A boat left tied at the dock will have water bumping it around and can lead to wear and tear. Many times, the bow of a boat gets damaged this way leading to expensive repairs. I just read this on a forum today (see it here):
“My boat crashed into this dock this weekend, and there are some serious gouges in the fiberglass on the bow. Gouged through the gel coat…I am worried about delamination of the fiberglass.”
Fortunately, with a boat lift, you will never have to worry about your boat coming untied or being damaged like this when you are not around.
In addition, you will avoid chances of your boat sinking due to severe storms, an unknown leak, a plug going bad, a failed bilge pump, or other issues. And, if your boat is not on the water, you won’t have to worry about whether your boat is safe at the dock or not.
