I should clearify this. I was told the US prototype still used the old Rig (Dan ?). I didn't mean to say that the production US boats would maitain the older mast section. I fully expect all to be fitted with the wingmasts from Europe.

I can't give any judgement before I test sailed her, but if the new wingmast on the nacra is anything like the Superwing I have on my own boat then this is going to be a major selling point of the Nacra infusion with respect to all others except the capricorn.

On one hand it will be more difficult, accurate trim is important for these masts, but on the other hand the sailors will appreciate its performance and handling. These masts talk to you. If you change some trim then the mast will often immediately give a change in feel. It will nearly always be (immediately) clear whether the change was a good one or a bad one. With this it is easier to experiment and find good trim. At least this is my experience with my own Superwing (wingmast) on my F16.

I hope this clearilfies things.
