WebIn marine navigation, a pelorus is a reference tool for maintaining bearing of a vessel at sea. It is a "simplified compass" without a directive element, suitably mounted and provided with vanes to permit observation of relative bearings. The instrument was named for one Pelorus, said to have been the pilot for Hannibal, circa 203 BC.
