Since you gave no dimensions nor angle for the cable, I will assume it is verticalI will ignore cable massthis then is a trick question a) ship hull floatstension 0 b) ship is fully supported by cabletension 16500kg if hull is sunk in a) then tension 16500kg - (mass of water that hull displaces)you need to know volume of hull
I think you're missing some information here, like the angle that the crane's cable makes between it's arm or the angle that the crane's arm makes between the horizontal direction.
Portion size is very important even for foods that are good for you
