Most (if not all) buyers of new Nauticats have them customized using their personal requirement programs. If you have the means (or madness) to spend close to a million dollars for 40 + foot boat, there shouldn't be any other option.
As Stan mentioned, finding any pre-owned Nauticat for sale in this country newer than the late 1980's will be next to impossible. The older ones, although loved through the years by their owners, will have some upgrade issues. The value however, has actually increased on mine - based upon recent sales.
