Perhaps this has been discussed before, but I suppose the planking of the deck was made by joining of planks, they could hardly have covered the whole length. Was this made at random, or was there any symmetrical pattern? Tree-nails were probably used; is there any knowledge how they were placed? At random or in a symmetrical fashion?
Also, if you go into the Vasa pictures section, you might be able to find some photos of the upper deck of Vasa, and get an impression of plank length. I think the Wasavarvet ones can give a bad impression, since it sounds like the decks were fitted with temporary planks back then for people to walk on.
Included with the book Vasa I there are more detailed and accurate plans of the decks than the ones that Fred posted to this forum.
I realized I had one in my photobucket account that might give a hint of plank length on the upper deck. You can make out some joints in the planking. Note that at the forward end of the upper deck all of the main deck planks terminate around the forward railing and then a whole row of short planks finish off the length. Not sure why they did it that way.
Perfect. I have been a Vasa fan since I as a 10-year old saw the first parts of Vasa sticking up through the water on TV. And a guided tour on the ship Gothenburg when they were building it, made me realize even more what an enormous job building Vasa must have been. Handling the hard oak with the tools they had in those days is impressive. I will start again with a model of Vasa, as I have retired from work and have a lot of time.
The deck planks were fastened with iron nails, usually two or three nails at each beam - no treenails, and no bungs over the nail heads. The planks are not of even width, and the widths on port and starboard are not the same. The butts between planks are not in any coherent pattern and not symmetrical, but probably were determined by the length of available timber. The plans I posted show the planking arrangement reasonably well, but I am working on a revised plan for the weather decks. There are also detailed deck plans of the lowest four levels included in Vasa I. The weather deck plans will be included in Vasa II, since it includes much of the belaying furniture for the rigging.
The gundecks are planked with oak, about 6 cm thick, but the weather decks are pine about the same thickness. The orlop was oak in the stern, where two guns were mounted, and thinner, lightly nailed pine in the rest.
Everything covered. I almost suspected that some other material than oak might have been used on the weather deck. What a heavy job sawing the oak for the hull and decks! Your information about the nails is very important for all model builders!
