The report presents the ship performance observations and the ice conditions in the northern Baltic Sea from the winter of 1992. Ice channels were profiled by cross sectional drilling at Ajos, Virpiniemi and twice at Raahe. Twenty five ship transits were recorded at the Raahe harbor ice channel between the period of February 19 and March 11. The observers took part in six voyages with four different vessels during February 18 to March 4. The average speed was recorded together with the prevailing ice conditions. One outstanding feature from the Raahe channel study was the immense variation in the average speed for vessels of similar characteristics. Besides the cold technological facts the human factor was highlighted.
