Replication data for: Lusoria Rhenanan - Ein römisches Schiff am Rhein

How fast to roman warships sail and how useful is the sail if the wind comes at an angle? In order to test the sailing and rowing characteristics of Roman warships, a series of experiments was conducted. The bases for this is a roman riverboat of the type "Navis Lusoria" that was reconstructed in Regensburg in full scale. This boat was equipped with a Silva Marine NX2 system to record boat speed, wind speed and direction, boat position and speed over ground and other parameters not a vital for this study. In addition the number of oar strokes per minute was recorded by hand. In this study, we release the digital files written by the NX2 system and the digitized noted. From this data we calibrated the log response and calculated a polar diagram, which shows how fast the boat can go for each wind speed and wind direction.
