Three boats were destroyed and a fourth damaged at a Macomb County marina by an owner preparing his vessel for winter storage.
The Detroit News and The Macomb Daily report that shrink wrap was being applied to one boat Sunday afternoon when the fire started at the marina in Chesterfield Township.
Fire Capt. Richard Schroeder says each of the boats were 30 feet and longer. Damage is estimated at $500,000.
The marina is northeast of Detroit.
Firefighters from nearby Selfridge Air National Guard Base pumped about 200 gallons of foam to smother the blaze and soak up spilled fuel.
Shrink wrap is a thin, polymer cover that protects boats from the weather during winter months.
Schroeder tells The Macomb Daily that when shrinkwrapping "they heat the plastic" with a torch.
