Recent tendencies in superyacht designs have been accompanied by the enlargement of the dimensions of yacht windows. Yacht designers are motivated by the requests of yacht owners to increase the transparency of their vessels to offer panoramic views of the surroundings while being shielded from the elements. Current standards for yacht windows consider window panes to be mechanically independent of the adjacent ship structure, limiting the size of uninterrupted glazed areas. In this study, a section of the top tier of a yacht fully enclosed by glass is considered, with glass panels spanning from deck level to the top of the yacht. The edges of the glass panels are connected to transverse beam members. The behaviour of the structure was then assessed in response to loads set forth by classification societies for the design of yacht structures. These loads correspond to specific wave conditions a yacht is expected to sail in and include external pressures, inertial loads and gravity. A finite element model was created through which the mechanical behaviour of the structure was calculated. This behaviour is compared to existing criteria for both ship structural design and the design of structural glass components. Suitable glass panel thicknesses and transverse beam materials and sizes are recommended.
