I'd agree with Frank. My last lot have now gone (and you'll understand my tears John !) I really don't think anything else is going to happen now - and it has been drifting steadily down since the peak. Out for (financially) a good profit.
But from an emotional viewpoint it's "Goodnight Vienna" to dear old P&O I'm afraid - another piece of Great British History gone to Johnny Foreigner. What with the French and Spanish owning the fishing fleets, the Americans our cruise liners, the Dubai-ians (??!!) our cross channel ferries (at least for a short while before they can flog 'em off) and the Danish our once great merchant fleet I think that's probably the last of our shipping. Apart from the Isle of Wight ferry I suppose and a few Blackpool pleasure craft.
