The ship left harbour with all four main engines running. When she was clear of the harbour area full service speed was set. The engine setting was maintained up to the accident. The wind was southerly, 8-10 m/s. Visibility was good, with rain showers.
At 2000 hrs the watch on the bridge was taken by the second officer B and the third officer (The estonia had two second officers, here designated second officer A and second officer B).
The voyage proceeded normally. Sea conditions along the Estonian coast were moderate, but became more rough when the ship left the sheltered waters. The ship had a slight starboard list due to a combination of athwartships weight disposition, cargo disposition and wind pressure on the port side.
As the voyage continued the wind velocity increased gradually and the wind veered to south-west. Visibility was generally more than 10 nautical miles. At midnight the wind was south-westerly 15-20 m/s with a significant wave height of 3-4 m. The rolling and pitching of the vessel increased gradually, and some passengers became seasick.
At about 0025 hrs the ESTONIA reached a waypoint at position 59°20´ N, 22°00´ E and from there headed true course 287°. The speed was about 14 knots and the vessel encountered the seas on her port bow. Due to increasing rolling, the fin stabilisers were extended.
