ParticipantThe forward contour line is the interseccion of the ships bow with each waterline, and is measured from the origin (in Delftship is the point X=0,) in some cases is the aft perpendicular, so measure longitudinally from X=0 to the interseccion of each of the waterlines with the ship’s bow.
The aft countor line is the inerseccion of the stern line with each waterline, pretty much same as forward but is refered to the stern of the ship.
Hope this info helps.
Regards
