| Abstract: | The vessels considered here for the squat studies are a bulk carrier and an High Speed Craft (HSC). The bulk carrier of full form (CB=0.81) is used for validation purpose and subsequently the numerical computations are performed for a High Speed Craft with fine hull form of CB=0.467. A high speed ferry, with LCB and LCF quite aft of midship is considered for squat study. For a vessel speed of above 6.0 knots and for a waterway width greater than the vessel length there appears to be a sudden increase in sinkage at the stern accompanied by a large value of bow emergence. It could be seen that the speed of the vessel has a much greater influence on the sinkage and trim of the vessel than the waterway restrictions. |
