But "length between perpendiculars" (LBP) is not the same as LOA. In over forty years of ship-related employment I've never come across "OAL" in relation to vessel measurement, whether in the registration paperwork, tonnage certificates or classification society nomenclature. Always happy to learn something new though, thanks!
