I certainly agree and was going to post that same advice.For peace of mind and heart get a towing policy! Boat U S or Seatow , your choice. Any tow you need will more than pay the premium
Personally, I would not set out on a thousand mile cruise in a new to me boat without a couple of short cruises first. You want to get familiar with the boat and correct any problems you might have, but on another level, you might discover that you overlooked something like pots and pans for cooking, no sheets and blankets, no dinnerware or knives and forks, etc., no toilet paper. Toothbrushes and toothpaste? Little things for sure but hard to resolve in the middle of nowhere.
Do you have charts and/or a chart plotter covering the area you plan to cruise? Do you have cruising guides listing marinas and fuel stops? Or Internet access so you can use on-line services to find this info?
