Rower arrangements of Ancient Greek warships

It's derived from the design and depictions of Hellenistic warships. Based on the ship's outline, the protrusions of the oars, literary descriptions, and the number of rowers assigned, there are only so many possibilities for seating.

I agree. Certainly considering the huge oars with four people pulling. The last person must've moved very far and the one sitting next to the porthole must've fine almost nothing.
