This project has designed a highly efficient, zero-emission, fully electric ferry for the Southampton to Isle of Wight route. Designing a vessel of this size and complexity requires a good understanding of the requirements and a full design space exploration is vital for a successful design. An iterative process was followed to make sure the best possible design solution was achieved. The new vessel is longer, at 95.6 metres, and can carry 1020 passengers and 231 car-equivalent units (CEU), improving on the current Raptor Class. Despite this, the new hull design has achieved an 18% reduction in resistance, compared to basis vessels. This was achieved using a systematic numerical optimisation. An all-electric architecture was chosen for the propulsion system, leading to a 64% reduction in lifetime CO2 impact and a 62% reduction in annual operation costs. Analyses have also been carried out to design the most suitable propulsor and to optimise the interaction between the hull and propulsor. Hull appendages have been designed and a lightweight structure designed and tested using finite element analysis modelling. Additionally, an optimisation of the interior spaces has been undertaken to ensure a high level of passenger comfort, as well as maximising vessel revenue. Rigorous model testing has been undertaken to ensure a fully functional design that meets the stakeholders need, requirements and wishes, while still conforming to the current legislative framework. This report presents the design of a technically feasible, economically viable and systematically validated zero emission ferry.
