701. What term indicates the length measured along the summer load line from the intersection of that load line with the foreside of the stem and the intersection of that load line with the aft side of the rudder post?

Length between perpendiculars is the distance along the summer load line from the forward perpendicular at the stem to the aft perpendicular at the rudder post. This measurement differs from length overall, register length, and length on the waterline, which are defined by different reference points.
