Investigators say a lightning strike may have caused a fire on a yacht, and the fire spread to several other boats.

Titusville resident Mike Richart witnessed the fire, and caught the blaze on camera. Richart said that at first, he wasn't sure what was happening.

"I saw smoke when I was in my boat and I saw smoke going by the window and I thought it was weird clouds then I came out and saw that boat was on fire," said Richart.

Firefighters say a 40-foot yacht and two other boats were on fire by the time they arrived.

Those firefighters had to wait before putting out the flames because of extreme lightning in the area.

No injuries were reported.
