A search involving Cowes lifeboat two of the Isle of Wight Coastguard search and rescue teams and the Cowes Harbourmaster has been confirmed as a hoax.
Teams of coastguards who have been on duty throughout the festival were tasked by the UK Coastguard operations centre in Fareham and the order to launch Cowes lifeboat was made just after 11pm on Saturday evening after a Mayday call was received over the VHF marine radio system.
A number of leads were being followed after what is understood to be a sailor in drink with a radio who was seen in the location prior to the distress call being made.
A land and sea search was carried out by from Island Harbour down to Newport Quay in an attempt to try and locate the distressed person.
Despite a major search effort nothing or no one has been located.
Search teams were stood down just after 1.30am on Sunday morning.
Despite the efforts of the search teams it would seem their efforts were in vain as the call was in malicious hoax that is now being investigated by Hampshire Constabulary.
