SCR Airfoil

The first and only carbon rigging with an airfoil shape. SCR Airfoil is the next generation of Hall's successful Seamless Carbon Rigging, designed specifically for aggressive programs looking for the maximum speed edge.

The streamlined shape of SCR Airfoil reduces frontal area, and therefore windage, by up to 50% over other rigging products. Since standing rigging is the main source of rig windage, this reduction will give any boat a quantifiable improvement in speed.

"At Hall, we're obsessed with windage reduction," says Eric Hall. "With SCR Airfoil we've taken windage reduction in rigging to its limit. It will be hard to beat," says Hall.

Advantages

Windage Reduced to Bare Minimum
Airfoil shape reduces frontal area up to 50% over other composite products.

Unmatched Longevity
SCR Airfoil is made with the same carbon and thermoset resins as our masts. It will not degrade in strength over its lifetime and potentially needs no replacement unless actively damaged.

Proven Design
Shaped rigging is not new; what's new is Hall's ability to create a streamlined shape in carbon fiber. Shaped rigging first appeared in racing aircraft in the 1930s. It had a lenticular, or elongated oval shape and was created by machining stainless steel. Eric and Ben Hall's father, Bob, used lenticular rigging on racing aircraft of his own design. In the 1970s the 12-Meter Intrepid used lenticular standing rigging; Eric Hall was project manager for Intrepid. But the weight, and expense, of creating these machined shapes put shaped rigging on the back burner. Until now.

Components

 

 

Solid Carbon Construction
SCR Airfoil is solid carbon, not bundled rods. Solid construction eliminates the air trapped between the small pultruded elements (such as C-6) or yarns (PBO) and SCR does not require a braided external sheath. Solid rod also means no moisture issues.

Low Windage 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
Using a discontinuous set up and separating the elements, Hall reduces interference drag at the spreader tips. For economic reasons and maximum service life, Hall recommends discontinuous systems for SCR. If an element is damaged, only that elements needs replacing, saving the time and expense of replacing an entire side of continuous rigging.
