FarSounder’ Next Generation Navigation Sonars
After several years of development, US-based marine electronics manufacturer FarSounder has introduced its new generation of navigation sonars at the 2012 Monaco Yacht Show—the FarSounder-500 (able to detect target 500 meters away) and FarSounder-1000 (for targets 1000 meters away).
Dancing With the Stars
The Mayans were not navigators of the seas, but they lived under the night sky and observed the movements of the stars and passed on knowledge generation to generation. They invented the “zero,” made sophisticated calculations, created a calendar and predicted celestial events, like eclipses far into the future. The Polynesians were the master mariners of history. Two thousand years before Europeans ventured across the Western Ocean, they navigated thousands of miles of open Pacific, with their entire families, to find tiny islands by the declination of stars.
