Developments in shipbuilding have been driven by needs to simplify the engineering and manufacturing. The cause is not just to become more competitive but also to avoid problems in controlling engineering and manufacturing costs. Two recent examples carried out with ShipConstructor include a small 7.5-m aluminum police boat and a 120-m car/truck/pax mono-hull fast ferry. Both vessels have been 3-D modeled using the same ShipConstructor software, which can be scaled to be a price efficient solution for small and large vessels at the same time. The software maintains the same functionality. The reduced cost version is only limited in the maximum number of parts in the project.
