Lot's of good advice here for sure. I can share that the insurance thing is a very big deal. Two issues, we're on a 26 year old boat - that limited the number of carriers severely. Next, even though I've had 50+ years boating the Great Lakes, because I never owned a large vessel - their requirements were very strict about captain training. I got lucky that we were referred to a quality guy who was very patient and did an awesome job with me and the admiral.
I would also suggest the Power Squadron training classes. They are cheap or free depending on the local unit. You will get exposed to a lot of the challenges a large boat owner will have to deal with, including safety and navigation. Well worth the time.
