Congrats. on your purchase. I am no expert, but, I would advise getting as good of cover as you can afford. Maybe as part of your boat purchase deal you can get one at a discount or something. Not only does it help protect your boat and deter would be pilferage, if it is a good fit you will actually get better gas mileage when towing. At least that has been my experience. Hope this helps, or that you receive some other repsonses that are beneficial. Again congrats on your purchase. Don't worry, the nerves will settle down about the time to winterize it.
