The Navy says negotiations are underway to decide what to do with a 50-foot yacht that washed ashore at a base near San Diego.

The Navy said Wednesday that strong winds and a high tide carried the Mona Mona more than two weeks ago to a beach at Naval Air Station North Island in Coronado.

The Navy is trying to decide with the owner of the San Francisco-registered yacht whether the ocean-trawler can be saved.

Images shown on KSWB-TV show the once-luxury cruiser partially submerged in water. A witness says windows are broken and the vessel is filling with sand.

Thomas Ritter, Coronado's assistant city manager, says anchor lines occasionally break on boats that are left unsupervised for long periods of time in the upscale peninsular enclave.
