Vessel "A" is on course 000 True. Vessel "B" is on a head-on course and is bearing 355 True, 200 yards away from vessel "A". To ensure a safe passing, vessel "A" should _____________.

To ensure a safe passing, vessel "A" should maneuver to ensure a port to port passing with vessel "B." Under the International Regulations for Preventing Collisions at Sea (COLREGs), when two power-driven vessels are approaching each other in a head-on situation, both vessels are required to alter their course to starboard to maintain a safe distance. This allows for a starboard-to-starboard passing, which is generally considered a safer option as it minimizes the chance of collision by keeping both vessels clear of each other's paths and reducing the risk of confusion about their intentions.

However, in this scenario, vessel "A" being on course 000 True and vessel "B" bearing 355 True indicates that they are indeed approaching each other head-on. For vessel "A" to pass safely, maneuvering for a port-to-port passing would involve vessel "A" altering its course to starboard while encouraging vessel "B" to do the same. This is preferable because it provides a clear and direct passing route, minimizing the potential for overlap in their navigation paths.

By following this guidance, vessel "A" can successfully navigate a head-on situation without compromising safety, which is paramount in maritime operations. In summary, maneuvering to ensure a
