Coastguard alert over empty boat
Two lifeboat crews are urgently searching for boat passengers who they
believe could be missing in the Solent.
A rigid inflatable was found washed up on the shores of Southampton Water at
0518 BST on Wednesday.
Solent Coastguard believe the boat had been occupied and it is feared its
passengers may be overboard.
Coastguards said it is "very, very urgent" that its owners are traced. The
5m (16ft) craft had the words BMW Sub Aqua on the side.
Solent Coastguard watch manager told BBC News: "All indications were that
there had been someone in the boat. This is very, very urgent."
He said a helicopter could not be sent to search until it was certain
someone had gone missing.
Anyone with information about the boat is asked to call 02392 552 100.
