These long crested fully developed sea states were representative of high Sea State 5, low Sea State 6 and middle Sea State 7 with significant wave heights of approximately 3.78 metres, 4.42 metres and 7.53 metres, respectively. The results were compared to previous experiments on a Patrol Frigate (PF) without a bulwark. It was seen that the bulwark on the FFG-7 effectively eliminated deck wetness in high Sea State 5 and low Sea State 6. Deck wetness did occur in middle Sea State 7 on the FFG-7 in head and bow seas at ship speeds of 20 and 25 knots. Sonar dome emergence was seen to occur on the FFG-7 in high Sea State 5 and low Sea State 6 with full emergence occurring in middle Sea State 7. (Author) 收起
