Aluminum vs Carbon Booms
March 21, 2011
We discuss the merits of aluminum vs carbon booms everyday with our customers and have always wanted a way to show people how big the difference in stiffness is. These GoPro action videos show very clearly the difference in deflection of carbon vs aluminum booms. The aluminum boom is a full monocoque aluminum boom with 29mm grip from HPL and the carbon boom is a Streamlined 100% prepreg carbon boom. Whena boom flexes, the clew length changes, forcing the draft to move back and forth as the amount of flex is varying continuously. A carbon boom has dramatically less flex, delivering more stable and comfortable power delivery and making your rig far easier to manage particularly in overpowering conditions. Get in touch with us at 1-800-473-1153 to learn the details of all our boom offerings or check them out at isthmussailboards.com.
