Re: Water in bilge after day on lake?
Sort of depends on what you are doing and how your boat drains. Also, sometimes water gets trapped in forward compartments of the boat and then drains aft as the boat is tilted up getting on plane, etc.
As mentioned, check for leaks, 'cuz those are what you want to address. Other sources of water are not as troublesome.
I always had water in the bilge on my 'old' boat, because that is where things drained into. The 'new' boat drains overboard, so we shall see. But having wooden boats as a kid, there was always water in the boat. So, I did not think too much of it with a fiberglass boat, as long as you know where the water comes from and that it is not an active leak.
