Marchioness passed under Southwark Bridge, she was hit twice by Bowbelles bow. The first impact was from Marchionesss stern, which had the effect of turning the smaller vessel to port. The second impact was from the stern, and caused the pleasure boat to pivot round the bow of Bowbelle, and turn it on its side, probably to an angle of 120°. The upper superstructure of Marchioness was ripped off by Bowbelles anchor. The lower saloon was quickly flooded and the lights went out. The weight and momentum of Bowbelle pushed Marchioness underwater and she sank, stern first, within 30 seconds of being hit. McGowan had been thrown from the boat into the water, but climbed back on board to tie open the port side door, which led to the dance floor, to allow several people to escape. One eyewitness to the crash, Keith Fawkes-Underwood, who viewed the incident from the south bank of the Thames, reported: The barge collided with the pleasure boat hitting it in about its centre then mounted it, pushing it under the water like a toy boat. Within a matter of about 20 seconds the pleasure boat had totally disappeared underneath the water. Of the 130 people on board Marchioness, 79 survived and 51 died. The dead included de Vasconcellos and Faldo. No-one on Bowbelle was injured. Marchioness sank so quickly that most people were unable to locate or use the life rafts, buoys or jackets. Survival of those on Marchioness depended partly on their location within the vessel. There were 41 people known to have been on the forward deck and wheelhouse, of whom 9 died and 32 survived, a survival rate of 78%. Of the 13 people known to have been in the lower saloon, 9 died and 4 survived (a 31% survival rate). One of those from the lower saloon who survived was Iain Philpott, who said in his statement to the police: I remember turning around to head towards the windows to escape the boat, the water started coming in the boat through the window, I knew at this point the boat was going to go down. Within a matter of seconds the general lights went out, everything was in darkness ... I was then thrown forward by a wall of water, the whole boat filled with water instantly ... When I surfaced I was some distance away from the Marchioness which
