Developments in the maritime sector are diverse. Due to the sometimes extreme sizes of the parts, only certain components are developed with the support of prototyping. Outboard and inboard engines for small to mid-sized boats are in no way inferior to the highly advanced engines of the automotive industry. For larger sea vehicles, the development of new components tends to occur in the peripheral area of the drives. Turbochargers, pumps and compressors play an important role here in implementing alternative fuels, and thus a reduction of emissions. In some areas of maritime applications, e.g. yachts, customers order minimal batches or even one-off units as seawater-resistant components.
