3)Length Between Perpendiculars (LBP): The length between the forward and aft perpendiculars measured along the summer loadline.
MouldedBeam:Measured at the amidships section is the maximum moulded breadth of theship
Moulded Draft: Measured from the base line to the summer load line at the midship section.
Moulded Depth: Measured from the base line to the heel of the upper deck beam at the ship’s side amidships.
Sheer: Curvature of decks in the longitudinal direction.
Rise of Floor (or Deadrise): The rise of the bottom shell plating line above the base line.
