moved guide pole??

I cannot figure it out...my boat just would not seem to go on the trailer right so i backed it back down and tried to realign. still rested on the pole. i then looked closer and noticed that the guide pole was moved in a good 6 inches. you could see the dust line still. i pulled the screw and moved it and could see the original screw hole but it did not seem to have any scraping on the top like it was hit. it was almost like someone moved it. has this ever happened to anyone?

i am stumped.

I bet somebody hit your trailer while it was parked. I just found a new rub mark on my Bronco that I think came the same way.
