Adrift describes a vessel floating on water that is not anchored, moored, or under control, moving freely at the mercy of wind and current. It indicates a boat has broken free or is broken down, posing a hazard, and can also refer to unsecured gear or items left loose on deck.

Key Aspects of "Adrift":
Uncontrolled Movement: The vessel is drifting without power, steering, or proper anchorage.

Broken Moorings: It often implies a boat has broken away from its dock, mooring buoy, or anchor.

Items/Gear: Gear or equipment that is not properly stowed or fastened down is considered "adrift" on deck.

Emergency Context: Being adrift is dangerous, as the vessel cannot follow a planned course and risks collision or grounding.
