材料：

When SEA EMPRESS was two or three cables from the Channel entrance，the pilot saw from the changing aspect of the Outer Leading Lights that there was a set to the east．He ordered a course change of 5° to port．The vessel，which was now closing with the Mid Channel Rocks Light Buoy，started to turn to port．The pilot saw the Outer Leading Lights close and then open to the east as the bows entered the channel．The Buoy was very close to starboard and the pilot now saw that the fixed red and fixed white lights of the Outer Leading Lights，the ones indicating the east side of the deepest water in the Channel entrance，were also open to the east．

After the bows had passed the Middle Channel Rocks Light to starboard there was a shuddering vibration，then a sound from the deck below of liquid being forced under pressure，accompanied by a strong smell of oil．The helmsman reported that the vessel was not steering and the pilot ordered&39; full astern&39;．The Chief Officer recorded this order and the vessel&39;s position，which was 1.4 cables northwest of Middle Channel Rocks Light．

SEA EMPRESS，which was trimming by the head and taking a starboard list，continued to run ahead as the main engine was on full astern．There were further main engine movements and the vessel finally lost all way after she grounded again in a position about 3.3 cables south-by-west of the Mill Bay Buoy．The main engine was put to &39;stop&39;．SEA EMPRESS was by this time significantly trimmed by the head and had taken an 18° list to starboard with the starboard fore part of the deck awash and was heading in a northwesterly direction．
