We built a dock for the pond using a pontoon boat this summer. My question for you all is this, do I need to pull it out for winter? We live in Iowa and the pond will most definitely freeze. One friend of mine has the same setup and leaves it in all winter. Another pulls it out. I don’t have a trailer or an easy way to get the boat out of the water so it would be easiest to leave it in but I’m afraid of ruining it.
