Popis: In this study, the experimental heave and pitch motion responses of inverted bow hulls in regular head waves were investigated. Comparison of the pitch and heave motion responses of two modified versions of an NA8-14 British Ship Research Association reference fishing vessel with 45 and 60 degrees inverted bows was performed. The findings showed that decreasing the inversion angle of the bow to 45 degrees improves the dynamic performance of the model. Moreover, the interactions between the heave and pitch motions led to the frequent appearance of 'kinks' in coupled form in response to the heave and pitch motions.
