The 'Enlarged Ship Concept' (ESC) was successfully applied to a fast semi-planing 26 m patrol boat by Keuning and Pinkster. Their results showed a significant performance improvement both in a technical and economical sense. In order to investigate if ESC may also render a similarly successful design strategy for a RO-RO (roll-on-roll-off)/Passenger vessel which is representative for present services in the UK-West Europe route, the underlying study was carried out. The outcome of this study is that some important results are quite the opposite to those of the patrol boat; this is mainly due to the large difference in vessel types and Froude numbers involved. Within a given payload weight, the larger RO-RO vessels have more cargo carrying capacity in terms of trailers; in other words, the enlarged vessels can carry more trailers if the trailers are not fully laden. Furthermore, the larger vessels are less vulnerable in damaged condition since the lower hold is not used for cargo and can therefore freely be optimally subdivided. Also advantageous is the fact that the draft decreases as the length increases which results in a higher freeboard for the larger vessels. Summarising, it appears that application of ESC to this type of vessel creates more income possibilities for the shipowners and a much safer vessel, but it produces a more expensive ship to buy and exploit.
