Those blue and white umbrellas a lot of people use for summer time fishing.....do NOT float! They sink like a rock!

I have a very very obsessive compulsive (which is a nice way of saying anal) uncle who I borrowed his boat Saturday. I had to put him on the spot, because if I asked him ahead of time he would make up some story of how he was going to use it! Borrowed the boat and had the umbrella in the holder, cranked up the boat to go to the next top and forgot the umbrella was there. The umbrella flies out and I slow down and turn around, and that sucker was GONE. No more than 10 seconds had elapsed. So now I have to give him one of mine!
