Now moving way back in time.
This ship was in use in the period from 800 BC-300 BC. The archaic and the classic periods in Greece. This was the time of Homer (not Simpson), Pythagoras (a2+b2=c2) , Thales (Waterworld), Sappho (Woman into women), The battle of Marathon (yes this is where the name is from), The battle of Thermopylae (“THIS IS SPARTA”), The Peloponnesian war, The rise of Macedon (That great Alexander fella)…

This vessel was rowed by fifty oarsmen. These were free citizens and the use of oared ships is said to have a strong link to the Greek (Athenian) Democracy.
The Penteconter would later evolve in to the more well-known Bireme and Trireme.

This was a very fast design
Yep both the ship itself and the designing of the LDD file.
