Jay Hanson from North Shore Scenic Cruises has helped the GLSPS on many projects. Jay has many years of experience as a Captain, dive shop owner, dive instructor and commercial diver.

Jay has taken a different path for the past few years and his scuba charters are no longer available. However, in 2012, Jay purchased the Wenonah which was previously used to transport people from Grand Portage, MN to Isle Royale, MI. He now offers day cruises on the North Shore of Lake Superior and is docked at the Silver Bay, MN Marina.

For the last two years the Wenonah has been laid up in dry dock to replace the entire steel bottom of the boat in order to pass the Coast Guard Safety Inspection. 
The Wenonah will hopefully be ready for service in 2020.

If you are interested in booking a 2 hour - day charter cruise on the North Shore of Lake Superior, please click on the logo above for information on joining him and his staff on a north shore day cruise.

HomeEssex Mast Restoration Project

USS Essex Mast

USS Essex History

Camp Perry, Port Clinton, Ohio

The USS Essex was built in 1874. She was designed by Donald McKay, the famous clipper shipbuilder. In 1917, she was transferred to the Duluth Naval Station and was used for a receiving ship for the Naval Reserve until sometime in the 1930s. She was decommissioned, burned, and scuttled off Park Point.

Many artifacts were removed including a mast that ended up at Camp Perry, Ohio, where it was used as a flagpole for many years.

Several years ago, a tornado blew down the mast and it was stored inside a warehouse until its status could be determined.

The PIB committee of the GLSPS has made arrangements to bring a section of the mast back to Minnesota and is working with the Minnesota Historical Society, the Lake Superior Maritime Visitor Center, and the City of Duluth to determine to best way to preserve and display the mast section. A plaque will be included that tells the history of the USS Essex.

USS Essex Mast Section Returns to Minnesota

Last October, several GLSPS members went to Camp Perry, Ohio, to bring back the mast section.

The Great Lakes Maritime Visitor Center has agreed to display the metal bands along with some of the small wooden pieces. GLSPS is working with the City of Duluth to determine an appropriate display of the mast section at a suitable location on Park Point.

The Minnesota Historical Society has offered assistance in recommending preservation techniques for the mast section.

Tom Brueshaber and Ken Knutson (GLSPS Treasurer) tighten the straps holding down the mast section before its journey back to Minnesota. The mast section is now in storage until the historical marker can be created at Duluth, Minnesota.

USS Essex Mast Parts Donated to LSMVC

Smaller parts of the USS Essex mast section have been donated to the Lake Superior Maritime Visitor Center in Duluth, Minnesota. The mast stay ring, band, and other parts will be housed in a future display at the Visitor Center.

Iron ring that held mast stays, iron band that held topmast to the main mast, and iron bolt, brass curved plate, iron eyebolt and hinge, brass pulley, wooden mast tip and two pieces of the mast.
