I agree as well. Yachts bigger than Limitless are ships. We call them Gigayachts today, but Lady Moura, Mipos, Pelorus, Octopus, Rising Sun and Dubai are all too big to be considered yachts in my mind.
They might have superyacht finish and interiors, but as with houses, at some point it is not a villa but a castle. Too big for society to accept as reasonable.
If yacht buyers wanted to excel in design and refined taste I would be much happier than seeing those floating palaces. What R A is doing right, is that he is having several yachts, but bigger is certainly not better.
If you want a really big yacht, I think between 80 and 90 meters will be more than enough. If you want a really nice and still big yacht, I think 55 to 60 meters is ideal. If you just want a great superyacht, any size between 30 and 50 meter will fulfill your dreams.
The real challenge is to get a good, special and purposeful design, but especially today it seems as the buyers donīt care any longer. Semicustom boats of 45 to 55 meters is more pollution than progress seen from a designers point of view...
But before this thread is completely derailed, have a look at the thread on Designer Yachts where discussions on style and quality over size and quantity can continue...
