A lot of good advice above. I would just encourage you to take a basic boating class to learn about the rules of the road, safety etc. There is a US Power Squadron in Sandusky and Port Clinton that offer these classes. I'm sure there are experienced boaters in these classes who would be willing to spend a few hours with you on your boat to help you get the hang of operating and docking your boat. Also, do you have charts of Sandusky Bay and the lake? How about a depth finder? With those two you should be able to navigate your way without running aground.
