The story told is an employee was patching a section of shrink wrap on the motors of a boat below ours, one rack over, and the heat gun apparently ignited the cover underneath the wrap. Sketchy explanation since that boat had twin outboards and the cover was probably 4 feet away from where the patch work was being done. That and the fire apparently happened 20 minutes after the employee performed the work. 12 boats were destroyed with as many if not more damaged. After looking at the ones damaged, I'm glad ours was actually totaled.
