Royal Navy divers searching for vessel's jackstaff that was lost overboard in Portsmouth Harbour

A Royal Navy navigation warning has been put in place after one of its vessels inadvertently lost its jackstaff and tripod overboard.
The notification has been sent out to all all vessels operating just off North Corner Jetty (East) in HM Naval Base Portsmouth.
They are being warned to "navigate with particular caution, if required to operate in this vicinity".
It is not yet clear which to which Royal Navy ship the jackstaff belongs.
The notification came at around the same time HMS Prince of Wales returned to Portsmouth after her deployment to the United States - however, Forces News understands the jackstaff was not from the aircraft carrier.
Several ships have recently returned home to Portsmouth for Christmas including HMS Dauntless amongst others.
The name Jack is thought to be derived from the naval term jackstaff, which is the small vertical spar or pole on the bow of a ship and from where the Union Jack is flown.
A Royal Navy spokesperson said: "We are aware of an issue involving a jackstaff. Royal Navy divers will attempt to retrieve it in due course."
