The man was moored up in The Wash waiting to return to Gibraltar Point, Lincolnshire, when he fell ill on board. He later died despite efforts to revive him.

A man has died on board his 20 foot catamaran while moored in The Wash, off the Lincolnshire coast.

The emergency services were alerted just after 3pm on 16 August, when a request for a medi-vac was broadcast from the vessel.

The man had collapsed on board after a day of sailing.

Both of the RNLI Skegness lifeboats, the Skegness and Chapel St Leonards Coastguard Rescue Teams and a UK search and rescue helicopter responded.

A windfarm vessel also offered assistance.

Despite efforts to revive the man, he died on board.

A spokesman for the Maritime and Coastguard Agency said: “At about 3.05pm today (16 August) the UK Coastguard received a VHF radio call from a catamaran vessel requesting medical assistance.”

“Skegness RNLI inshore and all weather lifeboats, Skegness and Chapel St Leonards Coastguard Rescue Teams and the UK Coastguard search and rescue helicopter based at Humberside were sent to assist. A windfarm vessel also proceeded to the area to offer assistance,” continued the spokesman.

“A casualty has been taken to Hull Royal Infirmary by the UK Coastguard helicopter. Hull Coastguard Rescue Team manned the landing site at the hospital,” concluded the spokesman.
