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.

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.

HomeWreck Buoys

Shipwreck Mooring Buoys

The GLSPS maintains mooring buoys for various shipwrecks along the North Shore of Lake Superior with the help of several local diving organizations, stores, and individuals.
Mooring buoys on shipwrecks serve several purposes:
  • Improve diver access to the shipwrecks by making the wrecks easier to find.
  • Improve the safety of the dives by insuring that divers have a descent and ascent line that won't disappear like an anchor line can if the anchor breaks loose.
  • Eliminate potential anchor damage to the shipwreck which can happen over time as many groups of divers have to grapple the wreck with their anchors.
The GLSPS performs the process of receiving authorization from the US Coast Guard, Minnesota DNR and Port Authority.  We obtain the funding for the buoys partially from membership dues, Grants, DNR and PADI Aware Foundation.  Membership dues pay for most of the mooring attachment hardware, and installing the mooring buoys. 

We then attempt to locate a partner who has a regular presence on the shipwreck sites to do the annual installation and removal of the buoys and to monitor their condition over the season.  Currently we do not have any sponsors for any of the buoys.  We are seeking any group such as Scuba Clubs or Dive Shops to sponsor one or possibly more buoys.  Please let us know if you would like to sponsor our shipwreck mooring buoy program by going to the "Contacts" section of this website.

We have also assisted the Wisconsin Underwater Archeology Association in placing mooring blocks and buoys on the shipwrecks of the Pretoria and the Sevona located in the Apostle Islands.
