First and foremost, staff at the Marina are awesome! Pat and Phylis as well as Gina in the past have been a tremendous help. Marina is very well kept with great security. Unfortunately, Chicago Marinas are hard to navigate for transient boaters that enjoy launching and staying for a weekend. Launching on 31st street is near impossible (can only launch from this marina Monday thru Friday...and better not plan on leaving Sunday!)In addition to taking the trailer to the Marshalling yard if we plan on spending the weekend on the boat. We had to launch from Burnham harbor to get to the Marina. The Marshalling yard is a good 10 minute walk from the marina. The walk to the marshalling yard from the 31st Marina can be scary, especially as you get near the yard as there is very poor visibility from that street. I was happy to see a patrol car parked near the entrance to the Marshalling yard when I went there this weekend, If it werent for these challanges, we would give the harbor a perfect score. My family and I will continue to be customers to this Marina as the staff at the Marina have no control of the rules for the Chicago harbors. Hopefully the city hears the many concerns and helps somehow.
