Welcome to my account of the Dutch two-decker in POF. A while ago I bought myself a book of the writer Heinrich Winter, "A Dutch two-decker".
You can find the book review here:
I was impressed by this ship and my dream was to build it one day. Especially after seeing the reports of @Olympic1911 ( here ) and from SeaMan here and here. And the ship build by Eric van der Stoep who donated the build to the museum. Here The pictures are copywrited so only the link to the newspaper. He build this ship over several years. He was very sick, and wishes he could finish the build and donate it to a museum. His wish came true.
And my self-trained knowledge of AutoCAD is limited but enough to start with that and use it to make the drawings I needed to build the hull. I would naturally learn and get better.
But first, let me tell you something about the model. The model is derived from a Dutch two-decker from the 1660s/1670s after the contemporary model in the former Monbijou castle in Berlin. Unfortunately, the model was destroyed during a bombing in the 2nd World War. But we are fortunately to have the photos and Heinrich Winter's report at our disposal.
the model in 1930.
In the aforementioned book report, you can see that the book itself also contains a wealth of information such as very detailed photos and a line plan of the hull. You can find a lot of info of the model in that book. Enough to rebuild this ship.
So I started to make a bulkhead plan. My first intention was to build POB. I scanned the plans on my A4 scanner and used Photoshop to rejoin the small parts of the drawing to 1 piece. For use in AutoCAD it is necessary to make a negative picture. In the picture below you see a combined picture of the result.
First you start to import the negative picture into AutoCAD. And then you start to take over the white lines of the negative. That's why you need a negative, the background in AutoCad is black. I can explain how it is done but then I need a lot of pages to explain. There are tutoriols to download and even threads here on the forum how to.
*********************************************
Edit: Here are 2 links: Drafting ship plans in CAD and Interpreting line drawings for ship modeling both in pdf to download from the NRG.org
*********************************************
I can show you 2 drawings of these. The first is all the parts on an pdf to print and a 3D of the bulkheads.
You see I choose to do a upside down of a bulkhead build.
But after a while I decided not to do an POB but a POF build like the build of Eric van der Stoep did. Who I mentioned before here. I started over again and discoverd that the line plan I copied was not accurate. Maarten advised me to go to a copyshop and make a pdf in once of the drawing. Which I did. Much better and more accurate.
Learning and do-over moment.
If someone is interested in this pdf send me a pm and I will share it with you.
So I started compleet again with the drawing. By the way, the drawings in the book are not accurate. There a major mistakes in the waterlines and in the bulkheads. The distance between the waterlines are not equal and the bulk head 17 is drawn 2 times and also different from each other. This needed to be corrected. You want to create a 3D file that ensures that all the lines that meet on the outside also intersect. After a long time of big and tiny corrections I got the result.
It looks perfect after I did the corrections.
Edit, picture replacedSomehow the jpg I created of the 3D in AutoCAD got a little disturbed.
You can very easily check your drawing in 3D to make sure it has nice flowing shapes. You do this by looking at the object from many angles and seeing if the lines lie next to each other in a nice more or less parallel unit. Errors can be seen immediately.
Since the drawing is made at actual size, the scale model will be even more accurate.
The design for the keel is ready and I have already printed it so I actually can start with that.
But at this moment in my planning I started to design all the single frames (143 in total) of this ship. This is a lot of work, I need to redesign all these frames from the waterlines. At the moment I started to reshape the waterlines so I can measure each frame. For this I need a lot of study about how this was done. I use the book of Ab Hoving, Witsen and v. IJk to find out how this was done. Even I look to other building logs. Or to the drawings of Blom about the 7 Provinciën. A difficult job to do for someone with such less experience in shipbuilding.
Only this part for example took a lot of time to understand how it looks in 3D and how it is build. Not so easy as it looks.
A draw over of the book of Ab Hoving
The wood I will use for this is cherry. A coffee table I was able to buy on the internet for a few euros I was able to cut into smaller pieces at friends down the street. He also had a thickened bench and with that I now have a couple of sizeable pieces of cherry wood (European) to make these frames.
From time to time I will update this log when there is more to show, maybe to ask questions. You all know now why the build of the Prins Willem is so quiet.
Thanks for visiting my log.

Een hollandse tweedekker 1660-1670 (A Dutch two-decker) by Heinrich Winter
54 pages of the description of a contemporary model of the castle Monbijou in Berlin and 40 pictures of the model and details. In the back there are shipdrawings on 5 inlays drawed by Wolf-Dietrich Wagner. Famous Dutch two-deckers are The 7 Provinciën, The Friesland (Not very accurate to the...

Wishing you good luck, and since the most valuable seats are already taken, I will happily seat and watch in the second row. Oh...btw (by the way), if you have a hard time translating from the Russian forum, don't hesitate to ask. I still remember some words
