Many centuries watertransport was the fastest and most comfortable way of traveling on the coasts and along the big rivers in Europe. By towing with horses along the rivers and canals. By sail across the open waters.
 
The statenjacht was the Rolls Royce of this passenger ships. Used to move fx company executives or other VIPs from place to place to execute their jobs.
 
It was the time of the Barroque. So this ships were fitted out with most comfortable state cabins, bedrooms, kitchens, and last but not least magnificently decorated.
 
 
At first I had in mind to build the HMY Mary from 1670. Only her decorations and paintings were very complicated.
 
The Utrecht, however, seems to me a bit simpler decorated. Moreover, in the books of Seawatch books are very good plans of this ship.
 
I build the Utrecht in scale 1:36. As POF model. However, I'm doing the frames of10mm plywood. Since the frames are not seen through the planking, solid wood is too good for this job in my eyes.

The arrival of a long-awaited reference book through inter-library loan has helped to clarify some important design questions for this build, while forcing me to start over. The new book is Jerome Petsche’s  1974 “The Steamboat Bertrand: history, excavation, and architecture”, the official account and documentation of the National Park Service excavation of the wreck. I had expected this book to help me later on with obscure details, and so hadn’t worried about waiting for its arrival (having no idea when it would show up), as I trusted my purchased plans to be accurate enough for beginning basic hull construction. However, the more I’ve studied the plans, comparing them to other things I’ve read about the Bertrand and steamboat architecture in general, I’ve developed a few concerns. Petsche’s book has justified three of my concerns and shown me the proper way forward.
 
1)      Spacing of hull frames.  

The plans’ side view show twice as many horizontal floors as vertical futtocks (see above, left). This struck me as odd, because I’ve seen no other references to steamboats having this design, and the futtock spacing was twice as wide as dimensions listed as typical for steamboats of this era. My references say that frame assemblies generally varied between 13-15” apart, which is how the floors are drawn. And other examples of steamboat framing I’ve seen are very closely spaced.  Petsche’s more detailed architectural drawings (above, right), done directly from the wreck itself, clearly show floors AND futtocks always paired, and at a spacing just over 12”. Also see the overheard view, below. I don’t know why the plans omitted half the futtocks, but it appears that accuracy demands a full and closely spaced set of frames. I will have to think about what this means for a view into the completed hull.
 
2)      Shape of bow.

Riverboats of this era generally followed two bow designs: model and spoonbill. Model, the earlier version, came to a sharp point at the stem  much like a regular ship’s bow. Spoonbill, which became widely adopted in the 1970s, carried a much broader curve, which evolved with the need for upper river boats to slide up, over, and onto sandbars and river banks rather than slice through water. My plans show Bertrand with something much closer to a spoonbill bow (above, left), though she was built before their widespread adoption, and built originally for the Ohio River, where spoonbills wouldn’t have been necessary anyway. Sure enough, the Petsche plans clearly describe and show a much sharper model bow (above, right), with very different lines than my plans.
 
3)      Cant frames.

My plans don’t have an overhead view of the internal framing, but the side profile doesn’t show any cant frames in the bow, implying that the futtocks are perpendicular to the keelson all the way to the stem. This, too, struck me as odd, and the Petsche plans bear this out. They show cant frames beginning virtually at the beginning of the bow’s curve, with no beveled frames to be seen. This is an exciting discovery, because I think it will make the hull easier to build, and also gives me a more accurate frame of reference for getting started.
 
I suppose one moral to all this is, don’t get started until you’ve completed ALL your research. But I find that I learn by doing, and while I did quite a bit of pre-reading before starting this log, I also felt like getting started and figuring things out while underway. I use the same approach when building full-scale structures (I’ve built most of the outbuildings for my farm, including our dairy barn). When translating a 2-D plan into a 3-D model, there’s nothing like holding the actual timbers in your hands and seeing how your paper idea fits together in real life.
 
I’ve lost a bit of work that I will have to do over. But I’ve learned quite a bit, too, and don’t regret getting started. I didn’t expect my purchased plans to be so off in basic hull design, and had no idea when my deeper references would arrive. Getting started made me happy, gave me something to do and share, and produced an experience that I (and hopefully some of you) learned something from.
 
So no worries, and when next I can get back to the work bench, I’ll start anew on laying out the hull to my new, truly accurate plans’ design.
 
