Humber Coastguard have appealed to the missing East Yorkshire yachtsman directly to urgently make contact with them.
The 69-year-old man is late on his return to Scarborough from Germany and his worried family have appealed for help. He was last seen in the Keil Canal, Brunsbuttel, Germany and telephoned his son on July 4th to say he was planning to come home.
Search aircraft will resume their search later this morning. Humber Coastguard is asking any vessel who believes they may have sighted the yacht to urgently contact any Coastguard Station with information.
