A shrimp trawler dragged out to sea by the tsunami last year in Japan is floating off the coast of Alaska. It is adrift, and potentially a danger to navigation, and it has more than 2000 gallons of diesel fuel aboard. The Coast Guard is planning to sink it in deep water. As a number of commenters on the article have pointed out, the fuel alone is worth $10,000. The ship is worth $200,000 as scrap steel. So why does it make more sense to sink it then for a salvager to tow it to a dismantler, assuming that it isn't worth something still as a ship? (It is still floating, many months after the disaster). If it cost $50,000 to grab it and drag it to a dismantler, it would still be profitable.
Do any of my readers have an ocean-going tug? I understand that under the law of maritime salvage, it is ours for the taking.
UPDATE: There is still a country where initiative and ambition exist...Canada.
UPDATE 2: The article now says that the Canadians who were planning to tow it apparently found that they couldn't--so cannon fire is still the plan.
