BOSTON (AP) - A tour boat with 174 people on board has been evacuated after it ran aground in Boston Harbor and began taking on water.
      
Coast Guard Petty Officer Connie Terrell says two people reported back and knee injuries after the incident, which happened off Deer Island at about 10 a.m. Saturday.
      
She says rescuers removed 168 passengers and six crew members from the 87-foot Boston-based vessel "The Massachusetts." Terrell says the passengers were taken to a pier in Hull, about three miles from the boat.
      
Workers aboard "The Massachusetts" were pumping out the water as it began to sink bow first into the harbor Saturday afternoon.
      
Deputy Harbormaster Chuck Evans says the boat's operators said it collided with a rocky ledge as it traveled at 18 knots.
