材料：
At 1100 UTC on 28 May 2003，the container vessel P&O Nedlloyd Vespucci and the yacht Wahkuna collided in the English Channel in poor visibility．
Each vessel had detected the other by radar when at a range of about 6 miles．The container ship was on a course of 255°（T）at a speed of 25 knots．The yacht was on the port bow of the container ship on a course of 012°（C）at a speed of 7.5 knots，and was due to pass about 8 cables ahead of the container ship．The skipper of the yacht，however，incorrectly estimated from his radar display that P&O Nedlloyd Vespucci was passing 1.5 miles ahead of Wahkuna，and reduced speed by disengaging his engine．This action，which also resulted in a substantial alteration in the yacht&39;s heading as it lost steerage，put the two vessels on a collision course．The actions of the yacht，the CPA of which now appeared as 2 cables to port on ARPA，concerned and confused the master of P&O Nedlloyd Vespucci，but he was reluctant to take any manoeuvring action because he was uncertain of what the yacht would do next．
Minutes later，the vessels collided and the bulbous bow of P&O Nedlloyd Vespucci struck the forward part of Wahkuna&39;s hull，demolishing the first 3m of her hull and dismasting her．Despite having sent a lookout to the port bridge wing，the master of the container ship was not aware that a collision had occurred，and continued on passage．The yacht crew had to abandon to a liferaft，where they stayed for 5.5 hours before being rescued.

D.neither P&O Nedlloyd Vespucci nor Wahkuna
It appears that ________ was not a factor contributing to the collision．A.The inability of the yacht skipper to use radar effectively
