M3000-1 · Navigation · M3000-1.1 Plan and Conduct Safe Navigation

This lesson covers GPS failure modes and ECDIS error chains in a command context — how a Master identifies, responds to, and records electronic navigation system failures whilst maintaining an independently verified position.

Independent preparatory study aligned to the MCA Master (Yachts less than 3000 GT) examination syllabus (updated June 2026). Not an MCA-approved course and confers no credit toward a Certificate of Competency.
