Curves of Form, TPC, MCT & Bonjean Integration

Inside this lesson
  • Describe what curves of form are and how they're generated
  • Read hydrostatic values from a table at a given draft
  • Define TPC (tonnes per centimetre immersion) and compute it from waterplane area and density
  • Use TPC to estimate the draft change from a known weight addition
  • Define MCT 1 cm and use it to estimate change of trim from a trimming moment
  • Describe Bonjean curves and use Simpson's rule to integrate sectional area along the ship's length
