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.

RV Preservation on the North Shore
Closing Report

September 12, 13, 2015


Crew: Phil Kerber (Captain), Jack Decker (Event Leader), Jim Christiansen, Bill Wallace, Vinnie Cobbs, Ken Merryman


This is a continuation of the GLSPS Board of Directors desire to encourage members that haven’t participated for a while, or not at all, to participate and meet other members.  To that end, we had brand new member Vinnie Cobbs on board.  Vinnie celebrated his 50th Open Water dive on our second dive on the Hesper, that Sunday.


We did 2 dives on the Madeira on Saturday.  The big Lake had building waves, so the ride was a bit bouncy.  Ken and Jim were trying to capture some video for new 3D film software Ken is experimenting with.  Visibility was fine for diving, but, not quite what Ken wanted for this.


On Sunday, we made a quick trip out and around the Silver Bay Marina breakwater to the wreck of the Hesper.  We did 2 dives here.  Ken looked to get video here, as well, but, the waves had the visibility stirred up too much to even attempt video.


Breakfast and lunch both days on board kept our crew fueled.  With a nice relaxing supper in town Saturday night, the crew was happy, as well.

Fun Dive on the North Shore
Closing Report
September 13 -14, 2014


The GLSPS decided to have some “fun” events, events that don’t have a particular project. These events are to get members that haven’t participated or been on the R/V Preservation, to do so, or to participate in a more involved role. Without a specific project to complete, the emphasis is on getting to know other members and diving.


This event had 7 participants: 6 divers and 1 non-diver.  The divers were Luke Flacksbarth, Mike Gatzke, Phil Kerber, Mac McClure, Tim Pranke, and Jack Decker; the non-diver was Brigette Gatzke.  Phil graciously provided his services as Captain.  Tim clocked some time behind the wheel towards his Captains License.  Jack served as “Event Leader.”


The boat was docked at Silver Bay Marina.  We planned to dive the wrecks of the Madeira and the Hesper and, possibly, some shoreline features. Weather permitting, of course.


Some of us were hoping to dive the Hesper Friday evening, but, ran out of time by the time we all arrived and got the boat ready.


Building waves were forecast for Saturday, so we got up early and headed to the Madeira.  We all got one dive in and decided to head back to the dock before the waves made traveling too uncomfortable.  We did some inspecting of a large piece of steel inside the stern section that is rather loose.  It will need some attention, either to secure it to the wreck or bring it down.  The afternoon was spent relaxing on the boat and talking with other divers and boaters at the marina.


Fellow members Steve Daniel and Jay Hanson joined us for the evening.  After supper at a local establishment, Jay and his family treated us to a campfire on shore at the marina.


Sunday saw high waves, again.  We motored out and around the marina’s break water to the calm waters above the Hesper.  Not everyone chose to dive, but, those that did got one dive in.  After the diving, Tim drove the Preservation on a “tourist trip” to see an ore carrier up close.  The ship came in to port while we were diving.


We had several “first timers” on board and a first time event leader.  Even though the weather didn’t quite cooperate, the camaraderie and amenities on board the R/V Preservation were excellent.  As a first time leader, I enjoyed getting to know the GLSPS procedures better.  My pancakes might need some improvement, however.  If my pancakes can be overlooked, I plan on volunteering to lead some more events.

Please join us next year (2015) for the GLSPS Fun Dives off the RV Preservation along the North Shore.  We hope to see some new faces joining us.

Closing Report
The above Project was canceled because of the lack of interest.  If members would like to join us on any fun dives off of the RV Preservation, please register in advance or when they become available so the dive doesn't get canceled like the above fun dive.
It's hard to believe members (and their dive buddies wouldn't jump at the chance to dive off a boat along the North Shore for next to free, (except for the gas expense driving up the North Shore).
