LEE COUNTY, Fla.- More than $50,000 was spent on repairs to a multi-million dollar yacht, just before it went up in flames off the coast of Sanibel earlier this month.

Investigators say the fire was accidental, and an electrical problem sparked the whole thing.

A husband and wife were on board at the time, but made it off safely.
