Five out of nine strakes done. These are the strakes that is carvel built midships. And now I will take a break from planking and do some frames. Most of the frames are of three parts; floor and two futtocks. Looking at the drawings of the wreck I see that one could say that the floor parts cover the carvel built areas and the futtocks are used for the clinker built parts of the strakes.
 

 
I enjoyed making the cargo in the last build and I have already started some of that work by reading books with titles like 'The ploughs of medieval Denmark' and such like. I never thought the history of ploughs was this exciting! My partner is amazed of how I seem to be able to be enthral by almost any subject...
 
 
 
 

@Chuck Seiler Thank you, and yes, it bends so much easier! At first I thought something was wrong as it was so easy.
 
@Mark Pearse Thank you for the great advice! Now I first soak the planks and then hit it with the heat gun. I feel like I get more consistent results by soaking them first, but I guess one could just use dry heat with training.
 
The planking has started and I'm most impressed by the work they did on this ship. The largest planks are gigantic and it is so hard to imagine them heating them over an open fire before clamping it in place.
 

 
The planking is quite special on some cogs as it generally is clinker built, but has a carvel built area where the hull contacts the beach at low tide. And it is also flush at the posts.
 
This transition between carvel and clinker is sometimes mid-plank and sometimes at the scarf joints.
 



 
The ship feels stable and I'm able to remove it from the mould to attach the nails. It's much easier to clench them now instead of waiting 'til the hull is finished.
 

the clenched ends are a bit long and I'll try to make them 1mm shorter in the future. 

Note to self, just found these....

Complete reconstruction plans for every single part of the ship. 😲

So this is why we use PE, compare the sets! 2/3rds of this lattice piece done. 

And a bit more progress on the steersman:
 
       
 
       
 
 
      
 
I've yet to do his face and a few finer details - but I'm going to leave the arms as they are until I have the ship built and the side rudder installed, so I can get them just right.
 
And the next two figures (the guys in the aftercastle
 

 
playing the mediaeval trumpet, or buisine)

PE time 

Okay, so I've made the stem and sternposts.
 
It took a bit of adjustment to get them to follow the line of the slots I'd cut in the plug. The plug is still in two halves, just held together with a G-clamp. That way I could adjust the slots until everything fitted.
 
First I made the inner curve of each post approximate as closely as possible the curve of the slot
 

 
But even that needed a bit of work -  the slots on the two halves of the plug didn't quite line up. So with a bit of trial and error, and adjustment back and forth,  I got the slot and the inner curves of the posts to mesh, so the posts would sit in the slots correctly. The two posts are not identical, so I marked them with pencil to tell them apart (B for bow, S for stern), and did the same for the plug and the keel.
 

 

 
Then I took it all apart and adjusted the outside curve of each post to match the shape in the original picture on the city seal.
 

 

 

 
I had originally thought to have the keel in a slot in the plug, but then I looked at the midships section of the Hedeby/Haithabu knarr and it seemed to be outside the body of the hull (see picture in my first post). So I decided to do it that way - to the degree that I glued in a bit of wood to fill in the slot I'd already cut in one side of the plug.
 
 But the more I thought about it, the more impractical it seemed to be - nothing seemed to work if I did it that way. And then of course it occurred to me - this is a nef, not a knarr - there's no reason to suppose the construction method was exactly the same in a non-Scandinavian ship. So I went back to my original idea, and it seems to work much better.
 
The main issue was getting the scarph joints between the keel and the stem and sternposts exactly in the right place and fitting perfectly. If I stuffed it up I'd have to re-make either the keel or one of the end posts.  
 

 

 

 
 

 
I didn't get it perfect - one of the cuts wasn't exactly at right angles across the joint - but not too bad, and I used filler made of PVA (white) glue and sawdust to fill the tiny gap I'd left on one side of one of the joints. As you can see from the photos above I used cling-wrap to ensure the posts and keel didn't stick to the plug.
 
Et voila!
 

 
And I've succumbed to peer pressure and started on the crew -  this is the helmsman under way (pear wood from the neighbour's tree and No. 11 craft knife)
 
   
 

 

 

 
(yes, all right I did want to do it, really )

I found time to take some pictures of the model and the lines of the reconstruction from Zimmermann. Hope the pictures are helpful.
 

 

 

I hope that you will publish your drawings some day. Your Bellona is really a masterpiece

Not so much perspective (though it's true that they didn't use it - the secret had been lost after Roman times and wasn't re-discovered till the Renaissance) but generally if something was important, you made it big.

Hi druxey, for some reason, maybe having to do with the grain or the stiffness of the wood, or poor hand coordination, I could not keep the cutter at a consistent angle to the table top. So the top edge wavered too much. Mounting the cutter in a handle at least keeps the angle constant for me. Still much to learn!
 
At last, I was able to start putting the waist moulding in place. I tried drilling holes for pins to keep things in place, but it was too sloppy to force the gradual curve and keep it there while the glue dried. So I made some battens that ride on the top of the planking edge underneath the moulding, clamping them to the ship side. Then it was a simple matter of clamping the moulding vertically to the batten. It is making a perfect, sweet, curve.

You could not interpret this really precies from the seals. It could also mean that the shipside is lower. Have a look at the people how big they are.
You can develop a possible hull design, which will be mostly the same for every seal. Than you can add the specific detail. Where do you find the right dimensions of such a ship? You choose the big knarrs of the vikings. There are a lot of new findings you can use for the length as basic for such a ship.
If they will find a shipwreck of a nef such as the cog of Bremen, we have to learn everything new.

I don't understand, what you mean with "stap over". The beams are the deckbeams and the deck planks are sitting on.
