The 'Enlarged Ship' Concept, (ESC), as previously introduced by Keuning and Pinkster (1995) as a serious improved fast monahull concept, is now expanded upon with subsequent model testing, in irregular head waves, of a number of such design concepts. The effect of a modified bow shape, made possible by the ESC, is also investigated and evaluated with regard to its possible impact on operability in a seaway. Also the vessel resistance is measured and compared with the previously predicted improvements: Parallel to the model testing, calculations are carried out with both linear (SEAWAY) and non linear codes (FASTSHIP) to predict heave and pitch motions and, in particular, the distribution of the peak vertical accelerations. Finally, an economic appraisal of the designs is also shown.
