This page watches the same safety-gated Detroit Outdoors engine for fresh named commercial-vessel AIS reports close enough to create a short-lived riverfront viewing opportunity.
The live evidence is loading now.
Updating…
The Detroit engine only creates this window when a named commercial vessel has a recent AIS position near the Detroit Riverfront. The shared Great Lakes tracker accepts reports no older than 30 minutes, and this Detroit signal looks within roughly 12 miles of the riverfront reference point.
AIS is informational, not a passage schedule. A vessel can slow, turn, stop reporting or pass before you arrive.
The Detroit Riverwalk is a public riverfront corridor with direct Detroit River views and nearly five miles of connected walking space. Exact visibility depends on the vessel's position and your segment of the riverfront.
Open the live ship map immediately before leaving. That map, not this page, is the final position check.
The page does not fill the space with a generic riverfront suggestion when the live ship signal is absent.
Use this page to answer the first question: is there something worth going to see? Then use the Great Lakes Ship Tracker for the current vessel position before committing to the trip.
