If you’ve been through MITAGS’ Navigation Skills Assessment Program (NSAPĀ®)⢠and/or have sat in a classroom with MITAGS’ Instructor and Lead NSAPĀ® Assessor, Captain Jerry Hasselbach, odds are you’ve seen him present on or discuss the Doubt Signal.
Captain Hasselbach has had the ability over the last several years to witness and assess over 1000 NSAPĀ® sessions. During these sessions, Captain Hasselbach has gained more knowledge and lessons learned than he could have originally imagined, leading to what has developed into a presentation on the Doubt Signal.
In his presentation, he shares one of the most frequently misunderstood situations that is covered under the ColRegs. The situation being referenced is the simple situation of having another vessel crossing from oneās port side, and oneās status and resultant duties under the ColRegs changing several times as oneās mental state changes.
Captain Hasselbach has put his Doubt Signal presentation into written form to share it with the maritime community in hopes that the outcome will be better understood by all mariners and be taught in maritime schools around the world. . Click the button below to read this article.
