Milwaukee Commercial Marine Market

Milwaukee combines commercial shipping, Great Lakes cruising, charter operations and recreational marine activity within one harbor market.

Port Milwaukee controls vessel berth assignments at its commercial facilities, while its 2026 tariff identifies commercial workboats and specialized port equipment available for operations.

At the recreational-commercial interface, McKinley Marina contains 655 slips and supports fishing, sailing and recreational charter businesses.

Together, these operations create potential survey demand from:

• Commercial vessel owners

• Charter operators

• Fishing captains

• Passenger-vessel operators

• Workboat owners

• Prospective vessel buyers

• Insurance carriers

• Lenders

• Attorneys

• Marine businesses

Great Lakes Cruise Vessel Activity

Milwaukee has also become increasingly active in Great Lakes passenger cruising.

Port Milwaukee reported that American Cruise Lines planned six Milwaukee calls during 2026 with the U.S.-flagged American Patriot, a 130-passenger vessel, in addition to Milwaukee's established Great Lakes cruise activity.

This further reinforces Milwaukee as a genuine commercial-passenger-vessel market rather than simply a recreational boating location.

Milwaukee Charter Fishing Market

Charter fishing represents another commercially relevant marine sector.

McKinley Marina maintains a dedicated charter offering and currently identifies numerous commercial fishing-charter operators, along with sailing and recreational charters.

Commercial charter boats can generate survey requirements involving:

• Pre-purchase transactions

• Insurance

• Financing

• Condition & Value

• Vessel appraisal

• Damage claims

• Machinery condition

• Safety equipment

• Commercial operation
