RedactedNarrative: As we approached you could see a large amount of black smoke coming from the area out from the Lake Geneva municipal launch, with a large crowd of boats around it. Water Safety Patrol was keeping all of the boat traffic away from the fire as the Linn fire boat attempted to put out the fire.  We then began to assist with keeping all of the boat traffic at a safe distance. Water Safety Patrol had the occupants of the boat on their boat and reported that everyone was okay and that there were no injuries.
  
  Vessel Operator reported the following.  At approximately 10:30am, he and the other occupants were cruising along the shoreline traveling southbound just out from pier 880. They were traveling at approximately 5mph when the voltage dropped. He then brought the speed up to approximately 15mph to hopefully charge the battery.  A few minutes later the boat died and some white smoke started to come from the engine area. He thought everything was okay because the smoke was "Normal" for a boat.  They then called Water Safety Patrol and asked for a tow.  While waiting for Water Safety Patrol the Operator got into the water because the other three occupants did not know how to swim very well and he thought that he could help them when they got into the water. Another boat then came by and was going to let them on their boat when Water Safety Patrol arrived and had them all get on their boat.  Then the fire boat arrived and put out the fire.
  
  The vessel appeared to be a total loss with only the lower section of the hull intact.
