If you are thinking in buying a Halberg Rassy, have a good look at this one. It is not properly cheaper but it is a superior boat in many counts if not in all. This is not the racer (XP line) but an heavier stronger cruiser and a boat with an astonishing sail performance, giving its weight. If you don't believe me go to the results of the last editions of the ARC and you will find these comfortable heavy cruisers among the fastest boats of their size, among cruiser-racers.
I have already posted about the XC45 MKII:
The sail test is by Toby Hodges from Yachting world...and his opinion is not very different from mine ;-)
