In [[navigation]], a '''rhumb line''', '''rhumb''' ({{IPAc-en|r|ʌ|m}}), or '''loxodrome''' is an [[arc (geometry)|arc]] crossing all [[meridian (geography)|meridians]] of [[longitude]] at the same [[angle]], that is, a path with constant [[azimuth]] ([[bearing (navigation)|bearing]] as measured relative to [[true north]]).
Navigation on a fixed [[course (navigation)|course]] (i.e., [[steering]] the vessel to follow a constant [[cardinal direction]]) would result in a rhumb-line [[track (navigation)|track]].
