MARINA DEL REY: The 16-year-old Southern California girl attempting to become the youngest person to sail around the world alone says she is stopping in Mexico with power problems. On her blog, Abby Sunderland wrote that she’s headed for Cabo San Lucas to add a “new battery” because solar panels and wind generators aren’t keeping up with her energy needs. Sunderland said she will restart the sail in her 40-foot craft Wild Eyes soon. She set sail on Jan 23 from Marina Del Rey and plans to be at sea for five or six months.
