Hello everyone, I was researching explorer yachts and I got to know about a new builder called 'Hawk Yachts'. They are apparently specializing in large explorer yachts and they intend to penetrate the market through half-if-not-less-than-half running costs. We're talking really big yachts here (103m and over 6000 gross tonnage). As I was reading an interview with the company's president, he stated that ALL luxury yachts are wasting so much money in the form of running cost as they don't adopt commercial-grade machinery; this in turn makes the running cost twice as otherwise. He gave an example of a yacht he was the captain of (Lady Moura) - stating that at the time it was designed, there were no "yacht machinery" for a yacht of that caliber, so it adopted a commercial approach instead, and that in turn made it one of the most efficient yachts in its size category (till this day, apparently). On a different not, I read an article a while ago (don't remember the publisher tbh) who claimed that Lurssen's Octopus costs $20 million annually just to run things smoothly; I was frankly shocked that such costs are incurred for a yacht that is in perfect condition, which means that this is normal for a yacht of this size/kind. My questions, therefore, are the following: 1- Is it true that Octopus does cost that much to maintain on an annual basis? 2- Could the implementation of 'commercial-grade' machinery drop the running cost by more than half? 3- If 'commercial' is indeed that effective, what is the drawback? There must be a compromise because it doesn't sound logical that yacht owners will embrace such high costs when they can lower them dramatically. Thanks!
