From a recent report of filings in San Francisco Superior Court:
Bryerton v. Westar Marine Services, CGC-09-493160 (10/2/09)
Marine personal injury action. The plaintiff was throwing a line to another ship when his ship's captain, who was distracted and talking on a cell phone, allowed the ships to collide, which caused the plaintiff to fall to the deck and injure his right shoulder and back.
There have been quite a few cases of accidents caused by talking on a cell phone, but this is the first one I've seen where the person who allegedly caused the accident was driving a ship at the time. ("Hey, dude, gotta go. . . . I dunno, something about an iceberg. See you in New York.")
If anyone is aware of other texting-while-navigating cases, please let me know.
