Very clarifying, thanks!
I am very happy with my Nacra in fact. I rebuilt it almost from scratch and I think its simplicity is also an advantage when repairs are needed. The only thing I don´t like is it´s unability to point high. In that respect,considering that there are no 5.2 available down here, I see the H17 as a good alternative (thinking in upgrading mine now). Even if it´s bigger, it appears to be light and I understand it is not much different in terms of buoyancy and crew weight, is that right?
