The document outlines various scenarios according to the collision regulations (COLREG) regarding actions to be taken by sailing vessels (SV) and power-driven vessels (PD) to avoid collisions. It explains rules for when vessels are approaching each other, overtaking, and navigating in traffic separation schemes (TSS), detailing necessary actions like altering course, keeping lookout, and determining the risk of collision (ROC). Specific rules and actions are provided for scenarios involving different combinations of vessel types and configurations.
