2.5 Basic Dimensions and Hull Form Characteristics
• LOALOA(length over all )(length over all )
: overall length of the vessel• DWLDWL(design waterline)(design waterline)
: water line where the ship is designed to
float• FPFP(forward perpendicular)(forward perpendicular)
: imaginary vertical line where the bow
intersects the DWL• APAP(aft perpendicular)(aft perpendicular)
: imaginary vertical line located at either
the rudder stock or intersection of the stern with DWL
