In this paper we investigate the seakeeping effects (especially vertical acceleration) in an reversed ship bow form. Reversed or inverted bow form for ships have special features that discriminate them from conventional bow form. Slight technical data has been released on the seakeeping performance and acceleration effects of inverted bows ship. Earlier studies have stated in relation to vertical motions and accelerations,water spray (deck wetness) ,slamming criteria,retained that we can anticipated many deviations in ship responses. For analysis about acceleration, we restructured a NA8-14 fishing vessel model from British ship research association series in solid works and Rhinoceros soft wares and finally three scale models (60degree bow form , 45degree bow form and conventional bow form) were contrived and tested in regular waves from head seas at towing tank. The variances between acceleration results of three models experimental tests are categorized in terms time.
