Interesting thread, My boom is my only piece of kit that isn't high tech. Mark's comment about the sail bagging more when a gust hits has me thinking I might need to upgrade. The only time I've had an alloy boom break was when I let Waiting4Wind test drive one of my sails, and him being considerably heavier than me, he was under-powered and had to pump rather vigorously to get on the plane. The following day, it snapped while rigging up.
I think it's a size thing .
If your 70 kg and only riding 5 m max ,a good alloy should be just fine .
If your above average heft , blasting over 7 m , carbon is your friend ,
I am over average sexuality and have wreaked 3 alloys and no carbons , and I'm still trying .
