facilitate the specification requirements. This involved a people flow analysis of the GA with user scenarios at different times of day. Significant research was carried out into contemporary interior design, resulting in a range of mood boards for several themes and the key interior


3.1 EXTERIOR FORM AND GA DEVELOPMENT


The key objective of the interior design was to allude to the design heritage of the golden era of superliners such as the Normandie, by developing a sleek, streamlined dynamic shape. To communicate the speed and modernity of the design visual form techniques were used to


reduce the


superstructure and accentuate the perceived length of the vessel. To develop a


perceived form

communicating the capability and technology of the platform a simple form language was developed relating all the visual components.


The composite mood board is shown in Figure 5 visually communicating the three key design facets of the exterior form: aggression, precision,


power, streamline;


structural, organic, simple; architectural, cubism, minimalism. The first relates to the exterior form. This should convey a sense of power, presence and capability of

The exterior form development is shown in Figure 6. Where the sleekness of the form is emphasised by boat tailing the rear of the vessel and sculpting the aft surfaces on the upper decks to visually connect with the feature on the main deck.

The surface form detail is shown in the CAD exterior model
