Which vessels are required to follow COLREGs?

The answer reflects the comprehensive scope of the COLREGs, which state that all vessels must adhere to these regulations when navigating the high seas and in navigable waters. This means that every type of vessel, regardless of its size, purpose, or nature – whether it be commercial, recreational, or otherwise – is obligated to follow the rules set forth in the COLREGs to ensure safety and prevent collisions at sea.

The regulations are designed to promote safe navigation, requiring all vessels to be aware of, and adhere to, specific responsibilities and guidelines. This inclusivity is critical, as it ensures that all mariners are following a common set of standards, thereby reducing the potential for accidents and misunderstandings while at sea.

The other choices suggest a limited application of the COLREGs, which contradicts the intention of these regulations. Suggesting they apply only to recreational boats, commercial vessels, or large cargo ships overlooks the fundamental principle that safety at sea is a universal concern, applicable to all vessels engaged in maritime navigation.
