plastic (FRP) boatbuilding. A process in which room-temperature liquid-resin systems are used to wet-out reinforcing filaments in what has become generically referred to as fiberglass boatbuilding.

As with any big ticket item, choosing a new mainsail involves a number of choices, each of which are driven by an equally diverse list of factors to consider, from the type of boat (cruising, racing sailboat), and area sailed (inshore waters, coastal waters, or bluewater), to the type of sailor you are (performance-oriented hard charger or weekend warrior). Practical Sailor offers a step-by-step rundown of the available options and the selection process our testers experienced when we shopped for a new mainsail for our Chesapeake Bay test boat. While the decisions will vary, the exercise can serve as a template for any sailor looking to upgrade a mainsail.
