Scenario briefing

You hear a fog signal forward of the beam. The target is detected very close (under 2 NM) on a steady bearing. Rule 19(e): when close-quarters cannot be avoided by altering course alone, REDUCE speed to the minimum at which the vessel can be kept on course ( 3 kn in this sim tap DEAD SLOW for 2 kn, or use REV in 5% steps; EMERG ASTERN is available if you must take all way off). Combine with a small course alteration if needed.

Why it matters

COLREG knowledge is the foundation of safe ship handling. Most maritime collisions happen because watchkeepers either misidentified the situation, applied the wrong rule, or acted too late. This scenario lets you train pattern recognition + correct response under time pressure — the exact skill the rules are designed to support. RYA, Yachtmaster, STCW and most national exams expect you to apply COLREGs reflexively, not just recite them.
