For sure have tow insurance. I have Boat US also and even though I havent needed it yet Im glad to know its there when I do. I didnt have tow insurance on my last boat and the one time it broke down was luckily only a few hundred feet from the ramp. I cant imagine the bill if it would have happened earlier when we were twenty miles out. For no more than it costs get it! You also get discounts at West Marine and a magazine
