问题：
[单选] 某轮吃水d=7.00m时水线面面积AW=1200m2，则对应的淡水厘米吃水吨数为（）t/cm。
A．12.0。B．12.3。C．13.0。D．13.5。
问题：
[单选] A neutral equilibrium position for a vessel means that the metacenter is（）.
lower than the keel。at the same height as the center of gravity。exactly at midships。at the center of the waterplane area。
问题：
[单选] The difference between the starboard and port drafts caused by shifting a weight transversely is（）.
list。heel。trim。flotatio。
问题：
[单选] The difference between the starboard and port drafts due to wind or seas is called（）.
list。heel。trim。flotatio。
问题：
[单选] The Plimsoll mark on a vessel is used to（）.
align the vessel's tailshaft。determine the vessel's trim。determine the vessel's freeboard。locate the vessel's centerline。
问题：
[单选] The TPC curve，one of the hydrostatic curves in a vessel’s plans，gives the number of tons（）.
necessary to change the angle of list 1°at a given draft。necessary to change trim 1 cm at a given draft。pressure per square cm on the vessel's hull at a given draft。necessary to further immerse the vessel 1 cm at a given draft。
问题：
[单选] What is not usually a concern when loading a single-hulled tanker?（）
Bending moments。Initial stability。Draft。Trim。
问题：
[单选] Your vessel is damaged with no list，but down by the stern. There is progressive flooding and trim by the stern is increasing. What is the effect on transverse stability after the deck edge at the stern is submerged?（）
KB increases，increasing BM and therefore GM。KG increases due to the weight of the added water on deck。BM decreases from loss of water plane and greater volume。There is no effect on transverse stability。
问题：
[单选] Your vessel was damaged and initially assumed a significant list and trim; however，further increase has been slow. Based on this data，what should you expect?（）
The slowing is only temporary and the vessel will probably suddenly capsize or plunge from loss of stability due to change in the waterplane area。The vessel can probably be saved if further flooding can be stopped。The vessel will continue to slowly list and/or trim due to the free surface effect and free communication effect。The vessel will suddenly flop to the same or greater angle of list on the other side and may capsize。
