Those a small merchant ships from the Early Roman Empire and if that’s the vibe you are looking for, more power to your elbow!
If you want a real challenge try modelling the Isis 😀
“The Roman ship Isis was a very large ship that operated on the Mediterranean during the Roman Empire around 150 AD, carrying grain from Egypt to Italy. The Isis was apparently 55 meters (180 feet) long and had a beam of 13.7 meters (45 feet). Its cargo hold was 13.4 meters (44 feet) deep. It displaced 1200 short tons or 1,071 long tonnes.” – Wikipedia
