After 42 days ashore, the Chandalar was removed from Upton Beach and cut up for disposal yesterday. The county hired Parker Diving Service for a job estimated to cost anywhere between $26,000 and $42,000. The effort was organized by Marin County Parks in collaboration with the sheriff’s office and Greater Farallones National Marine Sanctuary, which will help pay for the costs. “The county is paying for it, but we are working with the Greater Farallones National Marine Sanctuary, who might be able to cover some or all of the cost of removal,” said parks director Max Korten. Wednesday felt like a defeat for those who spent the past two weeks trying to get the vessel back to sea. Their plans revolved around endless digging, a pulley system and an old Coast Guard lifeboat. The effort was backed by some longtime residents but raised the ire of others who saw the boat as an eyesore and its owner as a nuisance. In August, deputies gave Logan Walker a deadline of Aug. 31 to remove the boat. In response, Mr. Walker obtained a temporary restraining order against the sheriff’s office, which opposed his request for more time, saying the boat obstructed the public’s ability to enjoy the beach. A judge granted him until noon on Monday, Sept. 11 to remove his boat, which is also his home.
