I visited the Navigator as a guest in Seattle, as was very impressed by the ships physical qualities as well as the wonderful canapes offered to guests.
The ship itself bears a definite likeness to the Silversea ships, as might be expected, as she was built in the same Mariotti yards in Genoa. The ship is obviously a bit larger than the Silversea ships, and a little more dramatic in certain areas, especially the main centrum area with the glass elevators. Especially pleasant are the wide corridors which create a feeling of openness and light. The pool area is very nice and almost a larger carbon copy of the Silversea ships. A very nice touch are the teak table and chairs, which are absent on Silversea, and always lend a feeling of class and luxury.
The alternate dining area, the Portofino Grill, is very nicely done, as is the main dining room. The dining room unfortunately is not 2 decks high as on the Diamond and the Gauguin, but one can't have everything.
