The M18 is a single handed boat and a wonder boat at that.
78 kg, 15sq M mainsail and 15 sq m Kite. The boat will rate somewhere around 0.9 on SCHRS - Tornado is 0.94 to give some idea of the potential speed of the M18 !!!!!!
If money were no object, then an M18 would be my next boat, however the price is looking at coming in at around 23500 Euro plus sails (last time I spoke to Goran Marstrom). Which is a lot of money, too much for me.
When I spoke to Goran he was very busy (had a few Carbon Tornado masts in production !), I'd expect he is a little less busy now and might have more time to discuss it.
