Do you really know what your policy will cover?
If we all inspected the hose clamps and the hoses on our boats before each time we left the slip and put the boat to bed for the weekend I guess we would not need insurance at all. But no matter how diligent we are, things do happen. Do you use a mirror to check the back of hose clamps to be sure they are not rusting through? So lets say that you ask your spouse "did you close all the seacocks"? "Of course I did, do you think I am stupid". Unfortunately one of the seacocks WAS left open. Now you go home the wind picks up a little at the marina, the boat is bouncing about in the slip and that hose clamp breaks, the hose is weakend under the old clamp and suddenly water starts coming into the boat. Since it is dark, no one at the marina knows that your boat is slowly taking on water. The bilge pump is running (but it is a few years old) and the batteries well they are a couple of years old also so they just can't keep up. As the water fills the boat and runs into your fuel tank, the fuel gets displaced by the water and suddenly you have a real disaster on your hands.Should this fall under the wear and tear exclusion? You knew that the bilge pump and batteries were old, You looked at the hose clamps at the begining of the year but maybe then that crack or rust in the clamp was not visible then. And further more you asked if the seacocks were closed anyway. All hypothetical yes, but is DOES happen. Do you know if your insurance company will cover the loss or not?
