Parallel indexing is a well-established method of constantly monitoring a vessel’s position. In marine navigation, the main goal of radar is to detect any vessels in the vicinity of the ship or any obstacles, such as land masses, in reduced visibility. Radar is also widely used in good visibility. Technological improvements and development refinements have allowed users to stretch the use of radar to its limits. The purpose of this book is to explain how it can be done safely. This book underlines the most common errors and limitations that affect parallel indexing and have been observed by pilots of the Corporation of the Lower St Lawrence (CLSLP) during their assignments.
