More details emerging -- they are trying to downplay the attack, but just found another article, where they say the ship was actually hit with some RPG-s.
(Someone also needs to ask BBC, why "pirate" is in quotes.)

Passengers tell of 'pirate' attack
http://news.bbc.co.uk/2/hi/africa/4410826.stm
Edith Laird, from Seattle in the US, told the BBC News website she was only four rooms away from where a rocket-propelled grenade (RPG) hit the Seabourn Spirit, about 100 miles (160km) from the Somali coast.
"My daughter saw the pirates out of our window. There were at least three RPGs that hit the ship, one in a stateroom four doors down from our cabin.
......
"I looked out of the window and saw a small boat with about five people in it about 20 yards (20m) away.
"One of them clearly had a rifle. Later I realised that two of them had rifles and one had some kind of rocket launcher.
"They were firing the rifle and then fired the rocket launcher twice. One of the rockets certainly hit the ship - it went through the side of the liner into a passenger's suite. The couple were in there at the time so it was a bit of an unpleasant experience.
NPR referred to them as "alleged" pirates.
As if they needed an eyepatch and parrot for confirmation.
Or should I have called it N-P-aaarrrrrgh?
Every ship should have appropiate weaponry to destroy pirates. And it ought to be a major crime to fail to report an attack.
