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.

GLSPS Fun Dive Project

(R/V Preservation docked at Silver Bay Marina Slip # D 17)

Saturday and or Sunday, July 8 - 9, 2017

This event is put together to get our non active GLSPS Members together.  Members can also see first hand how we do things on-board the vessel which we make as safe and organized as possible.  This is NOT a cattle boat like you would see with some Charters.  It is an excellent way to join us and have the opportunity to be more active in the Society.  What ever level you decide to be at, there is a place for you as a active member.  We are always striving to gain new members and especially active members that like to dive and participate in the projects the GLSPS provides.

Diving off the GLSPS Research vessel the RV Preservation, is one of the benefits of being a member.  This is without a doubt the largest benefit the members have and can enjoy both divers and NON divers!
The event fills up fast because of the popularity so please don't hesitate to register ASAP. 


Please note: This schedule and dive locations could change at any time due to weather, lake conditions or any other unforeseen issues.

Closing Report:

GLSPS Fun Dives with Air Down There Scuba 2017


Every year the GLSPS invites dive shops to dive with the GLSPS on-board their Research Vessel the RV Preservation.  It is our way to thank the Dive shops for participating in the UMSAT Show and as a partnership in the diving industry.  The last two years only one dive shop has stepped up to take advantage of the GLSPS invite.  This year for the Fun Dives Air Down There Scuba joined the GLSPS again to enjoy shipwreck diving along the North Shore of Lake Superior on-board the RV Preservation.  


As usual, we had a great time diving the shipwrecks with ADT Scuba’s group of divers.  Before each dive we present a detailed history of each shipwreck site, a detailed description of the site using underwater drawings of the wreck by fellow colleagues of the GLSPS.  Then we dive with the participants to give them a personal underwater tour of the wrecks.   We know the shipwrecks very well since we Monitor and Document them every year.   There has been a rumor that there is much more wreckage to see on the Madeira than most know??  Maybe?  You will have to join us for a Fun Dive to find out!     


If you are a dive shop and are interested in joining us on a GLSPS sponsored Fun Dive, please contact the GLSPS at to learn more about the event and process.  You can also visit our website at for more information about the Fun Dives and the schedule of events calendar for the summer season of projects.  The calendar is typically available by the end of February each year.  Please feel free to check the Calendar after that.


Please join us for a few fun dives and projects this coming year!
