What have we done for the Romans?

Apart from the tholes (rowlocks), we've pretty much made everything. Well, we also have to fashion a few knees and the slots for the foot stretcher. And the oars. The rudder, we'll get to... but apart from those trifling things, we are about ready to fit all the inside components.

The great step forward, though, was that we have now sealed the inside with epoxy: deep joy, breathtaking beauty.
