It’s just not boat to boat collisions, there are many that don’t pay attention to shoreline activity. On a hot summer day we swim off the end of our dock, umbrella is up, grandkids playing etc. etc. My seasonal neighbour from a few doors down decides to take his kids out tubing. No problem, but he thens proceeds to move closer and closer to the area that we are swimming in until for our own safety, we all have to exit the water while the continues to buzz past the end of our dock repeatedly. It’s an 18 thousand acre lake. Next time they are out, I’m going down to have a word with him. Just plain ignorance.
