The GLSPS Prepares the RV Preservation for another season of Projects

 | Published on 11/10/2013

The GLSPS Prepares the RV Preservation for another year of dive projects

The GLSPS sets aside two to three weekends to prepare the Society’s Research Vessel for a worry free season of boat operations.

Every spring we perform all the regular maintenance such as fluid and filter changes, lubrication areas, fuel system treatments and engines cooling systems including all electrical testing aboard the vessel.

We touch up any cosmetic issue that may occur over the winter season or from the previous season of using the boat for our projects.

This year we added a new sonar / depth sounder to the lineup of electronics aboard the vessel.    The current depth sounder was not working properly and it needed replacement.

After all the above repairs and maintenance are performed, we schedule the boat for launch the first weekend of June., which is Saturday, June 1, 2013.  After the launch, we perform a shakedown cruise up and down the St Louis River to make sure all boat equipment is working great and to make sure the vessel is safe for the upcoming season of cruising and diving on projects.  The afternoon is set aside for a Captains training session.  All Operators and crew are required to take this training every year or, they are not allowed to pilot the vessel that year.

Sunday that same weekend the GLSPS invites all members to join us for a cruise on the St Louis River and Duluth / Superior Harbors.  After the cruise in the morning, the GLSPS has a BBQ event for all the members to enjoy.  Unfortunately many of the members don’t take advantage of this event and never see what the GLSPS active members are proud of.  More members should join us to reap the benefits of being a GLSPS Member.
A good time was had by those that joined us!
The next weekend the boat is cruised up the north shore of Lake Superior to be docked at the Silver bay Marina.  The GLSPS Board of Directors have voted to keep the boat docked at this marina to help keep the cost of fuel down from having to cruise the boat from Duluth for every project and to save many hours of time cruising the boat up to this area for our projects.  Most of our seasonal projects are located in this area.
If you are interested in being part of the RV Preservation Boat Crew and are interested in helping us keep the research vessel alive, please let us know by contacting Ken Knutson or Phil Kerber by either email or phone.  There contact information is in the “Contact Us” field on the left side menu bar of the GLSPS website.
We hope to see you volunteering to help us aboard the RV Preservation sometime soon.
Thank you for your support.
