THE SEAKEEPING PERFORMANCE OF FAST SINGLE-HULL AND MULTI-HULL PASSENGER FERRIES
A complete seakeeping performance assessment of a fast passenger vessel with regard to passenger comfort should consider motion sickness, safety of footing and impact accelerations. However, motion sickness is often more of a problem in a lower sea state than safety of footing and wave impacts, and therefore the seakeeping performance of a fast passenger vessel is dictated by passenger seasickness. The seasickness criteria is dealt with in detail in this paper, whereas the other passenger comfort criteria are covered briefly. The linear seakeeping performance prediction method, developed in a Nordic project in 1988, can be used to investigate the operability of fast vessels in head seas also by using passenger seasickness as an operability-limiting criteria, and so the seakeeping performance of some mono and twin hull ships was predicted with regard to passenger seasickness. All the vessels studied are not originally designed as fast passenger vessels, but they cover a wide range of possible hull forms so that new passenger vessel designs should fall within this field. In order to obtain a more accurate full-scale data from motion-induced seasickness, a comprehensive full-scale seasickness trial was carried out in May 1993 on board a catamaran. The main results of this full-scale trial are presented in the appendix of the paper.
