Updated at 9 p.m. with information about the 129th Rescue Wing's involvment with the mission.
The U.S. Coast Guard continued its search Monday for two adults and two children missing since Sunday evening off the coast around 65 miles west of Pillar Point near Half Moon Bay.
Sunday evening, the 129th Rescue Wing of the California Air National Guard joined them in their search. Earlier Monday morning, the wing launched an HH-60G Pave Hawk rescue helicopter to continue assisting the search, according to their Facebook page. A spokesperson for the unit informed Mountain View Patch that by the evening, the 129th Rescue Wing no longer would be involved in the search-and-rescue mission; the Coast Guard will continued the search using water and surface vessels only.
The four boaters abandoned ship around 5:30 p.m. after their 29-foot sailboat, Charmblow, started taking on water and the vessel's electronics failed, U.S. Coast Guard Lt. Heather Lampert said.
The people on board may possibly have made it on to a makeshift life raft before the ship sank, Lampert said. Coast Guard helicopters, airplanes and boats searched the area, but didn't located the missing boat.
Patch will update with information as it becomes available.
