Minimum passing distance for ships at sea?

The minimum passing distance for ships at sea is generally governed by the rules of the International Regulations for Preventing Collisions at Sea (COLREGs). While specific distances may vary based on local regulations and conditions, a common guideline is to maintain at least 1 nautical mile of separation between vessels to ensure safety. Additionally, factors such as visibility, vessel size, and traffic density can influence the required distance. Ultimately, maintaining a safe distance is crucial for avoiding collisions and ensuring navigational safety.
