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.

HomePretoria Boiler Securement Project 2017

Pretoria Boiler Securement Project 2017









       




This year the GLSPS once again sponsored a Project in the Apostle Islands to support the Wisconsin Historical Society in keeping the Pretoria Shipwreck's Boiler near its wreckage. 

Selected active members of the GLSPS cruised the RV Preservation research vessel from Silver Bay Marina to the Outer Island of the Apostle Islands.  This was a continued project from 2016 when the GLSPS lifted and moved the boiler 300 feet back to the shipwreck.  This year 2017, we needed to secure the boiler. 

The boiler was attached to the bottom of the lake or near by the Pretoria Shipwreck by drilling eight holes into the bottom of the lake which is limestone.  We then used pinch bolts and epoxy to attached four 1/4 inch thick plates with two holes in each.  We then attached a chain to each bolted in plate and attached it to the boiler.  This will provide four attachment points to the boiler to help prevent the boiler from moving around in the future.

Both the 2016 and 2017  Projects were intense projects and many hours of planning for this type of underwater construction project.  It take many hours and days to locate equipment, design and build the underwater parts to secure the very large and heavy object.  The Pretoria Project was a very hard project for the GLSPS and Participants and we thank then for all their hard work, especially Tim Pranke and Jack Decker, which shared the Project Leaders position.  without there support and commitment to the project, it would not have taken place or be as successful as it was.

A special thanks goes out to both Jay Hanson and Phil Kerber for their use for the commercial dive equipment and rigging.  Ken Knutson for his expertise and on-board consulting on underwater construction and rigging advice.

The project was a success!  We still have a few things to do on the wreck and are planning another 2018 Pretoria Project.  Please check back to see what is next.  We will be opening the project up to other GLSPS Members.  Please check next years project schedule for more details and registration requirements.
