Picture released of boat victims

Pc Bob Chambers, of Hampshire Constabulary's marine support unit, said: "After the photo was taken the pair departed to look at the warship HMS Severn, which was anchored at Sandown Bay.

"They were seen by crew members on board the ship. After that it's believed they returned towards the beach at Whitecliff, but they were not seen again."

Coastguards believe the pair fell overboard either before or when the boat hit Bembridge Ledge - an outcrop of rock that juts dangerously into the sea.
