Hakan,
... are you really sorry about the M20 weight!? ...
I'm sorry about the fact that I had to inform you that the 120 kg were for the bare M20 (production version) and not for the upgraded sloop rigged M20's that are now sailing in NL. I got the impression that you thought the 120 kg ready to sail weight was for the modified boats, when it really wasn't.
I do think it a pitty that the M20 couldn't remain at roughly 110 kg or so. Lets face it, that would have been a very cool thing, no matter how one looks at it.
I think we have the answer to the question here. If you want a 20x10 uni rigged boat with spi it is hard to get below 100kg. Marstrom started at 108 kg but 15 boats later the boat weights 120 kg. Why? The parts that have been reinforced on the M20 are rudders and centerboards.
The rest of the weight increase is a mystery to me!
Well, if was only my job at the time to validate the overall weight measurement so that it was far too all parties. The hard numbers were in front of my eyes, but I will not disclose them here publically. I can tell that 120 kg was a good average.
I have not researched where the increases in weight came from. I don't really know where how the boat went from 108 kg to 120 kg. Or why it went on to 127 kg since 2003. I would like to know though.
I do think that the carbon rigging was replaced by steel, stuff like that.
Best of winds,
Wouter
