Wouter the prices for my aluminum is not only for the mast sections alone but for two runs of two different profiles of masts, two different boom prifiles )which are also mast sections but smaller) cross beams, tiller arms, tiller cross arms, spinnaker poles etc, and the weight that you are useing for an "average" mast is less than what the sections that I have been quoted on are. The billett that they run through the press is 1000kg, and the way that it is set up now is that I have to pay for a lot of their wastage. besides all that, the fact remains that, as a manufacturer I have always thoroughly sourced my costs very very thoroughly, (if I didn't I would go broke very quickly) as it is not only a passion for me (sailing) but it is also a lively hood for myself and my family, and the collective prices of aluminum that I would have to hold as stock makes it prohibitive to rely on aluminum unless there is a way to source material in smaller quantities at a reasonable price (as I said Capral have DOUBLED their prices at least THREE times in the last few years, and in the same time carbon has virtually HALVED)
