"The discovery of the remains of the ship from the 14th-13th century BCE proves that Late Bronze Age mariners could navigate the seas without a line of sight to the shore, contrary to what was previously believed, the IAA said.

The approximately 3,300-year-old ship with a cargo of hundreds of intact amphorae was found 90 kilometers off northern Israel's coast, at a depth of 1.8 km.

"Only two other shipwrecks with cargo are known from the Late Bronze Age in the Mediterranean Sea ... both found off the Turkish coast. Yet both of those shipwrecks were found relatively close to shore," said Jacob Sharvit, head of the IAA marine unit.

"There is tremendous potential here for research. [This newly discovered] ship is preserved at such a great depth that time has frozen since the moment of disaster. Its body and contents have not been disturbed by the human hand, nor affected by waves and currents, which do impact shipwrecks in shallower waters," he said."

Apparently they believed that because ships that age had only ever been found near shore.

So, I guess Donald Rumsfeld was right about what we don't know, lol.

"The earliest navigation methods involved observing landmarks or watching the direction of the sun and stars. Few ancient sailors ventured out into the open sea.

Instead, they sailed within sight of land in order to navigate. When that was impossible, ancient sailors watched constellations to mark their position.

The ancient Minoans, who lived on the Mediterranean island of Crete from 3000 to 1100 B.C.E, left records of using the stars to navigate, for instance."
