Inland Waterways, Duluth MN

Most recent update: March 22, 2020.


This shipyard was developed to build sub chasers, but only built four before folding.  Did they build anything else?  If anyone can provide any info please e-mail me at timcolton@aol.com   The yard was at 1000 Minnesota Avenue, where the Park Point Marina is today, immediately north of the Coast Guard station.
