Answer my own question (from https://www.gov.uk/wreck-and-salvage-law
Definition of wreck
According to section 255 of the Merchant Shipping Act 1995, the definition of wreck includes “jetsam, flotsam, lagan and derelict found in or on the shores of the sea or any tidal water”.
Jetsam, flotsam, lagan and derelict
Jetsam describes goods cast overboard to lighten a vessel in danger of sinking. The vessel may still perish.
Flotsam describes goods lost from a ship which has sunk or otherwise perished. Goods are recoverable because they remain afloat.
Lagan describes goods cast overboard from a ship which afterwards perishes. The goods are buoyed so they can be recovered.
Derelict describes property, whether vessel or cargo, which has been abandoned and deserted at sea by those who were in charge of it without any hope of recovering it.
If a boat comes off its moorings, it isn’t generally classified as a wreck for the purposes of the Merchant Shipping Act 1995, as it hasn’t been abandoned without hope of recovery.
Also, buoys such as data buoys and mooring buoys aren’t classed as wreck. However, buoys which form part of fishing equipment may be classed as wreck when adrift.
