Hi Snowy
just a long shot for help - started building the Viking boat "Oseberg" (Billing boats) several years ago but only got as far as the main frame/ribs and had to stop. The kit was packed up along with other boats that had not been finished (had to work for my living in those days), now having completed 'Lancia Armata', and on the final stages of 'Bluenose ll' and have just unpacked the box containing the Oseberg, but to my horror all the part that I had built - the keel and ribs, are missing. I must have put them in another box which was since gone AWOL in two house moves we have had over the last several years.
Just came across your log about the Drakka - different scale, make and boat but the hull looks similar shape and I see on your plan (Fig.9) you have the drawing for the ribs which is not on the Oseberg plans. Interesting how the two companies differ in their build method. My deck is fully singly planked although the side planking is not unlike the your model. I suppose the design and build is different enough so stop copyright claims!
It is a long shot but if you could copy and send me that section of your plan as a starting point and I might just be able to redesign and re-cut from 4mm ply and continue to finish my Viking boat as it would be a pity to ditch the rest of the kit??
looking forward to see your finished model.
many thank
regards
