Woman killed in boat collision on Lake Washington

A 37-year-old woman was killed Saturday night when the sailboat on which she was riding was struck by a speeding motorboat on Lake Washington.

Three other people were taken to Harborview Medical Center with non-life-threatening injuries.

Seattle police say that a motorboat driven by a 17-year-old male was traveling at high speed around 8:45 p.m. when it collided with the rear end of the sailboat.

Police spokeswoman Renee Witt said the woman was killed on impact.

A Seattle Police Harbor Patrol boat responded to the scene and began CPR on the woman, who was taken to shore and pronounced dead. A spokeswoman from the Seattle Fire Department said the woman was thrown from the boat.

The King County Medical Examiner's Office hasn't identified the woman.

The accident occurred in the waters between Seward Park and Mercer Island, off the 4500 block of Lake Washington Boulevard South.

Two teenagers in the motorboat, the 17-year-old driver and a 16-year-old female, were treated for minor injuries. A 45-year-old male on the sailboat was also transported to the hospital with a back injury. A third male passenger on the sailboat was not injured.

Witt said witnesses on shore described the motorboat as traveling at a high speed when it hit the sailboat, went up over the back of it and struck the woman.

Seattle police are still investigating the accident.
