  A northern California man's left hand was partially severed after being struck by a boat off Maui. It is the latest in a string of incidents involving propeller injuries. Saturday's incident has ignited talk of mandating propeller guards.
  
  Nearly a thousand swimmers took part in Monday's Labor Day Waikiki Roughwater swim. A handful of these athletes also competed in the Maui Channel swim from Lanai to Maui, where a 41-year-old man was hit by an escort boat about 200 yards off Kaanapali Beach. County officials say the 28-foot boat had drifted into a safe zone.
  
  "Apparently he just was somebody yelled at him and he said oh I got to get out of here, made a turn hit one the swimmers almost hit the second one," said, the race director of the Waikiki Roughwater swim. "We have a couple of boats that are on the course but they're way outside, they're nowhere near the swimmers."
