I just got back from dardanelle, I was a marshal at this event and heard it was a problem with the charger. He went to plug in his charger Wednesday night and it wouldn't work so he went to walmart and bought a cheap charger. I'm not sure if it was a trickle charger or not but he said he just plugged it in and went inside and to bed. The hotel called him in the middle of the night and told him he should move his boat as one was on fire in the parking lot. He said he went out and it was his boat on fire. During the fog delay Friday I heard his brother saying he didn't think it was vandalism just a bad or wrong charger.
