One Class Surveyor got onboard of a 45000 DWT new construction Chemical Tanker a week before delivery， he carried out the initial Safety Equipment survey in accordance with the Fire Fighting and Life-saving Control Plan.Surveyor noted that the vessel had two (2) 15 persons’ Life-rafts at each side， and One (1) 6 persons’ Life-raft on the forward main deck. The surveyor verified the Life-rafts’ certificate and found that the max storing height of one 15 person’s Life-raft at port side to be 18 meters as indicated on its certificate. But the surveyor checked the drawings and noted that actual storing position was 18.5 meters above the Lightweight water line of this vessel.Surveyor recommended shipyard to change the Life-raft or re-locate the life-raft in order to comply with the stowing height requirement as indicated on its certificate. Do you think the Surveyor’s recommendation is correct？（）A.
The surveyor’s comment was not correct； because the Life-raft has the Hydra-Static Releaser， should not care the height of Storing Position
B.
The surveyor’s comment was correct； because if the Storing height was over the Limit of the Life-raft， It may damage the Life-raft when throwing off to the water
C.
The surveyor’s comment was not correct； the storing position was the same location as showing on the approved drawings
D.
The surveyor’s comment was correct； as a surveyor， he can give any comment as he like
