A couple of years ago I took my kids sailing on my Miracle for a couple of hours. It was only when I got back and almost derigged that I noticed a couple of hornets coming out of the front beam. There was a nest in there. The kids had been playing on the trapeze and the old shock cord had snapped and flipped around in the beam. I don't know why they didn't come out while rigging or sailing or shock cords flailing around. They sure came out and were looking for something to sting when I sprayed insecticide in there. I also discovered a nest just inside the port hole, about an inch from where I put my fingers to tip the boat bows down. Once again no reaction.
