SCR

Hall Seamless Carbon Rigging is solid, not bundled, making it the smallest diameter composite rod for equal stretch on the market. Hall SCR has smaller end fittings than other composite rigging systems, too, making it more aerodynamic overall. Made from Titanium, Hall SCR end fittings are far smaller and lighter than anything in the composite rigging sphere.

Hall SCR is also proven on the racecourse. Ben Hall, sailing his Evelyn 32 Bluto with a full set of SCR rigging, was named Boat of the Week at Key West Race Week in 2010. "The best part was being competitive through a wider range of conditions," says Ben of sailing with SCR. "We could see that the mast stood up well while sailing upwind in waves. With the carbon rigging the mast just doesn't move around," says Ben.

"It also helps that the mast and rigging are much lighter. The mast doesn't pump like it used to, even without the checkstays." (Bluto was originally equipped with an aluminum mast with wire shrouds and checkstays. With the switch to carbon, the checkstays were eliminated.) We noticed we were pitching less and we were pretty quick upwind. Bottom line is, with SCR rigging the boat is livelier and even more fun to sail.

Advantages

Significant Reduction in Windage
The small diameter of the solid rod means less rig drag, which translates into more speed and less heeling moment. On average, SCR has 15% less windage than either PBO or bundled carbon products.

GL Approved
SCR passed an exhaustive series of 16 tests to achieve type approval from Germanischer Lloyd. While there are strict confidentiality limits on releasing results of the GL testing, we can confirm that tensile, fatigue, impact, and chafe tests were all part of the process and SCR solid rod passed with flying colors.

Unmatched Longevity
Hall Seamless carbon masts have a safety record unmatched in the industry and our Seamless Carbon Rigging is made using the same carbon and theromset resins used in our masts. SCR is one seamless piece, eliminating the guesswork involved when inspecting PBO fiber or carbon bundles hidden under a braided cover. We can state that SCR does not degrade in strength over its lifetime. Our product potentially requires no replacement unless actively damaged.

Award-Winning Design
The DAME Awards are an annual event recognizing new and innovative products in the marine market. There were 125 entries from 21 countries in the 2009 contest. SCR was the winner in the category Deck Equipment, Sails, and Rigging, which was also the largest category. The DAME jury described SCR's end fittings as "superbly designed" and the press release stated that "The jury liked the sleekness and simplicity of the design and the ease of installation."

Patent-Pending End Fittings
SCR uses a breakthrough, patent-pending end fitting attachment system, allowing much smaller end fittings and thus smaller, lighter mast attachment tangs. Every SCR end fitting is made from titanium. Our unique end-fitting system allows us to attach stemball ends almost identical in size to Nitronic 50 equivalents yet achieve breaking strengths that are 50% higher.

Components

Solid Carbon Construction
SCR rod is solid, not bundled. Solid construction eliminates the air trapped between the small pultruded elements (such as C-6) or yarns (PBO) and does not require a braided external sheath. Solid rod also means no moisture issues. The product, though stiff, can be readily and reliably coiled to diameters somewhat smaller than those specified as minimum for Nitronic 50 rod.

Titanium End Fittings
We've designed new end fittings that constitute a quantum jump in reducing windage and weight. Made from Titanium, they are far smaller and lighter than the fittings on other composite systems.

Discontinuous Set Up
Hall SCR is available as discontinuous rigging only. Discontinuous rigging spares you the expense of replacing the entire shroud configuration (as required with a continuous set up) in the unlikely event of an accident. It also allows us to open the space between the vertical and diagonal on the spreader; a set up that is more aerodynamically advantageous than placing them close together. This configuration can only be achieved with discontinuous rigging.
