So, the vessel actually sinks more in the forward end and less in the after end. So, apart from sinkage, there is a trim by bow, and as you will know, trim by bow is not a very desirable phenomenon. This goes on if you go to shallower and shallower water; this vessel will go on like this till it touches the bottom. This has of course effect on resistance and the effects will be the change in pressure will give a change in pressure forces which is the pressure resistance and this would also change the frictional resistance, because we have got increased velocity past the ship. Am I clear? This is one effect which we can understand.
