As today is the Ides of March, it seemed only appropriate to have a Trireme (this recreation is Greek, not Roman) but still good photos.

A Greek trireme, the Olympias, was constructed according to a 5th or 4th century BC design in 1985. With a length of 121 feet (40 m) , a width of 17 feet (5.5 m), and a beam (height) of 18 feet (5.3 m), it weighed 70 tons. Its maneuverability was astounding. A crew of 170 oarsmen demonstrated a 180 degree turn within one minute with a curve no wider than 2 ½ ship-lengths by the oarsmen on one side not rowing while those on the opposite side rowed. In sea trials, steady speeds of 2.15 knots (2.5 mph or 4.0 km/hr) and short-burst speeds of 9 knots (10.6 mph or 17 km/hr) were achieved.
