4) Find the significant relative bow motion amplitude and the number of occurrence of deck wetness per hour for 120m ship with an effective freeboard of 7m while she is steaming at 20 knots into head seas in a long crested seaway. The response spectrum of this ship is given in Table 1. CF will be taken as 1. Table 1: The response spectrum of a ship 0.25 0.50 0.75 1.00 1.25 1.50 1.75 S,(o.) 0.05 0.60 3.50 11 8.50 3 0.5
