About RhumbLine

What is a Rhumb Line?

A sailor preparing to start an ocean journey, whether it's one of a few miles or several hundred, 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 plan sponsors navigate challenging financial waters.
