Circle 87 on Reader Service Card American Vulkan Shafts Help Improve Performance Composite Shafts from American Vulkan can help to improve vessel per- formance in terms of fuel consumption, maintenance cost, lower weight, reduced noise and vibration and fewer shaftline bearings. The Applied Com- posites shafting system gives a new per- spective to lightweight composite shafts. Due to the high stiffness and vibration-absorbing properties of the material, carbon-fiber shafts have a higher critical speed than shafts made of steel or light metal. This allows the operator to save on weight and fuel while enhancing performance.
