The cruise Line was CTC, yes Russian
At the time of your skihalypin being the larger, with 2 smaller liners the Felix Djezerinski, and
cant think of the third, did cruises on all 3.
At the time far better than P&O, and just behind Sitmar and their fleet of the Fair series of cruise liners
Fair sky, Fair sea, Fair wind, later to be acquired by P&O
