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.

The GLSPS Research Vessel the "RV Preservation
Preparation Weekends 
The Month of May was very busy for GLSPS Members,
Preparing our Research Vessel the RV Preservation
for the Upcoming 2015 Season of Diving Projects
RV Preservation 2015

It took a lot of dedicated effort from a few volunteers, but  the RV Preservation hit the water, early June 7 ready
for the 2015 Diving Projects.

If you have followed the TO DO list as to what we were planing to perform on the boat to make ready for the upcoming season, you would have noted items being checked-off each weekend.  We feel good about what was accomplished by a few talented members.
Launch weekend went quite well!  We have a few minor details to finish.                                                                                                                                           

The weather for this Year's "Membership Appreciation Boat Cruise and BBQ"
was amazing.  The "PRES" hit the water in the morning Sunday June 7, 2015.  While a couple of us took it out for a short shake down cruise, the rest set up canopies and tables and set up for the BBQ.

The food was great and the Sun made the cruise spectacular!!!!!!! 
Those who didn't attend, missed an awesome time on the water with the Duluth Harbor cruise and a trip out to the "WILSON"!!!  It was the same date "June 7" as to when the WILSON sank in 1902. (113 years ago). We all gave her a solute and a tip of our hats.
If you have any questions about the event, please contact Ken Knutson.  His contact information is below.
We hope to see some talented and new faces this year.

See you on the "RV Preservation"

Closing Report
Dedicated GLSPS members worked long hard weekends to Prepare our Research Vessel the RV Preservation for the Upcoming 2015 Season of Diving Projects  

Now the RV Preservation is mostly complete (except for a few minor tasks) and is ready for the first project of the year.
This year we had quite a list of tasks to complete including four huge tasks that took most of the weekends to complete.
Here is the list of the largest tasks completed,
1. Removed, rebuilt and reinstalled port transmission.
2. Removed both port and starboard side transmission to prop shaft couplers to rebuild over winter
3. Port side Lasdrop dry seal coupler to totally rebuild and replace main seal and install back up seal.
4. Removed starboard side prop shaft to check for straightness.  The prop shaft was OK the coupler was also rebuilt like the port side.
5. Lapped both props to shaft to make sure mating surfaces were in full contact with prop shafts and added new brass keys washers and cotter pins.
6. Rebuild Lasdrop dry seal water coupler and installed the main and backup seals.
The above repairs took the lions share of the weekends.  Please check the list on the event page to see what else we did to the vessel to make ready for the season.
Here is the link to the last work weekend and the most current tasks list,
One thing on the wants but not needs list was also completed thanks to Ken Knutson.  Ken installed the hot water heater.  The heater has two ways to heat up the water.  One is from electrical when we are at shore and plugged in and the other is from one of the engines.  We finally have hot water coming from our sink in the galley!  Thank you again Ken!! (CAUTION - AFTER RUNNING STARBOARD ENGINE, WATER MAY BE "VERY, VERY HOT"!!!!!!)
After a late launch and short shake down cruise by Ken Knutson, Tim Pranke and Dean Soderbeck, and the rebuilt transmission had it's final adjustments, Ken gave it the OK to give the Members a ride to the Duluth Harbor and back to Spirit Lake Marina.
Phil Kerber fired up the BBQ and with the assistance of Craig and Kari David, fed everyone a great meal before we departed at 2:30 PM for a 2 and one half hour cruise.  The members really enjoyed the the BBQ and cruise to the harbor.  Everyone one was so relaxed, many of them fell asleep! 2015 RV Preservation Appreciation Day & BBQ
Thank you again to all that volunteered their time and support to prepare the RV Preservation for the season of diving projects.  We all take pride in making sure the boat is maintained properly, be reliable and mainly comfortable for those that participate in the GLSPS Projects aboard the boat.
Here is a list of volunteers that helped part of and or all of the weekends:
1. Ken Knutson (Boat Chairman, 5 weekends and two times during the week)
2. Tim Pranke (Helped all 6 weekends including the launch weekend).
3. Jim Christenson (Helped all 6 Weekends)
4. Phil Kerber (Helped three weekends including the launch weekend BBQ)
5. Joe Musial (One weekend)
6. Steve Daniel (one weekend)
7. Bob Nelson (One Weekend)
8. Dean Soderbeck (One Weekend)
If it wasn't for the above volunteers taking their personal time to prepare the boat for the season, the boat would most likely still be in dry dock and wouldn't have launched on time for the 9th year in a row!!!
Thank you all once again!!
