The distinction
Scale
The Azimut is longer and considerably wider, which is reflected in its interior volume.
Character
Azimut is more theatrical. Princess is quieter and more disciplined in presentation.
Decision
Compare the actual exterior areas, machinery access and tender arrangement before treating either model as the obvious answer.
The final decision
A useful comparison must move beyond published specifications. The right yacht is the one whose layout, systems, condition and ownership demands correspond to the way it will be used.
