Jay Hanson from Superior Scuba Charters and 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.

GLSPS Programs

GLSPS is committed to preserving our deteriorating historic shipwrecks. Like so many problems in today's society, there is no single answer to how to preserve shipwrecks. For that reason, GLSPS is attacking the problem on all fronts. Our motto "From Prevention to Preservation" identifies our philosophy. We educate the public to appreciate these historic treasures in our shipwreck shows and shipwreck displays, and promote the dive ethic "take only pictures, leave only bubbles." We are developing a Low Impact Shipwreck Diving Class to teach divers to hone skills that minimize damage to the sites they visit. Our mooring buoy program not only makes visiting these sites safer and easier, but also minimizes damage caused by boats anchoring on the site.

Intentionally sinking a ship creates an educational and recreational diving attraction which tends to lure divers away from more historic and fragile shipwreck sites, lessening the traffic and minimizing damage to these sites. The traditional way to preserve shipwreck sites is to preserve the information in the site by documenting the site in drawings and photographs. We do that also, but GLSPS has taken the next step, which is to actually repair damage and stabilize these deteriorating sites. Our monitoring program keeps track of changes to the sites over time so we can better understand the causes of this deterioration. We also put back certain artifacts that were removed by divers in the years when it was popular to do so.

Historic shipwrecks are a non-renewable resource. Using them and preserving them do not have to be contradicting concepts, but only if we are responsible to put back more than we take. Join us in preserving shipwrecks.  Here is a link to the detailed  GLSPS 2017 Organizational Structure Outline 1-2017
