Amazing.

How long can this go on?

The longer that shipping companies and their countries continue to allow ships being held hostage, the better equipped and organized the pirates will get; the longer their range will be; the more ships and the more valuable ships they will hijack; the higher ransoms they'll demand; and the more difficult they will be to eventually eradicate.

These trends are already underway:
The location of the latest attack, far out to sea, suggested that the pirates may be expanding their range in an effort to avoid the multinational naval patrols now plying the Gulf of Aden and the Arabian Sea.

“I’m stunned by the range of it,” said Adm. Mike Mullen, the chairman of the Joint Chiefs of Staff, at a news conference in Washington. The ship’s distance from the coast was “the longest distance I’ve seen for any of these incidents,” he said.

The vessel was headed for the United States via the Cape of Good Hope when it was seized, Reuters reported.

Only a few years ago, the average ransom was in the tens of thousands to hundreds of thousands of dollars. Now payments can range from $500,000 to $2 million.

The pirates’ profits are set to reach a record $50 million in 2008, Somali officials say. Shipping firms are usually prepared to pay, because the sums are low compared with the value of the ships.

Maritime experts recently have noticed a new development in the gulf — the pirates’ use of “mother ships,” large oceangoing trawlers carrying fleets of speedboats which are then deployed when a new prize is encountered.

“They launch these boats and they’re like wild dogs,” said Mr. Choong in Kuala Lumpur. “They attack the ship from the port, from starboard, from all points, shooting, scaring the captain, firing RPGs and forcing the ship to stop.”
