interesting, looks like its on the outside. If it were the other way, pointing down I would think a tie down for a winter cover but its not. You got me, lol.
I thought it might be some type of fender clip but thought it would not be substantial enough for an over night fender. But a "light duty" makes sense. I don't suppose anybody knows what the ball type attachment is called so I can look into ordering some? Thanks for your information.
Yep its for a fender. I was wondering the same thing for our boat until one day we found a freely floating fender with this little circle thing and we realized it fit into it!
