What is the obligation of the give-way vessel as described in Rule 17d?

The obligation of the give-way vessel as described in Rule 17d is to keep out of the way of the stand-on vessel. This rule is part of the COLREGs and establishes responsibilities for vessels to avoid collision, particularly in scenarios where one vessel is required to allow another to proceed.

When a vessel is designated as the give-way vessel, it is required to take action to avoid collision by maneuvering appropriately, which primarily means not impeding the passage of the stand-on vessel. This could involve changing course or speed but is fundamentally focused on yielding the right of way. The give-way vessel must assess the situation and take actions that ensure the safe navigation of both vessels involved.

Maintaining constant speed, signaling, or changing course frequently do not directly fulfill the obligation of the give-way vessel as outlined in Rule 17d. Instead, the primary action needs to be a conscious effort to avoid any risk of collision, making "keeping out of the way" the correct choice in this scenario.
