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.
