I ownderd a Contest 33 for a while. She was my project boat and that particular one had some issues (apparently from her production time) that made her not suitable for my purposes. However, everything except "those issues" was indeed very well done and now from time to time I even wonder if I should have worked around them instead. (As it stands, I am going to have to buy a new boat like her very soon).
I had quite a few email messages exchanged with her designer as well, I think he may also be a designer for 31. If you have any specific questions - ask.
