STRAND Cruise and Travel Centre (071-836 6363) has published a new edition of its Passenger Cargo Ship Voyages brochure with information on freighter journeys to Australia, South America and other destinations. A 30-day trip from Felixstowe to Fremantle, for example, with the Mediterranean Shipping Company, costs pounds 2,400 in an outside cabin. Strand Cruise and Travel Centre says of today's cargo vessels: 'Most have a lounge, library, TV/video, and many have a fitness room and swimming pool. Passengers take their meals with the officers and crew in their dining-room.'
