The mast is 9,00 m long and the advertised weight is 100 kg.
I believe that the X-16 currently has an A class rig on it, which would explain why the height is what it is. It's understandable that a manufacturer will want to re-use existing components, but I hope that this is just a stepping stone to producing a fully compliant F16. I think the kite on the X-16 is significantly smaller than F16 allows, but even so the X-16 was already competitive at Carnac. Converting it to a fully compliant F16 would seem like a win-win situation, and should not be a great deal of work: the boat is already down to weight, and the platform is compliant.
