How To Determine Whether The Ship Is Sagging or Hogging

The forward draft of your ship 36' 04" and the after draft is 40' 02". The draft amidship is 38' 08". Your vessel is:


SOLUTION:

Step 1. We have to get the mean draft. Let us add forward and after draft.

36' 04" + 40' 027" = 76' 06"

And then divide the sum of the two drafts by 2.

76' 06" ÷ 2 = 38' 03" is our mean draft.   

Step 2. Let us analyze whether our ship is in hogging or sagging condition.

By the given drafts forward and aft, the waterline amidships should be at 38' 03". However, the actual draft at amidships is 38' 08". Therefore, the vessel is sagged.
