  • Changing insurance companies

  • Financing or refinancing a vessel

Chain O’Lakes Boating Market

The Chain O’Lakes is a particularly valuable survey market because it consists of multiple connected recreational waterways rather than a single isolated lake.

Illinois DNR identifies Fox, Grass, Pistakee, Channel, Petite, Catherine, Marie, Bluff and other lakes as part of the interconnected Chain O’Lakes system.

That creates a large concentration of:

  • Recreational powerboats

  • Pontoons and tritoons

  • Fishing vessels

  • Cruisers

  • Performance boats

  • Personal and family watercraft

  • Marina and seasonal-storage facilities

Fox Lake itself also maintains a substantial marine-business presence, including Chain O’Lakes Marina and other boating-related businesses.

  • In the water

  • On trailers

  • On blocks or stands

  • In indoor storage

  • In outdoor storage

  • At marinas or dealerships

The vessel’s location and accessibility can affect what portions of the boat can be inspected.

Depending upon the survey type and scope, the report may include:
