Wouter: "Clearly Sarah has chosen the M18 as her next boat" well thats not really the case .. I must admit that the M18 is looking really good right now but im actually still considering the FX-one and maybe a Blade F16.
You might also consider the Shadow, its speed is about the same as an FX-One but with 95kg its considerably lighter (Good for righting).
