Final answer:
The correct statement for an overtaking situation at sea is that the power-driven vessel must keep out of the way of the sailing vessel, as per the International Regulations for Preventing Collisions at Sea.
Step-by-step explanation:
The statement that applies to a situation where a sailing vessel is overtaking a power-driven vessel is: c. The power-driven vessel must keep out of the way of the sailing vessel. This rule is part of the International Regulations for Preventing Collisions at Sea (COLREGs). According to the COLREGs, the overtaking vessel, regardless of whether it is sailing or power-driven, must keep clear of the vessel being overtaken. It's important to recognize that in the context of COLREGs, an overtaking situation is determined by the approach angle, not the type of propulsion of the vessels involved. Therefore, the sailing vessel is considered the give-way vessel and must maneuver to avoid a collision.
