Thanks for all the feedback people!
I've read the manuals that are available from Nacra, good for general "how to put this boat together" info but not much details. The spare parts listing from them is however very nice and this year we got a official dealer here in Sweden too!
eric e: Thanks for the pics on the downhaul, exactly what I was looking for. Next season I'll finally know how to put it together.
As for the main halyard. How can a ball on the halyard run through that narrow space on the mast top (where the two "blocks" are), when raising the main, to be hooked underneath the thang on the _other_ side of the mast? I have that thang on the mast but no "ball" or rectangular blob on the halyard.
Maybe the Nacra 5.2 manual has some info on this? I would very much appreciate if someone with access to it could scan it!
Cheers, Sebastian H
