If you don't carry insurance you are open to a lawsuit that could possibly take away your lake house and every house you own. You leave yourself open to that. You may be able to notify the insurance company when you plan to use it and save some money.
Keep in mind, anything can happen in this world. A hiker may be swimming, a parachuter may be off course, a plane may crash and your trying to save people in your boat, and someone gets hurt getting in, or run over, or any number or terrible things that could happen. For the Little amount of money it cost to insure a seasonal boat it is well worth it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
