Design and specifications
As a sister ship to Royal Princess, Regal Princess shares many of the same dimensions, features, and overall design.[28][29] The ship measures, has a length of 330.0 m, a draught of 8.5 m, and a beam of 38.4 m. She is powered by a diesel-electric genset system, with four total Wärtsilä engines, producing a total output of 62.4 MW.[30] Main propulsion is via two propellers, each driven by a 18 MW electric motor.[30] The system gives the vessel a service speed of 22 kn and a maximum speed of 22.9 kn.[30] The ship houses 1,780 passenger cabins and 751 crew cabins.[30] Of the 1,780 passenger cabins, 81% have a balcony.[30] The ship has a maximum capacity of 5,600 passengers and crew.[30]
Describing the style that inspired much of the interior design on Regal Princess, Giacomo Mortola, head architect at ship design firm GEM, explained:
"Mainly it is a combination of warm, elegant tones that convey a feeling of comfort and sophistication. One example – a favourite architect of mine, Frank Lloyd Wright, used wood, bronze, and leather-covered walls, and I used these materials to impart the look and feel of the aft dining room. These materials were also used in the entertainment areas including the Princess Theater, Vista Lounge, and TV Studio contributing to the acoustic quality in these areas.[29]"
Notable features aboard the ship include a multi-level atrium, a theater, various dining rooms and restaurants, and pools.[29]
