Re: Can I make this trip as a novice
Hi abrahamx, I've never sailed that area, but a quick look at the charts says you'll likely be marina-hopping, except perhaps the first night in Saginaw Bay. Plan your jumps and listen for weather. As a Great Lakes sailor you know how quickly things can develop and change.
Good advice from the others. Leave the schedules at home, and don't push it too hard. Nothing wrong with 15-20 mile days. I'd spend a few days sailing around the bay before heading off. You'll learn your new boat, and hopefully break anything that was about to break before you start the journey.
One more thing, keep a close eye on any freighter traffic, and stay out of the lanes. Not sure what it's like in Saginaw Bay, but you'll get into the thick of things as get get closer to the St. Clair River mouth.
Why go fast, when you can go slow.
