To create a successful new genera- tion of cruise ships, cruise operators, naval architects, and interior design- ers must work together to find solutions. ey must learn from prob- lems in previous designs and look for new technical possibilities that can improve the performance, environ- mental friendliness, and safety of new ships. How can passenger capac- ity be increased? Which layout should be used for maximum balcony ratio? How can food service, entertainment, and activities be improved onboard? Can the fuel consumption be reduced? Which hull form has the best sea keeping characteristics? What is the building cost per passenger in the new design? Can a large vessel be delivered in less than 3.5 years? e most important part, however, will be to understand the passengers, their demands, and expectations. Both the naval architect and the inte- rior designer must look at the ship from the passengerĀs point of view to be able to create a winning design for the next 25 years. Tankers, bulk carriers, and container vessels are a heavy industry business?standard vessels built in long series at competitive prices. Success in the cruise business demands di erent skills. We must provide a unique expe- rience for the passengers to ful l their expectations and to make them come back for more cruises.
