This question is designed to get help from someone (with some important important questions), so that I can get an understanding on why I cannot quite get the correct answer for this question Longtitudinal Centre of Gravity for Ship Cargo.

Also establishing if I have actually answered Longtitudinal Centre of Gravity for Ship Cargo question correctly and maybe the answer from the textbook is not quite correct.


If the Longtitudinal Centre of Gravity of a ship (without added load) is behind (aft) of it's Longtitudinal Centre of Flotation, does this affect a ships change in aft draft ?

For change in draft aft calculations, does added weight always have to be added at Longtitudinal Centre of Flotation, parallel sinkage calculated there and then change in trim calculation for movement of weight to it's actual position done from there ?

or

Can an Added weight be positioned at the ships original Longtitudinal Centre of Gravity, Parallel sinkage calculated at LCG and then the change in trim calculation for movement of weight to it's actual position done from there ?

I am thinking of a situation when it is calculated that a cargo load is to be positioned aft of the ship Longtitudinal Centre of Gravity, when the ship Longtitudinal Centre of Gravity is behind Longtitudinal Centre of Flotation.

  • $\begingroup$ @SolarMike Hi Solar Mike, thanks very much for your reply. The question is related to the Longtitudinal Centre of Gravity for Ship Cargo question . The reason I have put his question up tough, is because I have tried my best in the other question to get the answer of 46.2 m , but my answer is falling short by 0. 3 m at 46.5 m. So with this question I am trying to establish if there is something I have missed that is important. $\endgroup$ Aug 3 '21 at 2:35

  • $\begingroup$ Hi @r13 Are you a naval architect ? I have made the question more clearer now as to how it relates to my original question which has all the details engineering.stackexchange.com/questions/35275/… . You have to realize that I have actually already attempted calculations for this questions, but my answer is not quite agreeing with the textbook. $\endgroup$ Aug 11 '21 at 2:39
  • $\begingroup$ Hi @r13 So I am writing this question to understand the concept of when a ships centre of gravity is behind its centre of flotation does this affect it's trim. Also how does parallel sinkage work with this situation when a load has to be positioned at a certain pint from the stern to increase the aft draft b y a certain amount (in this case 0.3 m). $\endgroup$ Aug 11 '21 at 2:39
