PASSENGERS on-board Arcadia are due to set sail on their world tour, 24 hours late.

They were stranded overnight on board the Southampton based super-ship, ahead of the 101 day cruise.

Arcadia was initially expected to depart yesterday but before the master, Commodore Steve Burgoine, could put to sea it was discovered a problem had developed with the vessel's emergency electrical back-up system forcing the ship to stay in port.

Work continued throughout the night and into the day.

According to a company spokesman Arcadia and her 1,860 guests on board, were expected to leave the Eastern Docks at about 4pm.

During the delay P&O Cruises supplied transport for any passenger who wanted to go into the city centre while on the ship all facilities were open as normal.

"The ship's new departure time will not have any serious, long term effect on the voyage,'' said a P&O Cruises' spokesman.

Arcadia is due back in Southampton on Thursday, April 16 after visiting more than 35 ports in 19 countries during the cruise.
