Q9. A vessel of Length L = 150 mtrs, CF = 2.5m forward of midship, KM = 6.0M, KG = 5.4m, MCTC = 120, W = 6000t, TPC = 15, ata draft of F : 4.25m, A : 5.00m ground on a rock at midship. The Tide then falls and draft at midship is observed to be 4.46m. Calculate her virtual GM then and her drafts forward and aft.
Solution –
Correction to aft draft = 0.75 ⨯ 75/150
= 0.375
Midship draft = 4.625
Fall in water at midship = (4.625 – 4.46)
= 0.165
16.5 = P/15 + P⨯ 75/120 ⨯75/150
P = 43.51 tonnes
