Chris and his team were great to work with! I booked with them to celebrate a birthday and they were very accommodating, communicative, and made the experience so fun!

I’m a serial entrepreneur. I’ve started and built multiple companies across different disciplines from the ground up whenever I felt that the existing landscape didn’t really address what the consumer wanted. All were built upon the premise that the “Customer is Always Right.“ We are the longest running “small boat” privately held company in the Chicago area. My goal when starting this company was to take any negative that I had ever encountered and to make sure it would never happen to you when you Chartered with us. We aren’t the biggest but we are the BEST and most passionate about what we do. “Nautilus Lake Michigan” is the result of running trips for the last 25 years and realizing there wasn’t a boat that satisfied the needs of groups from 12-44 passengers. There wasn’t a boat that was already being manufactured so we built our own Custom boat based upon what people were asking for and needed to make a truly unforgettable Charter. Come out with us and become a part of our family!!
You’ll get helpful information for your departure after your booking is confirmed.

Departure Location
Free cancellation up to 14 days before your trip.
Weather related cancellations will be handled on an individual basis. We will discuss any extenuating circumstances that might lead a client into canceling within the 14 Day period. Customer receives full refund if Captain feels it is unsafe to go out on the trip. This rarely happens because of our location being behind the Chicago Breakwall. If the client is late we will do our best to give you the entire time you have paid for if there is not another Charter booked after you. If a mechanical issue forces us to cancel your trip, we reserve the right to book you with another operator. No Drugs or Firearms are permitted onboard. If the Captain feels anyone in your group to be a safety issue we will bring that person back to the harbor. After removing that passenger, we will continue your Charter for any remaining time. If you choose to not continue, there will be no refund issued for unused time.
