This model resembles a Byzantine Dromon.
It is in minifig-scale or 1:40’ish.
The model will have the dimension Length: 93 cm, Height: 43 cm (with stand), Width: 37 cm (with oars)
There is approx. 4350 bricks in the model.
For reference, I have used several models, paintings, drawings and descriptions of the type.
A dromon (from Greek δρόμων, dromōn, "runner") was a type of galley and the most important warship of the Byzantine navy from the 5th to 12th centuries AD, when they were succeeded by Italian-style galleys. It was developed from the ancient liburnian, which was the mainstay of the Roman navy during the Empire.
On a Dromon the ram found on earlier galleys was replaced by a ”spear”.
On the bow, there was an elevated platform with the weapon known as “greek fire”.
Behind the platform is a windlass, which has similar purposes as the (later) capstan.
The deckspace below and above the upper and lower rowers respectively, is a grid/lattice. This is makes it possible for the rowing soldiers to coordinate the rowing action.
Galley slaves was a rarity. Not even the Romans used them and not at all on a war galley. Professional rowers or soldiers operated the oars and participated in fighting the enemy when boarding.
Aft. The Dromon looked similar to older galleys. On later Italian style galleys, a rudder would replace the steering oars.
The elevated platforms on the side are a distinct dromon feature.
Other versions usually have higher platforms or even an elaborate castle centered in the middle.
I found that this made the ship potentially very heavy and/or compromising the use of sails. Not really fitting a shiptype named “runner”
