Science / Tides and Currents / Current Line: A graduated line attached to a current pole formerly used in measuring the velocity of the current. The line was marked in such a manner that the speed of the current, expressed in knots and tenths, was indicated directly by the length of line carried out by the current pole in a specified interval of time. When marked for a 60-second run, the principal divisions for whole knots were spaced at 101.33 feet and the subdivisions for tenths of knots were spaced at 10.13 feet. The current line was also known as a log line.
