Boats can sink. They are usually made of materials that allow them to displace water, and permit them to float. From time to time, that material will break down, and the boat will sink.

ANSWER. German U boats were the main threat to the British navy in WWII. As the Royal Navy dominated the German ships at every point the U boats were used to try to turn the naval war. Hitler used U boats to sink British ships that were bringing supplies that the UK had bought from the Canada and the USA so they could fight the worlds war for them. The U boats had some success but never succeeded in cutting the UK off. The British developed SONAR, RADAR, captured the enigma machines aswell as inventing depth charges and this enabled the UK to sink 70%of the U boats. Added to this the RAF bombed the U boat factories which brought an end to U boat production. U boats were basically German submarines.
