Come on in Gary.  I have shoulders broad enough for all of you
 
Bob

That's what I like about this forum.  I always remove the hull and then have trouble holding it to draw the water line.  Thanks Michael.
 
 
Although Nils' boats are bigger the scale is smaller, so I know it can be done.  I have the material, so I might try.

So much detail in such a small space.  The funnels are great.
 
Bob

From four simple tubes and a few small pieces, comes such beauty.  Well done.

I finally got a start on the Mariefred.   The drawings I received from the museum in Stockholm were the best drawings I have ever received.  When I get drawings of a boat the first thing I do is scan them into my computer and open them in an ancient copy of AutoCad.   Then I check length, breadth and height as though I were designing her.  Usually there are errors that must be corrected.  But these drawings lined up and were correct.  When designing a boat the designer draws one side of each bulkhead these then have to be redrawn and each one needs to be mirrored to make a full width bulkhead.  These are then transferred to and cut out of wood sheet and mounted on a board.  That is where I am at the moment.
Bob

Well I see I'm going to have to be careful with this build.  There are too many people who have seen and/or been on her.  Well, at least when I get confused there will be people who can hopefully answer my questions.
 
Bob

Russ, I believe the main parts of the boat are wood.  But in some pictures such as one picture of the bow the spray guard on top of the rail is dented so it is metal. 
Welcome aboard, Michael and Nils.  I hope this turns out to be another ‘fun build”.
This is a picture dated 1903.  I will try to build to this time.

Mariefred
The coal-fired steamship Mariefred was built in 1903 for the trade-Enhörna Stockholm-Mariefred. She has sailed under the same name and with the same steam engine ever since.  The vessel has been owned by the same shipping company, Gripsholms-Mariefred Ångfartygs AB since 1905. All this makes Mariefred one of the worldwide unique ships and an indispensable part of Sweden's cultural heritage! 
Built at South wharf in Stockholm in 1903. Length 32.84 m, width 6.33 m. Coal-fired steam boiler.  Speed 10 knots.  230 passengers.
 
 

Part 2 – Research
 
The HAER documentation contains 8 pages of drawings showing various views of Kathryn, including many details of the interior construction.  Since I plan to build the model as a true plank-on-frame with all (or most) interior fittings, these drawings are an excellent resource.  Besides depicting the construction details these drawings also contain descriptions and measurements of many of the details.  However, I found during the drafting work that these drawings have a few errors – I’ll cover that in a later post.
 
The HAER documentation also includes the detailed description of Kathryn that was submitted for the National Historic Landmark nomination, and this description is a very valuable supplement to the HAER drawings.
 
The HAER drawings are available as TIFF files (much better details than JPG), which were loaded into my CAD program and then scaled to actual dimensions.  Each drawing contained a scale that made this easy to do.  Where the documentation did not contain measurements for a component, it was usually easy to determine the measurements based on the scaled drawings.
 
I collected the measurements in a separate document for easy reference.  That document is attached.
 
            Kathryn Specifications and Dimensions.pdf
 
In addition to the HAER documentation the article by Ben Lankford, found in the Nautical Research Journal published in June 1983, contains many useful descriptions and also a table comparing the sizes of different components from various sized Skipjacks.  Kathryn is a large Skipjack, and in some cases it was possible to estimate the size of a component by comparing it to the size of the same component in the various smaller Skipjacks.  Attached is a PDF of the comparison table.
 
            Skipjack Size Comparisons.pdf
 
Photos of the recent reconstruction efforts are available online, and these were invaluable for determining the configuration of several components.  Photos can be found at SavingWhatMatters.com, and at the Washington University web site at www.washcoll.edu/live/galleries/2508-restoring-skipjack-kathryn
 
There is also an interesting video on YouTube showing the Kathryn dredging for oysters (the video was taken before the recent rebuild).

In addition to the above resources, the following books contributed needed information:
            American Small Sailing Craft, by Howard Chapelle
            Notes on Chesapeake Bay Skipjacks, by Howard Chapelle
            Chesapeake Bay Sailing Craft, by Robert H. Burgess
            Working Skipjacks of Deal Island, by Brice N. Stump
 
I also have a couple of good friends who live in the Chesapeake Bay area, are very knowledgeable about bay craft in general, and who are excellent modelers who focus on the boats of the Bay area.  Through these good friends I have been able to go aboard Kathryn after her recent rebuild and have also been introduced to individuals who were instrumental in the rebuild efforts.
 
 

Other than finishing, I'm pretty much done with the deck. Work moves to inside the hull - electronics.  First up, assembling a keel with the propeller shaft. The keel is 4 layers of plywood. The 2 inner layers are each made up of 2 pieces.
 

 
The space in between the 2 pieces leaves a groove for the propeller shaft sleeve. I had really hoped to take pix of a step by step but it quickly became apparent that I would be busy trying to hold and glue all the pieces together and try to keep it all clean. Well I failed on the last part. The process was the usual clearcoat then thick stuff. The problem was in doing layers, excess epoxy is squishing out the edges getting all over my hands and the parts. So I'm trying to wipe that off, which moves the parts around and sliding them back into position squishes more epoxy out. Glad I wore gloves.
 
Finally, I decided to just leave it alone. I was not going to get all the epoxy off. But hey, I've got a cool belt sander that should take it all off and anyways I think I'll paint the keel.
 

 

 

 
You can see the mess. But it's done.

There was no forced air air conditioning in those days, so they needed all the vents, and if there were an electric fan all the better.

Thanks for showing and telling about each step.  Well done.

TB, you're right. The waterline is the same height from the building board on each station and the step at the deck makes it easy to bend that first plank to the correct shape.
 
Patrick, thanks for the encouragement.  But I'm not sure about, "flying".
 
Angarfather,  it is nice to have you and other, who have seen the Mariefred, along for this build.  If any of you see me missing something don't hesitate to point it out.

Frank, I gota watch this one.  I've always liked the skipjacks.
