In this work the comfort of two different passenger vessels is improved by minimizing the Overall Motion Sickness Index (OMSI). Various hull transformations are considered for both vessels to investigate their influence on passenger’s comfort. These are categorized into two groups: geometric and hull from transformations. The transformations are performed using MaxSurf Modeler developed by Bentley systems, based on the Lackenby Method. Seakeeping analysis is performed for each new hull using an in-house strip theory code, accounting for various heading angles and a specific operating scenario described by the JONSWAP Spectrum. The improved hulls based on the study of OMSI are compared to their parent hulls regarding their RAOs plots. A similar comparison is performed regarding the absolute vertical accelerations, at strategic locations on the main deck and the hull resistance. Finally, the improved hull forms are compared to their parent hulls regarding their operability index based on comfort criteria.
