If you look at the detailed specs for boats, some builders just list LOA and LWL on new stuff, some also list either LOD or "hull length" to give a good idea of how much actual space it has. AT seems to only list LOA and LWL, but Beneteau lists all 3 on their sailboats, for example.
Example: My boat was sold as 38 feet. It's actually 38' LOD (length of the hull mold across the deck). LWL is 33'6". Measured true LOA including the swim platform and pulpit is 42'4". If sold now, it would be called a 42 or 43 most likely.
LOA [including pulpit and swim step] makes sense for a boat yard/marina calculating room occupied when boat is wet or on the hard... caus after all... that is the length of "rental" space being occupied by the boat. However... for using a boat [either regarding its capability in sea conditions and/or inside room for comfortable living-aboard] I believe the deck length from stem to stern should be utilized. Caus, after all... if you remove the pulpit and swim step... you have little change of the boat's seakeeping ability or live-aboard comfort.
