Well this is the sort of thing that really ruins your day. Sorry to hear about your problem User. It's hard to know from what you've posted, and I certainly am not the most technically qualified person to opine (not that it ever stops me), but if the mast partners and mast step were installed in the wrong place (i.e., off centered), I don't see a builder (particularly this one) undertaking that fix. You are talking about cutting a new hole in the deck for the mast, then closing up the old in a cosmetically acceptable way. That may require new routing of running rigging and wiring. Then, you need to move the mast step. I can't imagine that gets done without having to re-do the interior furniture and cabin floorboards. You also might need to replace/move the chainplates, which again has cosmetic issues, not just structural (and ofttimes it's the cosmetic issues that make repairs very difficult).

I won't get into the details, but I have a little professional experience with the Tartan/C&C situation at this point, and its problems do not appear to be isolated.
