I disagree that ali is bad, I honestly don't know what you blokes do to them
As a 100kg guy sailing in 35kn 3 x a week and crashing bad I got 3 seasons from a Tecnolimitz Ergal boom. $500 boom.
ONLY changed it cos I felt like trying carbon.
Before that I had 3 seasons on a Chinook ally ($300 boom) and that was learning to wavesail at a hollow dumpy spot. I busted 3 masts and countess sails and that boom is still fine. Again, only changed it cos I had money burning a hole in my pocket.
Mark, I'm almost your weight, and I went through a few alu booms before I switched to carbon. I broke all of them at Safety Bay, just doing back and forward runs. I also broke a few sets of harness lines, so I think you could argue I am putting a lot of load through the boom/lines.
Maybe wave-sailing doesn't generate as much pressure on the booms?
Also, my aluminium booms had to cope with a range from 5.5m up to 8.5m, so maybe the change in length often, made the aluminium fatigue? My own pet theory is that if I used the same boom on almost the same boom length, it would last a lot longer.
