Opinion A Corrected Version on Positioning of Pivot Point

by Capt. Santosha K. Nayak - published on 18 November 2020

Understanding the fundamentals of the pivot point is highly required for understanding the alteration of the courses. Pivot point is an imaginary point on the vessel which turns on a circular path on the perimeter of vessel’s turning circle when the vessel makes a turn.
