Coastguards searched all night for the men

The alarm was raised on Sunday evening when the pair failed to return to Conwy.

Four coastguard teams, three lifeboats and a RAF rescue helicopter were involved in the search for the men on board their 20ft power boat Sea Dancer.

Coastguards at Holyhead on Anglesey broadcast emergency messages to the boat while the search went on but received no response.

The search area included the Menai Straits, Conwy Bay and along the east coast of Anglesey.

Coastguards scoured the beaches on foot

Coastguards also checked harbours including the Isle of Man and considered calling in a RAF Nimrod search aircraft.

The pair in their 50s, were found in the early hours of Monday moored in Cemaes Bay in Anglesey.

They were totally unaware of the search for them, until they returned to their boat and heard a radio message.
