For many organizations, legacy infrastructure is be

Royal Yacht International has announced PROJECT M, a fully custom 132-metre Lürssensuperyacht exceeding 6,000 GT. But for Royal Yacht International Founder and CEO Tommaso Chiabra, the project is less about size than what it represents. This press release features multimedia.

And replacement cost can change dramatically between contract signing and delivery. “People look at purchase price. Sophisticated owners look at replacement value. What would somebody have to spend, and how long would they have to wait, to recreate your yacht when it is delivered?” For RYI, this is changing the role of the yacht broker. HUNDREDS OF MI
