To Be or Not To Be a Narrow Channel

from The Maritime Education Podcast · host Captain Barry Sadler

A narrow channel has no formal dimensional definition in COLREGs or IMO conventions; instead, courts, pilots, VTS authorities and the MCA determine it by practical navigational constraint. A waterway is considered a narrow channel when vessels must follow the dredged or charted track for safe navigation, with limited room for meeting, overtaking or deviation. Case Law reaffirms that narrowness is a question of fact, based on depth, width, hydrodynamics and vessel operational constraints. Rule 9 therefore applies whenever the waterway’s characteristics confine navigation.Barry discusses the facts surrounding these common navigational features and why we need to be cautious when using them.The link to our new quiz app mentioned in the podcast is below.https://captainbarrysadler-colregs-quiz.base44.appCome and Visit our Website https://www.captainbarrysadler.com/At Captain Barry Sadler Maritime Training & Consultancy we deliver industry-leading online courses, oral exam preparation, and professional resources for deck officers, cadets, and maritime professionals.
