How fast is the Nordhavn 62?

I'm curious, could you tell me more about the speed capabilities of the Nordhavn 62? I understand that it's a renowned vessel for long-range cruising, but I'm particularly interested in its maximum speed under different conditions. How does it perform in calm waters versus rougher seas? And is there a noticeable difference in its speed when fully loaded versus empty? I'm eager to learn more about this aspect of the Nordhavn 62's performance.
