(Andy Wong/AP)On April 4, 2008, the luxury French yacht Le Ponant was crossing the Gulf of Aden between Yemen and Somalia when a swarm of speed boats surrounded the 32-cabin, three-masted vessel. A band of Somali pirates stormed the yacht, hijacking the vessel and taking all 30 of its crewmembers hostage.

A week of intense negotiations followed, ending with the release of the hostages to French military officials on April 11 in exchange for an undisclosed ransom. Shortly after the exchange, a team of French commandos tracked the pirates to a remote location in the Puntland, a breakaway region in northern Somalia. The commandos overtook them on an open stretch of desert road, attacking from helicopters and capturing six of them.

Somalia is only the latest hot spot in a worldwide renaissance of sea piracy that began a decade ago. The growth of global commerce in the past two decades crowded the oceans with cargo vessels, dry-bulk carriers and supertankers loaded with every good imaginable. The world currently transports 80 per cent of all international freight by sea. More than 10 million cargo containers are moving across the world's oceans at any one time.

The heavy ocean traffic (and its cargo) spawned a surge in sea piracy and a new breed of pirates, the bloodiest the world has seen. More than 2,400 acts of piracy were reported around the world between 2000 and 2006, roughly twice the number reported for the preceding six-year period. Although pirate attacks have at least tripled during that time period, the actual number of attacks remains unclear. Shipping companies frequently do not report attacks out of concern that it could increase insurance premiums.

And nearly every group of government monitoring sea piracy believes that number is seriously undercounted. The Australian government estimates the actual number of piracy attacks is 2,000 per cent higher. Piracy is estimated to cost between $13 billion US and $16 billion every year and could cost substantially more in coming years.

More than 2,400 acts of piracy were reported around the world between 2000 and 2006, roughly twice the number reported for the preceding six-year period.

"Piracy is not going away," says Peter Chalk, an international security analyst at the RAND Institute. "In fact, its getting more serious and more violent, and its only a matter of time before you need to take it more seriously."

That's starting to happen. The potential of a disastrous environmental spill resulting from an attack finally forced the international community to clamp down on sea piracy. International law allows any government vessel to repress an act of piracy in international waters. On Oct. 30, 2007, two American destroyers, the USS Porter and the USS Arleigh Burke, attacked and sank two Somali pirate vessels after the pirates captured the Japanese tanker, Golden Mori.

Last week, the U.N. Security Council voted in favor of a new measure that would allow the U.S. military to engage Somalian sea pirates.

But Somalia is not the only place with piracy outfits this organized. Somalia is a relative latecomer to contemporary sea piracy. Since 2000, southeast Asia has had the most dangerous waters in the world. Malaysia and the islands of the Indonesian archipelago have seen the lion's share of sea piracy since 2000. Also troubling: the waters off Nigeria and Iraq.

Recently captured Somali pirates claim they belonged to an organized militia that engaged in piracy to raise funds. Organizations have started attacking from more than one ship simultaneously using a number of quasi-military tactics.

Violence has become an endemic feature of piracy, particularly over the last five to 10 years. The birth of the illicit global arms trade that emerged after the fall of the Soviet Union in 1991 made it easier for many (who might feel less inclined to pursue piracy if they lacked guns) to become pirates, according to Chalk. The arms trade has made cheap and powerful weapons available in many parts of the world.

Five to six years ago, when pirates attacked, they used machetes, knives and pistols. "Today," says Noel Choong, the current director of the International Maritime Bureau's anti-piracy office in Kuala Lumpur, Malaysia. "They come equipped with AK-47s, M-16s, rifle grenades and [rocket-propelled grenades]."

This not only poses an enormous risk in terms of human security, but also endangers maritime security. Attacked ships can be left unmanned, turning into rogue vessels. "In many maritime chokepoints where attacks often occur, this creates a serious risk of a collision," says Chalk.

"The truth is that modern piracy ... is a violent, bloody, ruthless practice," said Captain Jayant Abhyankar, Deputy Director of the International Maritime Bureau at a conference in Singapore, "made the more fearsome by the knowledge on the part of the victims that they are on their own and absolutely defenseless and that no help is waiting just round the corner."
