A search sparked by a report that parts of a pleasure vessel had been seen off the coast of East Sussex has been stood down.
HM Coastguard led the search in the English Channel, south of Hastings, from about 08.45 BST on Thursday.
A coastguard helicopter, an aircraft, an all-weather lifeboat and several non-emergency vessels were assisting the operation.
The coastguard found the debris was from a boat which had run aground about three weeks ago, and its occupants had made it safely to shore.
