4 days/ 24 hours session

Ship theory (definitions and general theorems)

• Archimedes principle; displacement.
• Definitions of perpendiculars, draughts, plate.

Study of the determination of the displacement of a ship by reading draughts

• Determination of draughts; correction of draughts
• Scaling
• Correction of arc or counter-arc
• Drills

Calculation of the displacement and position of the vessel’s centre of gravity from hydrostatic tables with a non-zero difference

• Case of significant draught differences
• Calculation of the overall weight on board or off board
• Uncertainties on results, taking into account uncertainties on draughts and water density
• Application exercises
