What is a Rhumb Line?

A sailor preparing to start an ocean journey charts a course using one or more rhumb lines. Rhumb lines are straight lines drawn on a nautical chart to represent the most easily navigated course which avoids hazards, from point A to point B. When navigating unfamiliar waters, a rhumb line is an essential aide. RhumbLine Advisers was founded to help our clients navigate challenging financial waters.
