After Perpendicular (A.P.) : A perpendicular drawn to the waterline at the point where the aft side of the rudder post meets the summer load line. Where no rudder post is fitted it is taken as the centre line of the rudder stock.
Forward Perpendicular (F.P.) : A perpendicular drawn to the waterline at the point where the foreside of the stem meets the summer load line.
Length Between Perpendicular (L.P.P. / L.B.P.) : The length between the forward and the aft perpendiculars measured along the summer load line.
