Displacement curves 4 a From the following information construct a displacement curve Displacement tonnes 376 736 1352 2050 3140 4450 Mean draft m 1 2 3 4 5 6 b From this curve nd the displacement at a draft of m. c If this ship floats at m mean draft and then loads 850 tonnes of cargo and discharges 200 tonnes of cargo nd the new mean draft. d Find the approximate TPC at m mean draft. 5 The following information is taken from a ship s displacement scale Displacement tonnes 335 1022 1949 2929 3852 4841 Mean draft m 1 2 3 a Construct the displacement curve for this ship and from it nd the draft when the displacement is 2650 tonnes. b If this ship arrived in port with a mean draft of m discharged her cargo loaded 200 tonnes of bunkers and completed with a mean draft of 2 m nd how much cargo she discharged. c Assuming that the ship s light draft is 1 m nd the deadweight when the ship is floating in salt water at a mean draft of m. 6 a From the following information construct a displacement curve Displacement tonnes 320 880 1420 2070 2800
