Small isolated dock structure with no visible parking or support facilities in a natural coastal setting.
Bois Blanc Island Marina occupies a sheltered position on Bois Blanc Island in Michigan’s Straits of Mackinac. The facility fronts the clear, open waters of northern Lake Huron, where the lake meets the passage between Lakes Michigan and Huron. It accommodates recreational boaters seeking access to Great Lakes cruising, fishing, and island-to-island travel.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
