As you pass through the door at the top of the stairs, what will you see and experience? That is the challenge in designing ferry interiors. As a naval architect I see several lay- ers of thought that go into the design of an effective interior layout. The first has to do with an understanding of the passenger. While on a ferry, whether it is for a 30 minute trip or a two hour trip, the passenger needs some essential services and likely desires some benefi- cial services. Examples of essential services are places to sit and restroom facilities. Examples of beneficial serv- ices include a hot food service and workspaces for people with computers. In Seattle, the opportunity to purchase an espresso drink likely falls into the essential service category. In any case, the array of necessary and beneficial services that should be considered depends on the length of route and the type of passengers. For example, if the ferry provides transportation for school children on a regular basis, the interior should have some furniture and decora- tions to suit that group of riders. As with any vessel, the list of wants and wishes needs to be balanced against the space available and the construction budget. This is the process known as space planning. One way to create a space plan is through use of bubble diagrams (see example) where each activity or space gets a bubble. The size of the bubble depends upon the percentage of rider- ship likely to engage in the activity while onboard the vessel. Bubbles con- nected by arrows show the level of interaction between activities or show passenger movement between spaces. For example, eating food and working on homework for school children both require seating and a tabletop. However, studying also needs a quiet space which may be in conflict with the noise of a dining area. A bubble chart can provide a quick understanding of the relationships between different spaces onboard a ferry. Circle 254 on Reader Service Card 24 Maritime Reporter & Engineering News
