Here´s the progress (still something to do). It will stay a bireme (looks better with only two rows of oars). Maybe the Romans had a few biremes in stock before building the triremes for the battle ... The oars and the tiny rigging parts are from zvezda... nearly impossible to produce them on my own.
I had seen the beginnings of this ship but hadn't checked the thread for a while. That's some great-looking work you did!!! Now all it needs is a crew.
