. This stage delineates more precisely such features as hull form based on a faired set of lines, powering based on model testing, sea keeping and maneuvering characteristics, the effect of number of propellers on hull form, structural details, use of different types of steel, spacing and type of frames. Paramount , among the contract design features, is a weight and center of gravity estimate taking into account the location and weight of each major item in the ship. The final general arrangement is also developed during this stage. This fixes the overall volumes and areas of cargo, machinery, stores, fuel oil, fresh water, living and utility spaces and their interrelationship , as well as their relationship to other features such as cargo handling equipment, and machinery ponents. d. Detai Design The final stage of ship design is the development of detailed working plans. These plans are the installation and construction instruction to the metal workers, machinery vendors, pipe fitters, etc. As such, they are not considered to be a part of the basic design) process. One unique element to consider in this stage of the design is that up to this point, each phase of the design is passed from one engineering group to another. At this stage the interchange is from engineer to artisan, th
