The files here represent a 1:72 scale model of a Viking 32-seater with 16 oars on each side. This ship would have been slightly more than 24 m in length, and as I mentioned elsewhere, such a hull cannot be printed out even diagonally on a reasonably large 3D printing plate (i.e. 22x22cm). The only way is in two pieces. Or in reduced scale, 1:100 or 1:144.
Version 1 of this model is the type of 32-seater that was found at Gokstad or at Oseberg. These ships were about 5 m wide and dated to ca. 850-900 AD. These finds established what most of us think of as a Viking ship today. It is easy to imagine such a one coming back from England with a fair amount of loot, both under the removable deck planks, as well as heaped around the mast in the middle. Maybe you can even try to set up a tent in the middle. I advise against displaying the ship with a full crew at the oars, plus all their shields hanging down the sides, plus the ship under full sail all at the same time. Just saying, because this is how they are shown in many romantic paintings where the crew also had horns sticking off their helmets…
Version 2 is the hull for a much slimmer ship (ca. 3 m wide), which would be consistent with the designs that appeared later, around 1000 AD. During this era much longer ships were also built that had 64-72 rowers on the oars.
Also included are two sets of oars. One is a new slim set for use only with the full size 1:72 scale model - the oars look reasonably realistic now when you put them in the hands of a crew. Unfortunately they won't work if you scale the ship down to 50% or less (unless you have a resin printer in which case you still would worry about breakage). For this case, please use the thicker set of oars that is also included here.
The rudder here also has become larger and more intricate compared to the small warship in the other post. Also, the mast now has a hole included close to the tip - that of course is to hang the yard from when the ship is displayed under sail (see picture).
