Parallel Indexing (PI) for Course Alteration | Radar Navigation Tutorial

This video explains how parallel indexing is used during course alteration to monitor a vessel’s position along the planned track. Using radar tools such as EBL and VRM, the Officer of the Watch can quickly detect any deviation from the track and take immediate corrective action. The tutorial demonstrates a practical example along the One Fathom Bank TSS, showing how to set and monitor parallel index lines before and after altering course. #parallelindexing #NavigationalAid #marineradar #arpa #passageplanning #voyageplanning #seamanship #maritime #seafarer #seaman #bsmt #maritimestudents #ecdis https://youtu.be/iVYZ9DNW9GE https://youtu.be/h9XE9Z2wOFw https://youtu.be/veHDoss_sCU
