Answer: Q.5) A vessel took two simultaneous observations on GMT 16th Jan 1992 23h 40m 02s. The first observation of Venus
Q.4) A Vessel at Tokyo (35◦39 N, 139◦47 E) intends to sail due east for one day (speed 16 knots, Clocks advanced by one hour) then on a great circle track to San Francisco (37◦48 N; 122◦24 W). Find the maximum latitude arrived during the Great Circle passage. Answer: Q.5) Vessel steering a course of 135° T at 24 knots
Q.1 M. V. Hindship sailed from port in condition No. 8 soon after departure she grounded on an isolated rock, without damage to her hull. The drafts then were observed to be F 5.90m, A 9.30m. Calculate the following:i) The upthrust provided by the rockii) The position with respect to AP, where the grounding occurred. Answer:
Q.1 M. V. Hindship sailed from port from drafts F 8.800 m and A 9.200 m resp. with KG 7.850 m and FSM 1950 TM. On her voyage she grounded on an isolated rock, without damage to her hull. The drafts then were observed to be F 8.300 m and A 9.300 m. Determinei) The position w.r.t. AP where the
Q.2 A ship of L = 140m, COF = 2m, FWD of M/Ship, KM = 6.1 m, KG = 5.5 m, MCTC = 130 tm, TPC = 16, W = 5700T, at Drafts F/4.15 m, A/4.85 m, grounds on a rock. 10 abaft her stem. The tide then falls by 0.80 m. Calculate her V GM then and her final
Q.1 A vessel floating at drafts forward 8.0 m aft 9.0 m, grounds at a point 25 m aft of forward perpendicular. Calculate the drafts and virtual GM of the ship when the tide has fallen by 75 cm. Given MCTC 300 tm, TPC 30 t, KG 7.5 m, KM 8.5 m, Length 165 m, LCF 80 m, forward of
Q.2 A vessel of L = 140 mt, W = 16000t, MCTC = 190, TPC = 24t, LCF = 72m, KM = 8.20m, KG = 7.20m, FSM = 1370mt, draft = Fwd = 6.68m, Aft = 8.84m grounds on an isolated rock, the draft then are fwd 5.88 and aft 9.28m. Calculate following:i) The up thrust provided by the rock.ii)
Q.2 A ship of L = 150m drawing 5.0m forward and 7.0m aft. Her W = 13,000 t, TPC = 23, LCF = 73.50 m runs aground at a point 20m aft of forward perpendicular. After grounding the drafts are found to be 4.6m forward and 7.0 aft. Find:(a) Rise in tide required for the vessel to refloat. (b) Upthrust
Q.2 A vessel of L 148 m, LCF 70 m, draft forward 8.00 m, draft aft 9.80 m, TPC 32, MCTC 264 lightly grounds on gently sloping seabed. Soundings taken in that instant showed forward depth as 8.00 m and aft depth as 10.9 m. Find the draft after tide falls by (a) 30 cm (b) 2.00 m Answer:
Q.2 A ship of L = 140m, W = 16000t, LCF=72m, MCTC=190tm, FSM=137tm, KM = 8.2m, KG = 7.2m TPC=24t, draft Fwd = 6.70m. Aft = 8.85m grounds lightly on an isolated rock. The drafts now are found to be fwd 5.90m and aft 9.30m. Calculate the virtual GM and the rise of tide required to refloat the vessel. Answer:
