When navigating in a narrow channel on which side should it keep as close as is safe?

When navigating in a narrow channel, vessels should keep to the starboard side (the right side when facing forward) as closely as is safe. This practice aligns with the International Regulations for Preventing Collisions at Sea (COLREGs), which recommend that vessels adhere to the "starboard rule" to maintain safe passage and avoid collisions. Additionally, it allows for smoother traffic flow, especially in areas with limited space.
