My tealight ironclad concept for making cheap and cheerful warships in bulk can be carried over to other periods. This is a first rough draught of a Greekish(ish) Trireme(ish) for my summer campaign season. I'm still working on it - the holes in the deck are because I've recycled an old Warrior-type cruiser for the hull.
I'll probably jaz it up a bit, but basically it already does the main job and doesn't take long to make. The hull could do with a few variations, each Nation will probably want their own sails, etc. Other than that, ready to go.
