Marine Accident Brief: Collision of Two Recreational Motorboats on the St. Croix River near Bayport, Minnesota, July 3, 1999

About 0125 on July 3, 1999, a 27-foot Advantage recreational motorboat with three men on board and a 22-foot Bayliner recreational motorboat with two men on board collided on the St. Croix River near Bayport, Minnesota. No one witnessed the accident; however, the damage path across the top of the Bayliner indicated that the Advantage struck the starboard side of the Bayliner, forward of the windshield, and passed over the motorboat. All five occupants of the two motorboats died as a result of the collision. The three occupants of the Advantage died from drowning. The two occupants of the Bayliner died from blunt force trauma. The National Transportation Safety Board determines that the probable cause of the collision between the Advantage and Bayliner recreational vessels was alcohol impairment, which led the two boat operators to indulge in high speed operations at night, and which impaired their ability to determine the movements of other vessels and to take appropriate action to avoid a collision.
