Around 100 passengers remain stranded outside Portsmouth, after it's been announced part of the harbour will be closed all day.
It's due to the discovery of a WWII bomb this morning, which will be towed away and destroyed by the Royal Navy.
The Historic Dockyard will be closed off all day to deal with the incident.
A 500-metre cordon is in place around the bomb as a precaution, leaving all cross-channel ferries stuck.
The Clipper was on it's way to the mainland after leaving Jersey last night.
The captain of naval base says they are working to deal with the incident in the safest way possible.
The discovery was made at 5am this morning by a barge dredging the harbour ahead of the arrival of HMS Queen Elizabeth next spring – the Royal Navy’s new 65,000-tonne aircraft carrier.
