General Arrangement and Profile Plans, Layouts in general primarily represent functional / utilising aspect of the vessel, showing precisely accommodation, owner and guests features, crew space, engine room, and also other very important content, such as navigation, safety regulations, classification, etc.
 General Arrangement helps to get first very real visual impression of the boat outside and inside, but even more important, to understand the size of space that exterior shell creates in interior of the boat.
 All the layouts are very accurate, though they are made in real dimensions, only scaled, giving possibility to the client, designer and naval architect to discuss, revise and improve interior arrangement, influencing in a way exterior design too. In this early stage of the project, all changes are still possible, that's why this phase in design process is very important.
