What does 'anchor aweigh' indicate?

'Anchor aweigh' signifies that the anchor has broken free from the seabed and is no longer in contact with it, meaning that it is clear of the bottom. This is a crucial point in seamanship as it indicates that the vessel is ready to maneuver or proceed under its own power. When the anchor is aweigh, it confirms that the crew can safely continue navigating without the risk of dragging the anchor.

In practical terms, this phrase is often used during anchoring operations to communicate to the crew that the heavy work of lifting the anchor is successfully completed, allowing for a smooth transition to sailing. Understanding this terminology is vital for maintaining proper communication and operational awareness onboard a vessel.
