Which vessel type is second in the hierarchy of vessels according to the rules?

The hierarchy of vessels, as outlined in the International Regulations for Preventing Collisions at Sea (COLREGs), establishes a priority system for how different types of vessels should navigate around one another to prevent collisions. Vessels constrained by draft, such as large vessels operating in shallow waters, hold a significant position in this hierarchy because their ability to maneuver is severely limited compared to other types of vessels.

When navigating, it is important for all mariners to understand that vessels constrained by draft are often unable to change course or speed significantly without risking grounding. This gives them priority in many situations to ensure their safe passage is maintained. They have specific regulations that protect them, making it clear that other vessels must give way to them to avoid dangerous situations.

While other vessel types, such as fishing vessels, sailing vessels, and power-driven vessels, have their own rights and responsibilities, vessels constrained by draft rank higher in this system, emphasizing the need to prioritize their movements to ensure safe and unobstructed navigation in constrained waters. Understanding this priority is crucial for safe maritime operations.