In the meantime, a question for the commentariat: 
 
Given the close spacing of the frames, and my stated desire to have the interior framing of the boat visible when completed, what's the best course of action? Do I leave out half the futtocks & floors on one side after all? Do I leave a big hole somewhere for viewing? Something else I haven't thought of yet? Ideas welcome.

Build log part 86
 
 
 
taking plans for positioning the ships boat, here dry fit trials.
There will be two spare topmast spars horizontal over the fore-ballustrade and the main gallows, on which the boat shall rest. The main stay-sail between the two masts is arranged and rigged in hight to enable free flying to either side without fouling the boat, and the hight between deck and the horizontal spare masts allows sufficient full hight crew`s move on the gun deck
 
 
Nils
 
 

 
the boat will be placed with a little assymetric offset to the port side I think
 
 

 
the spare topmasts here are only interim dummies....
 
 

 
the lowest stay-sail can swing free well above the boat
 
 

 
the boats bow in the background  peeping through belfry stool and the vertical lines
 
 

 
Hight for crew on gundeck is sufficient, even with hats on.....
 
 
 

Thanks Martin,
 
The shroud cleats are made quite simple, like I had shown earlier in this log. I thought about something in wood, but that would have been too prominent in this scale

Part 4
 
The decoration of the transom was a interesting area. First problem was the framing. I wasn't able to make it from wood. 
But the solution was to make it from 2mm soldering wire. In a vice I formed it into a fourcorner.
 
 

 

 
 
Some shots after painting the hull. I use distemper coulors. Tar = van Dyck brown  decorationareas = english red 
 
rails are black.  The frames of the transion and the decoration = leaf gold
 

 
 

 
 

 
 

 
 
 

 
 

 
 
 
 
 
 
 
 

Hello everyone
Thanks to all visitors of the workshop and all assessments with the like button.
 
At the moment is some slack in the shipyard – for this, I was working on another project, as you can see below - a new vehicle for ... ?!
 
@John, Dimitris, Nils, Patrick and Row
I am very pleased to welcome you in “Stavangers“ workshop regularly and I appreciate your nice feedback - thank you so much! 
 
@Lextin
It's good to know an other RC sailors aboard! – and thank you for all your likes. Again and again, I am pleased about your "Byzantium" workshop. I follow it with great interest.
 
@Nils
... Yes, the ability to climb hard at wind was one of the main demands of these rescue boats and definitely, an appropriately balanced lateral plan is one of the keys to the main characteristics of a sail boat (see below: Derivation of CLR).
 
In case of “Stavanger“, the location of CLR is about 12% (measured in relation to the length of CWL) behind CE. Such a offset backwards of CLR (to CE) is considerable and prevents hard at wind a strong yaw to windward (luv). In this context another effect is, that in case of heavy heeling, the slender stern of a double ender hardly developed a affect to the location of buoyancy. This looks quite different for boats with a “fat rump“, since increased buoyancy at the stern means luv yaw.
 
After all my studies I'm convinced, that Colin Archer has highly perfected the mentioned properties in his RS boats.
 
@Patrick
... I mean, hijacking for this reasons is no problem - I appreciate all contributions - that shows the range of discussion topics.
 
@Row
... Indeed, it is a premiere - I know, with this build I got into something what frankly developed an unexpected dynamic. For example a veritable machine park has accumulated ... The extent to which this build in the meantime adopted, was not predictable for me - if I would have realized the magnitude of this project from the outset – I don't know ...  - I mean, the whole thing is a little bit crazy – It's not rational, but it's fun ...

Hi,
Rigging blocks.
In ancient times and middle ages blocks were handmade by craftsmen using simple tools.
The development of shipbuilding resulted in a significant increase in the number of blocks needed for rigging and their types variety.
A typical ship of the line needed about 1000 blocks of different sizes.
In 1802 Marc Isambard Brunel proposed to the Admiralty a system of making blocks using machinery he had patented and in August 1802 he was authorized by the Admiralty to proceed.
There were 22 types of machines and their total number was 45. The machines were driven by two 22.4 kW (30 hp) steam engines.
The machines included circular saws, pin turning machines and morticing machines.
With these machines 10 men could produce as many blocks as 110 skilled craftsmen.
Production finally stopping in the 1960s.
