• Exercise 1: Density and relative density.

• Exercise 2: Water pressure.

• Exercise 3: Flotation .

• Exercise 4: Some important terms – displacement;  deadweight;   form coefficient;  reserve buoyancy; Tonnes per centimetre.

• Exercise 5: Effect of density on draft and displacement – FWA ; DWA ; loadliness of ship.

• Exercise 6: Centre of gravity – definition ; factor affecting its position ; shift of COG  of a ship splitting into three components.

• Exercise 7: Final KG – GG₁ formula and its limitation to one weight at a weight at a tme ; moments by kneel .

• Exercise 8: Centre of buoyancy – definition ; indication of its postion by KB, AB or HB; KB of ships of various shapes.

• Exercise 9: Transverse statical stability – list , heel;  their relation to COG and COB;  transverse shift of B; metacentric height ; righting moment for both,  small and large angle of heel.

• Exercise 10: Equilibrium of ships – stable equilibrium ; unstable equilibrium ; neutral equilibrium. 

• Exercise 11: More about unstable equilibrium —  angle of loll ; behaviour of vessel  at angle of loll.

• Exercise 12 : Free surface effect – general explanation ; free surface correction (FSC);  solid GM ; fluid GM; calculation of FSC ; effect of tank-breadth on FSC .

• Exercise 13 : List – explanation of factor causing list ; problem based on the same.

• Exercise 14: Stiff and tender vessels.

• Exercise 15: Staility of vessel with deck cargo of timer.
