The models resemble five ships from just after 1000 A. D. Viking-age in Scandinavia.
The Skuldelev ships.
They are minifig-scale or 1:40’ish.
The largest model, Skuldelev 2, will have the dimensions Length: 80 cm, Height: 40 cm (with stand), Width: 10,5 cm
The smallest model, Skuldelev 6, will have the dimensions Length: 29 cm, Height: 21,5 cm (with stand), Width: 7 cm
There is approx. 4900 bricks in the models combined.
With 2100 going to Skuldelev 2, 1100 to skuldelev 1 and 450-700 bricks for each of the other ships.
The main source of reference is the The viking Ship Museum: Vikingeskibsmuseet i Roskilde
The focus of the museum is a permanent exhibition of the five original Viking ships excavated nearby in 1962.
The line drawings and data found at the museum is the basis for the models and the replicas Ottar, The Sea Stallion from Glendalough, Roar Ege, Helge Ask and Kraka Fyr are invaluable source material for the colors and final look.

Quoting Darth Designer
Just like in the Tv series :D
Actually never, saw an entire episode from the series. Checked out a behind the scenes after looking at your comment. The ships from the series apparently have the Oseberg ship as a main reference.
This ship is from 834 and therefore differs somewhat from these ships.
From what I can see the ships in the series have higher freeboard/or sides than the Oseberg ship.
This is probably for safety reasons.
Although it is common to put an extra board on the side when sailing on open seas.
Another weird thing is that the steering oar is portside on the ships from the series.
Starboard derives from the Scandinavian term “styrbord” meaning where the steering takes place.
