A more thorough explanation:

Definition: Logan is another term for lagan, which refers to goods that are abandoned at sea but attached to a buoy so that they may be recovered. It can also refer to wreckage or cargo lying on the seabed.

Examples:

• A fishing net that has become detached from a boat and is floating in the ocean is considered logan.
• If a ship sinks and some of its cargo remains attached to a buoy, that cargo is also considered logan.
• Logan can also refer to items that have sunk to the bottom of the ocean and are no longer attached to a buoy.

The examples illustrate how logan refers to goods or cargo that have been lost at sea but may still be recovered. It is important to note that logan is different from flotsam, jetsam, and waveson, which refer to different types of items that have been lost at sea.
